How we backtest our trading strategies, how we avoid overfitting by using walk-forward testing and why we adapt our strategies from time to time. One of the main questions we get is this: Why do we change the set of parameters from time to time? Is this not just curve-fitting to improve the system performance? Some think, that once you developed a strategy, you should never change it. They argue this is the only way to … Read more

In this article I would like to explain how to create a hedge strategy for an equity position, so that draw-downs, like the current one (December 2018), are minimized. During this 10-year bull market, many investors have forgotten that investing only in equities can be quite risky. It has been simple to buy the SPY S&P 500 ETF and profit from rising valuations. This year-end 20% correction makes many investors reconsider safe haven assets like … Read more

For many years, most of our strategies used long term Treasuries (TLT, TMF) as a hedge against market corrections. These Treasuries have been a safe haven asset with negative correlation to the stock market and have been used successfully to reduce the risk/volatility of our strategies. With rising rates and inflation, long term treasuries lose a part of their value as a safe haven asset. Their hedging value depends mainly on the speed interest rates … Read more
Diversification is a cornerstone to successful investing. In simple form, when measurably diverse assets are combined in a portfolio, the investors portfolio risks are reduced without any sacrifice of returns. This is a rare “free lunch”, it is well accepted part of modern financial portfolios, and to stay financially healthy it is important not to skip lunch. When one asset is going down while the other is going up, the portfolios risk is reduced without the normal penalty of risk/return trade-offs. We take advantage of that when our systems dynamically blend things like the S&P 500 and treasury bonds, which often exhibit negative correlation to each other (which is ideal).
Applying Portfolio Diversification to Strategies: Our subscribers can take this take a step further. Our investing algorithms take on a blend of the properties of their underlying assets combined with the “alpha” edges from the investing rules. The returns of each investing strategy should be thought of as an asset, which are different and unique from the underlying holdings. So holding a portfolio of strategies functions much like holding a portfolio of assets. To evaluate the risk profile of the strategy, we examine the history of the returns of those strategies, much like when holding a basket of stocks the historical returns of each stock would be evaluated.
