3 Trading Lessons

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.

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.

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.
