Alpha Trading: Profitable Strategies That Remove Directional Risk

In Alpha Trading, Kaufman shows how to make trading profits even when there are no market trends and price shocks rock the markets every day. His strategies, long shown to be profitable, are called statistical arbitrage, or stat-arb, and they can be traded by holding positions for a few days, as he suggests, or for milliseconds as implemented by the big investment houses. They include all forms of stat-arb trading, from spreads to yield-curve trading to program trading, and from the simplest pairs trade to large-scale market neutral strategies. Kaufman covers each one in detail, ultimately showing you how to change the shape of your risk and drastically increase your probability of profiting under any market conditions.

Author’s Note:

I wanted to write this book after the collapse of the tech bubble in 2000, but it wasn’t until the subprime disaster of 2008 that I decided to do it. Investors should not be subject to the tremendous losses that the market serves up. And traders do not need to make a commitment to a long or short position all the time. There are other choices, and those choices do not necessitate compromising returns. They do require somewhat more complicated positions, but the reward is that, if the S&P collapses because of a terrorist attack, or program trading by one of the big investments houses runs amok and causes a 10 percent drop in the S&P, you are safe.

We’ve learned greater respect for risk in the past few years. It’s a lesson that we all should have learned much sooner, but any time is a good time to improve your skills. Part of that advancement is to be aware of unconscious risks. When we trade more than one stock, each trade should have equal risk. That gives each trade an equal opportunity to contribute to the final results. If you don’t do that, you are consciously or unconsciously saying that you think the trade with the largest risk is most likely to give you the best return. If that’s the case, you should only make one trade in the best item and forget about diversification.

This book is as much about the process as it is about the results. Its target audience is active traders but not necessarily intraday traders. The intended reader is someone who spends time deciding which stocks or futures markets to buy or sell and doesn’t hold a trade indefinitely when it goes the wrong way. Each step is explained, and there are examples of how the numbers should look. There is also a website that has the basic spreadsheets needed to do all the calculations.

The strategies in this book are well known to be profitable. They are called statistical arbitrage, or stat-arb, and they can be traded by holding positions for a few days, as suggested here, or for milliseconds, as implemented by the big investment houses. To trade, all you need is a spreadsheet to do a few calculations; then enter prices at the end of the day or anytime during the day when you think there is an opportunity. Trades have a high probability of success.

You cannot just believe that something works; you need to prove it to yourself. The black box approach is unacceptable and has proved a disaster to many investors. It’s your money, and you owe it to yourself to understand and verify everything—even what is shown in this book. It is one thing to be given a strategy and another to use it successfully. Once you have verified and paper-traded the strategies, you have a better chance of being successful because you have become part of the development process.

The development process is an exciting exploration. It begins with a sound premise and moves down various paths that may or may not turn out to be useful. But at the same time, it teaches valuable lessons. You understand why one idea works and another doesn’t. You understand the robust and the fragile parts of the strategies. At some time in the future, you may be called upon to change the strategy because the market has changed—volatility has dropped to a level that limits opportunity or risen to a point of unacceptable risk. Markets that used to move together no longer do so, or as in the fourth quarter of 2008, markets moved together for no apparent reason.

Without having gone through the process, you do not have the knowledge to make these changes or the confidence that they will work. This book will present important strategies that should be part of any trader’s portfolio. It will develop and explain the features that are incorporated, as well as choices that were not taken. But it is the sound premise of these ideas that is the underlying reason for its success. At the end, I hope you have learned a lot and that you trade successfully.
