[size=12.7273px]"Five Market Wizard Lessons" by Jack Schwager, author of Hedge Fund Market Wizards
[size=12.7273px]Hedge Fund Market Wizards is ultimately a search for insights to be drawn from the most successful market practitioners. The last chapter distills the wisdom of the 15 skilled traders interviewed into 40 key market lessons. A sampling is provided below:
[size=12.7273px]1. There Is No Holy Grail in Trading
[size=12.7273px]Many traders mistakenly believe that there is some single solution to defining market behavior. Not only is there no single solution to the markets, but those solutions that do exist are continually changing. The range of the methods used by the traders interviewed in Hedge Fund Market Wizards, some of which are even polar opposites, is a testament to the diversity of possible approaches. There are a multitude of ways to be successful in the markets, albeit they are all hard to find and achieve.
[size=12.7273px]2. Don't Confuse the Concepts of Winning and Losing Trades with Good and Bad Trades
[size=12.7273px]A good trade can lose money, and a bad trade can make money. Even the best trading processes will lose a certain percentage of the time. There is no way of knowing a priori which individual trade will make money. As long as a trade adhered to a process with a positive edge, it is a good trade, regardless of whether it wins or loses because if similar trades are repeated multiple times, they will come out ahead. Conversely, a trade that is taken as a gamble is a bad trade regardless of whether it wins or loses because over time such trades will lose money.
[size=12.7273px]3. The Road to Success Is Paved with Mistakes
[size=12.7273px]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.
[size=12.7273px]4. The Importance of Doing Nothing
[size=12.7273px]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.
[size=12.7273px]5. Volatility and Risk Are Not Synonymous
[size=12.7273px]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.
[size=12.7273px]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.
