Chart of the Day is the Technical Position of the Aussie Dollar

 A recent article here cited a short in the Australian Dollar as a position held by Bridgewater Associates at the turn of the year. Often global macro investors like both a fundamental case and a technical case for their positions - the bias one way or the other is a style point for differentiating between managers. The previous article gave a fundamental case for a position, this article gives a technical case based on a re-test of a (very short term) key level. 

In another article here about macro trading the (at-the-time) CIO of a $9bn global macro shop (he is now CEO and CIO) disclosed how he traded FX in 2010. He explained how observing the technical developments allowed him to change position size as markets unfold through time. A key attribute of a successful (macro) trader is to reflect the probabilities of gain/loss on a position through sizing. When the investment hypothesis on which a position is taken is confirmed by market action macro traders either initiate a position or add to it. In pattern or trend terms these could be the break-point (of a trend), a key reversal, or a successful re-test (see second graphic here). A successful re-test is very powerful because the odds of success shift considerably - the amount that can be lost is much smaller than the amount that can be gained because the spot price is much nearer the stop (just through the key support/resistance level) than the first take-profit level. This set up is illustrated below for the A$ - US$ rate.

The set up is that an ascending triangle formed from October through early February with  some acceleration in the uptrend (Graphic 2). This took the rate into the significant price band shown on the 1 year chart (Graphic 1). Note there was not a close above 1.0808 - the A$ traded above there versus the US$ intraday once but did not hold above that level. And the low close relative to the high that day (29th February) is a weak reversal signal.

The short horizontal lines at the 1.0668/1.0633 levels bound a narrow band of resistance - reflecting the candle body of the 22nd February and the market action on the 5th and 6th of March (the second and third of the three down days in a row).

The investment hypothesis is that the A$ is going down based on a fundamental case. The consolidation after the ascending triangle - the break of the uptrend on the 10th February, and sideways move since - has been done with lower lows and only one day of a minor new high (which was the weak reversal signal mentioned above).  The rate has broken below 1.0668 this week and markets have tested that level yesterday and today, and bounced off it. A weak close today (on a Friday too) would increase confidence for a trader that the A$ is reversing, and is a good short against the US Dollar now - as Bridgewater Associates have been looking for for some months.

A good macro trader would also use technical inputs other than chartism to support/undermine the assessment of market condition. Flow information, market positioning data, volume and market action all feed into the view.

All the above are used to illustrate when a global macro trader would turn a long-to-medium term fundamental view into an actual position - when the market begins to show that it is acting the same way. That is when the probabilities of upside/downside begin to tilt towards the profit potential. So it is game on for Bridgewater's A$ short position.

Book Review for "The Inner Voice of Trading"

A successful trader or investor in financial markets succeeds through a combination of factors. There is the "what they know" part; there is the trading format the trader or investors uses; and there is the less well explored element in the mix - the "other" of the trader besides technical/factual knowledge. Michael Martin's new book "The Inner Voice of Trading" (FT Press) is an exposition on this last element.

Michael Martin has been a market professional on the sell-side, a trader of his own account in stocks and commodities, and someone who has been a trader trainer for a living. He has also interviewed great traders seeking insights into the ways of working that made them great (see his website www.martinkronicle.com). This background makes him well equipped to explore what seems to be the hardest part of trading in which to excel.

Financial markets are full of smart people with MBAs, CFA qualifications, and, increasingly, PhD's.Quite sophisticated trading systems can be bought off the shelf for really very little outlay (hundreds of dollars rather than thousands). Logically there could be many more successful traders than there are. So there is an argument to be made that this last element of trading - the soft factors, and focusing on knowing yourself as an investor/trader - is one that is under explored and developed. This is the gap this book is seeking to fill.

Martin's progress through the psychology of successful trading is reinforced by evidence and quotations from prominent traders. This gives the thrust of the book credibility if not authority. In an era of the "me first" society his focus on development of the individual's own trading culture should find appeal, but though this is part self-help book, be aware that this not a step one-step two guide to to how to do it. The book has well-observed pointers but is not a manual for trading.

That written, Michael Martin's book will have resonance for those already operating in financial markets on the buy-side, and will be extremely helpful to the neophyte trader. This is a welcome addition to the oeuvre of investment books, and its' focus makes it a good companion text for those who like the "Market Wizards" series and their ilk.

Top Macro Manager Talks Through Set-Ups, Triggers and Sizing Positions

This week I heard a presentation by a senior trader at one of the large global macro hedge funds which has been in business for nearly 20 years. He put across several insights into the way of working of those who engage in the strategy. The particular trades under discussion were in foreign exchange, in the Euro/U.S. Dollar, during last year.



Fundamental Set-Up

In FX there are three elements to the fundamentals that should be aligned for putting on a position, according to the trader. The first is valuation. In FX there are several valuation models which are commonly used though each has limitations. Purchasing power parity (PPP) for a currency pair is a value which is unobservable in markets, and is a conceptual level that actual FX rates pass through without pausing. Extreme deviation from PPP is taken as an under or over-valuation. The Economist uses the price of the ubiquitous McDonald's meal to calculate the "Big Mac Index", a guide showing how far from fair value different world currencies are. The Big Mac theory, which is based on an observable purchasing-power parity, says that exchange rates should even out the prices of Big Macs sold across the world.

The second element of the fundamentals to consider is the interest rate differential between the two countries on each side of the currency pair. This is not a static element, as the FX markets (spot rate) move with forward forward rates. So expectations of future interest rate differentials are what count. The relative growth outlooks of the two economies is what the senior trader emphasised in getting a handle on interest rate differentials. For my part I would say that the perceived prospects for medium term inflation are now taking a much bigger role in the mind of the market than hithertofor in looking at interest rate differentials.

The third fundamental element to a good FX set up for a macro trader is the policy environment. Last year presented a classic opportunity (in looking at Euro related trades) in that European politicians/central bankers commented on levels and movements in traded rates (CDSs as well as bond auctions and FX parities). Some of the great macro trades have been set up by governments attempting to talk down markets when their policy objectives clash with what the markets discount as sustainable. So last year was a classic of its type in this regard, though interest rate policy specifically was a stale issue according to the bulge-bracket macro trader. That is, changes to interest rate policy were not expected to be a driver of the market condition for the trade under consideration in the time-frame envisaged. For trades at the market level like those illustrated here, and particularly in FX it is very important to understand the market drivers at the time. The graphic below indicates what the macro trader stated were the major drivers for the €/$ level last year through the different phases.



Technical Set-Up

The technical set up for a macro trade can be about flows and positioning by the various categories of market participants (say hedgers, speculators and governments). For example, the Commitments of Traders report for listed US futures showed there were very high levels of Dollar bear positions just before the monthly employment report for July 2010 released on the 6th August last year. So the positioning in the market shifted the odds of the labour market data being bad enough to move the Euro up further versus the Dollar. That date marked an interim top for the Euro versus the Dollar.

The other form of commonly used technical set up is pattern recognition, which in its crudest form is chartism. Along with the rest of the market, the senior trader from the well-known global macro firm was onto the break in the multi-quarter uptrend for the Euro (versus the Dollar) that occurred in December 2009. The Greek debt crisis powered the multi-month fall in the Euro which lasted into the middle of 2010. The break in trend of itself is often a good entry point for a trade, but as FX markets have lots of minor reversals against the major trend traders have to have tools to identify the second and third high quality entry points as the new major trend unfolds. In the middle of January 2010 there was a good secondary entry point on such a short term reversal – as is typical the secondary entry point corresponds to a support/reversal level on the previous major trend – in this case around 1.45 on the €/$ in the period 13-15th January.

This secondary, high-quality entry point can be illustrated in another trade mentioned on this website – in Gilt futures (see here and here).

Technical Set Up for Trade in Gilt Futures Showing High-Quality Entry Point



The significance from a money management perspective is that the second entry point - as the security price accelerates away from a key support or resistance level - can be a higher conviction entry point than the first. This is because the investment hypothesis ("the market is going to go down", say) has been tested by market action and passed the test. So depending on style, the macro trader can trade in several risk units at the second entry point. In no way is the second entry point a secondary entry point!

The global macro trader also disclosed the use of a particular tool to assess sentiment – the world wide web. The fund monitored the occurrence of the phrase "quantitative easing" on the web in August, September and October to ascertain the degree of dominance in the minds of investors.


Trigger

Global macro trading is often about assessing the persistence of action by the various actors in the market drama. It was interesting that the senior macro trader said that the trigger for putting on the position was often the behaviour of the markets themselves. Note that the crucial observations are across markets, not necessarily from market action within the market under consideration. So for the €/$ last year the maturity of the Euro rally that began in June was under consideration in August by the trader because the co-movements of the S&P500 (as a proxy for global equities) and the fx rate diverged. The €/$ and the SPX had synchronised price changes for a period of some months, but over the first few trading days of August days the S&P was flat whilst the € was still appreciating against the $. For the macro trader this signalled a change of behaviour was imminent for the Euro/Dollar relationship because the S&P action signalled at least a pause in the driver for the FX rate (the slowing US economy). To quote the trader directly, "divergences between markets are the best clue for market behaviour. A correlation break that lasts for one-to-two days and can indicate a movement to follow that lasts for 2-3 months." He also stated that more than 50% of a macro trader's insight comes from understanding the message of the markets, that is the behavioural inference is key. Like many traders, including those with a macro framework, the presenting macro trader only puts capital to work if the market has already started to move in the direction he wants to play.


Sizing

Sizing of positions in macro is usually a function of risk/reward and correlation. The senior trader didn't mention correlation himself in this regard, so we'll concentrate on the potential profit and loss as the key input to position sizing. The target price and stop loss levels for positions in markets are typically placed at or near significant support and resistance levels – the difference between current price levels and these two levels gives the upside/downside ratio for the potential trade. The potential loss between current levels and the stop is used to scale the maximum position size. A loss of say 5% on a position that is 20% of the gross equity of the fund would give a portfolio level loss of 1%. If two percent loss at the fund level for a single position is the outer bound then a 3% loss to the stop would equate to a 24% of equity maximum position size. The principle is determine how much you are prepared to lose – "anything else is bad discipline, or has ego in it," admonishes the trader.

This particular macro fund also uses drawdown from peak as an additional risk limiter at the level of the individual trader. So the risk capital of the trader will be reduced if his P&L is down 5% from his own peak, and he will be out of the market for a period if he loses 10% from his peak P&L, even if he is still positive on the year.


Closing the Position

The macro trader acknowledged his belief in the concept of reflexivity – Soros' concept that positive price changes themselves impact how positively investors think about the market – such that prices can waterfall down or continue upwards way beyond most expectations. Conceptualising potential price changes and unusual market impacts helps macro traders mentally prepare for a range of market outcomes. But still an all, positions have to be closed even after exceptional profits – so what feeds into the decision making at the closing of a trade? "A position should be reviewed when a price target is hit, and should be closed for sure when a lot of the market has joined you in that position."

How do you make money in macro trading? – "You need to take risk aggressively to make money, but you need to take it well." 




One of the reasons I posted this article is that the trader uses several methods I use in my own style of investing.

Consulting One - Team Working in Hedge Funds

There is no such thing as a perfect hedge fund – we are all trying. So in my role as a consultant to hedge fund portfolio managers (PMs), I am usually carrying out remedial work in some dimension. Sometimes it can be about the positioning of hedge funds commercially, but usually it is about what the portfolio managers are doing. I'm going to write a series of articles about my consulting work – this is the first.

One of the key elements I have to investigate in my consulting work is the relationship between team members. I'm going to discuss one project I did with two joint-portfolio managers of an equity long/short hedge fund. This discussion is to raise issues and to describe ways of working. The team in this case comprised two members, PM "A" and PM "B", and they ran reasonably successful long-only products. There are three topics in this snapshot – the ground rules were not well established in this example, there were some important differences in style (personal and investment style) that got in the way of successful team working, and one of the portfolio managers had an unusual trait which had a bearing on his money management style. Finally I have included some of the solutions I gave to the portfolio managers and their boss.



Ground Rules

It is not unusual for a team to move from running long-only money together to managing a hedge fund. In doing so there will, of necessity, have to be new rules of engagement. Clarity of the decision making process is very important, for internal purposes (for accountability and reward), and for external parties like potential investors. It is important that there is agreement about the specific roles to be taken, and that there is a buy-in from the off of the structure adopted. A successful agreement or understanding will have a level of detail in it that may surprise some.

One of the most basic areas not made explicit in this case was the fund's objectives and the consequences that follow from that. The two portfolio managers did not have a common, agreed understanding of what returns would make the fund they both ran commercially attractive. Therefore they did not feel the need to measure their portfolio level risk and monitor it - where they taking too much or too little risk? They just didn't know.

Another consequence of this lack of commerciality in terms of return profile is that they had no notion of what was a the worst monthly loss they could sustain without putting themselves out of active consideration by investors. The worst monthly loss is a key metric both internally and externally. Internally the metric gives an implication of where portfolio level stops should kick in. Externally it is one of a number of measures that give investors an idea of what the whole risk profile should be like – number of winning-to-losing months, drawdown, recovery period, and what is a good and bad month for the style of investment.

One of the issues which provoked some tension in the relationship between the managers was how they split between them the sectors of the equity market they worked on. It was fine, and indeed seen commonly elsewhere, that the market was split into two – one half invested in by one portfolio manager. The tension, such as it was, arose because PM B did not want to be excluded from investing in some of the sectors covered by PM A. It was never satisfactorily covered in discussion at inception in the mind of manager B, and that oversight hung over discussions in the ensuing two or three years.

It is quite usual for a PM in a team of portfolio managers to be able to initiate positions without reference to their partners. But how the team will react to change for the positions (in size or price) does need to be covered in the ground rules. Is there any right of veto, is there a different scale of decision made when the partners don't agree? Once a position is owned is it subject to hard or soft stops – do both partners have to adhere to review and exit levels? For the fund and team under discussion one of the partners was much more engaged in challenging the positions initiated by the other partner. Whilst the partners whose positions were under discussion saw this as a personal style point (one partner was just more vocal/forthright than the other), the other partner saw such challenging discussions as part of the investment process. This difference in perception and therefore activity could easily undermine a relationship under pressure because of returns.



Differences Between the Portfolio Managers

Having had some preliminary discussions for an overview, and discussed at some length how the two portfolio managers spent their time and what structure they had in place in their investment process, some clear points of difference came through. To explore these further I conducted separate structured interviews – asking the same questions to each portfolio manager gave a chance to compare attitudes, preferences, and perceptions of the two team members. To put the following list of differences into context I quote from my written report on the managers: "The managers have fantastically complementary philosophies on the market. They get on very well on a personal basis. In fact they have worked incredibly well together with some quite significant differences in tactical approaches (strategy being broadly agreed)."



Differences in Time-Frame

PM B is more comfortable with the shorter term time-frame that running a L/S hedge fund usually requires. Specifically B is much more willing to incorporate the current implications of market action into his market view by stock than PM A.



Differences in seeing Companies and Stocks

They have a similar level of respect for each other's views on companies (specifically differentiating between stocks and companies). However, when looking at equities of companies (shares) portfolio manager B can be as dispassionate about shares as he can about companies. This is in contrast to PM A – who is still prepared to argue with markets when he likes the company, even when the share price action is saying that the market does not agree with the positive (or negative) view of the company in the short term. So the feedback loop from owning the shares – the P&L – is negative for the position and getting worse (e.g. if it is a short the shares are going up) and that message from the markets, even if it is just about short term timing of the position, is being ignored.



The Fall-back Input - is it Technical or Fundamental?

(or to put it another way "short-term or long-term" or even "stock market or real world")?

Through the structured interviews of the portfolio managers it is possible to tease out where there are differences between the team members on research time. For example, in this case PM A suggested that they needed to have 300 company meetings a year, PM B thought that 100 meetings a year with company management was enough. The different perceptions of what was needed fed through to the weighting given to the fundamentals. Or, as likely, reflected the biases the managers brought into the discussion. Under pressure PM A will rely on the fundamentals to win out, whilst PM B will listen to the message of the markets and will be prepared to cut losing positions.



Conviction or Confidence?

Operators in markets, particularly traders, but to a significant degree portfolio managers as well, bring with them the baggage from their previous life experience to their decision making. So sometimes in analysing a team it is not that there are subtle style differences so much as one of the team is coming from somewhere else attitudinally (or characteristically). There can be a one-sided difference, if you like. Portfolio manager X brings with them epsilon, whilst portfolio manager Y has acquired a trait of zeta.

Through the structured interview it came through very strongly that PM A (or the Alpha member!) had a strong conviction that the most important characteristic of a successful portfolio manager was confidence. It is true that someone operating in markets has to have the belief in themselves sufficient to take on the markets, but the very strong emphasis on confidence manifested itself in the investment process in this case. This happened in two ways.

The first expression of individual confidence, if you like an assertion of confidence of an investment view, was in position sizing. Having done the analytical work PM A would take what I would consider a large position for his initial holding in a stock. Almost by definition the stock was bound to be perceived as under-valued by the market at the point of taking the initial position. If the market further under-valued that (long) position by marking the shares down (causing a loss) this would create a "better" (cheaper) buying opportunity, so PM A would have some bias to expressing confidence in his initial view of the shares by buying more. But the more important point is the size of the initial holding – he may or may not add to the position. Portfolio manager B would take an initial position of less than half the size of that taken by PM A, and look to add to it.

The second expression of confidence was the maintenance of positions of large size. PM A would always look for a further up leg in longs he owned for fundamental medium-term reasons. PM B would have a bias to trim successful positions as the positive momentum waned (to top and tail the positions). There was clear anchoring by PM A in sticking to previously successful positions, and to cut them would, in his mind, be an expression of a lessening confidence in the initial research.





Recommendations and Suggestions to Address the Issues Raised

In this particular case I wrote a 30-odd page report to the CIO of the firm as well as presented my conclusions to the portfolio managers that ran the equity long/short hedge. In the report I made a series of tiered written proposals – key recommendations, other recommendations, and finally at a more elective level, some suggestions. In response to the issues raised above here are some of the Recommendations and Suggestions forwarded:



  • You should select what you consider to be "high potential" company meetings for both PMs to attend. This will enable higher conviction positions to be established at an earlier stage with a common background on the company.
  • Be very clear and explicit (shared between you) on the reasons for having a position in a stock. Indeed there may be five potential drivers for a stock to go up (or down), but you must be clear why you own it (are short of it). The stock position should be in a portfolio for reason of how it will contribute to the portfolio characteristics (factor bets) as much as any stock specific reason (factor). This allows you to control portfolio shape in an informed way. Drift in any one position may not matter, but when aggregated across a portfolio, factors like capitalisation effects will turn you into heroes or zeroes promptly in the hedge fund format. Own positions for a reason and stick to it.
  • You both have to have the capacity to invest in all sectors of the market.
  • You need a few mechanistic rules that you can apply to take even more of the emotion out of decision making:
  1. Automatic locking in profit/reducing exposure after a stated return. So a trading position that gives a 15% plus return in two weeks is completely sold, an investment position that gives 25%-plus return in a couple of months is halved automatically. The trading position can be bought again if it is equally attractive at some point. If the fundamentals still justify a larger position (they have improved since original position taken) then the investment position can be made larger.
  2. You need a review level and hard-stop level per position. I suggest a 10% loss on book should be a review level, and 15% is a hard stop level (sell whole position, no exceptions). As a reminder the ABC Large Cap Fund has a hard stop at 8% for non-core positions and a hard stop of 10% for core positions, and the ABC Europe Fund has 5 and 10% respectively.
  • Either can initiate a position, as at present. However there must be a vote before ADDING to a position – both PMs must agree.
  • Just as you need to know yourself to be an investor, you need to know your partner if you have joint and several decision-making, rather than having a presiding genius. Because you demonstrate some differences in personal style, there are times when you don't understand where your partner is coming from. I suggest that you complete a Myers-Briggs Model™ (Extravert, Introvert, Intuitive, Sensor, Thinker, Feeler, Judger, Perciever) questionnaire. This is particularly relevant for times of stress – we each revert to a fall-back way of operating and this is the kernel of what you need to know of each other for managing money as a team. If you understand more about where each other is coming from (not intellectually but in personal style) then you will be able to tolerate the differences more easily.

Two Sides of a Short Position - A High Quality Argument on Netflix

During my time as an analyst of hedge funds in 2000-2002, and later as a consultant working on portfolio management and risk management issues with hedge fund portfolio managers, I have been granted the privilege to hear the fundamental cases for positions taken by very good managers. Hearing about a single position in detail gives a potential investor or investment advisor some insight into how managers think about their positions. When consulting I would always ask how typical the sort of position is, as there is no structural insight given in hearing about something that is outside the usual style for the manager.

I look for several key points during discussion – how did the idea arise; what made the manager devote the scarce resource of research time to the company/industry; did the manager procure or carry out primary research on the company; at what level of the company has the hedge fund manager met management and how often; what sort of catalysts does the PM like to see, and has the hedge fund manager identified a catalyst for a change in fundamentals or for a change in (stock) market perceptions? All of these points will enable an outsider to gauge whether there is an edge in research. Consideration of the edge (if there is one), along with the breadth and depth of human resources in analysis, and a view on the creativity/fertility of the manager's mind, will feed into an assessment of the quality of the manager's alpha source and the potential for consistency in the alpha stream.

So it is I read with interest the published debate about Netflix between Whitney Tilson, the value-oriented founder and Managing Partner of T2 Partners LLC (www.T2PartnersLLC.com), and Reed Hastings, CEO of Netflix Inc. You can find Tilson's full rationale for his short position in Netflix at http://seekingalpha.com/article/242320-whitney-tilson-why-we-re-short-netflix, and the response by the Netflix CEO at http://seekingalpha.com/article/242653-netflix-ceo-reed-hastings-responds-to-whitney-tilson-cover-your-short-position-now. Most unusually for such a dialogue, it is a very high quality argument.

In this case the Netflix short is smaller than any of the top ten longs in the T2 portfolio. The fund manager does not have to be right on any one position, but how he (or she) deals with being right/or wrong in money management terms is important.
