Advice from Hedge Fund Market Wizards

Jack Schwager has written a new book "Hedge Fund Market Wizards". He sums up the advice given by these wizards in 15 points. Amazon.com has published five of these, and, I am giving below three of the published five.

3. The Road to Success Is Paved with Mistakes
Ray Dalio, the founder of Bridgewater, the world's largest hedge fund, strongly believes that learning from mistakes is essential to improvement and ultimate success. Each mistake, if recognized and acted upon, provides an opportunity for improving a trading approach. Most traders would benefit by writing down each mistake, the implied lesson, and the intended change in the trading process. Such a trading log can be periodically reviewed for reinforcement. Trading mistakes cannot be avoided, but repeating the same mistakes can be, and doing so is often the difference between success and failure.

4. The Importance of Doing Nothing
For some traders, the discipline and patience to do nothing when the environment is unfavorable or opportunities are lacking is a crucial element in their success. For example, despite making minimal use of short positions, Kevin Daly, the manager of the Five Corners fund, achieved cumulative gross returns in excess of 800% during a 12-year period when the broad equity markets were essentially flat. In part, he accomplished this feat by having the discipline to remain largely in cash during negative environments, which allowed him to sidestep large drawdowns during two major bear markets. The lesson is that if conditions are not right, or the return/risk is not sufficiently favorable, don't do anything. Beware of taking dubious trades out of impatience.

5. Volatility and Risk Are Not Synonymous
Low volatility does not imply low risk and high volatility does not imply high risk. Investments subject to sporadic large risks may exhibit low volatility if a risk event is not present in the existing track record. For example, the strategy of selling out-of-the-money options can exhibit low volatility if there are no large, abrupt price moves, but is at risk of asymptotically increasing losses in the event of a sudden, steep selloff. On the other hand, traders such as Jamie Mai, the portfolio manager for Cornwall Capital, will exhibit high volatility because of occasional very large gains-not a factor that most investors would associate with risk or even consider undesirable-but will have strictly curtailed risk because of the asymmetric structure of their trades. So some strategies, such as option selling, can have both low volatility and large, open-ended risk, and some strategies, such as Mai's, can have both high volatility and constrained risk.

As a related point, investors often make the mistake of equating manager performance in a given year with manager skill. Sometimes, more skilled managers will underperform because they refuse to participate in market bubbles. The best performers during such periods are often the most imprudent rather than the most skilled managers. Martin Taylor, the portfolio manager of the Nevsky Fund, underperformed in 1999 because he thought it was ridiculous to buy tech stocks at their inflated price levels. This same investment decision, however, was instrumental to his large outperformance in subsequent years when these stocks witnessed a prolonged, massive decline. In this sense, past performance can sometimes even be an inverse indicator.

Sudarshan sir, one question that would be helpful to all of us...
Why that the Nifty and Bank Nifty Futures are trading at huge discount to the cash levels??? Yesterday's market action itself was saying a good movement on the upside what we have seen today but futures at discount Is it that the most of the market participates expecting a big correction or what is the inference? .... would be pleased to know sir

namaskar sudarshan ji,

june 6th's nifty spot high is 5010.45 where as in the icharts eod chart 5010 is the upper band of the bollinger bands. now the question is will this upper band and the level 5010 act as a very tough resistance for nifty tomorrow and therefore nifty can fall down from here ? please enlighten on this. also let us know how much importance should be attached to an indicator like bollinger bands.

warm regards
rajiv malik

Response to Sh. Vasantkumar: It is possible that many stocks (component of Nifty 50) are turning Ex-dividend in this series resulting in the cash value going down (e.g. stock price in beginning of the month is 100 Rs and dividend date is say 10th June with Rs. 5 as dividend than stock price will adjust and be Rs. 95 on 11th June). This could explain such huge discount. ( I have not checked dividend calendar but is usually available on many web sites)

Sudarshan ji : Your views, please !
