October was a strong turnaround month, when the first half was frightening for investors. The intra-month drop for S&P 500 Index from the last September price to minimum in October was almost -8%. Such an increase in volatility during very short time might signal that a turnaround point to a bear market is getting closer.
What should you do as a long-term stock investor? Proponents of buy-and-hold and also the most orthodox value investors would argue you should not be bothered. Value investing certainly is able to beat the market index in the long term. However, what happens often is that many investors attracted by value investing hop in during the bull market and in the middle of -50% correction lose their nerve. At this time the newspapers are full of apocalypse articles such as the crash of the entire banking system being probable in 2008. People are always alluded to thinking "this time is different" as Reinhart (2011) shows. This time the crash of the entire system is possible so I will rather save remaining 50% of my net worth invested in stock market than risk a possibility of losing most of it. When the future is the bleakest, the stock market tends to turn around (stock market leads real economy by about half a year).
What can you do, if you understand that in order to beat inflation, you need to invest in the stock market? But ideally, you do not want to test your nerve.
Though it may seem counterintuitive from the traditional asset pricing perspective, momentum anomaly is one of the strongest and most durable inefficiencies in stock markets. It has been documented to exist in equity markets since 1801, see Geczy (2013).
Thus, we can use the most frequently used form of momentum filter: 10-month moving average. Just by using this simple rule: hold our selected value stock whenever its price is above 10-month moving average, we are able to decrease the drawdowns of a value portfolio significantly.
Let's have a look at the situation graphically. The following picture illustrates the stock picking strategy - simulated on QUANTPICKER website, without any momentum filter.
As we can see, the return obtained since 1990 until present is many times higher than simple buy-and-hold S&P 500, confirming the validity of value approach to stock picking. However, the drawdowns in 2008 are +50%, similar to S&P 500 Index.
Next, let's have a look at the same strategy, but introduce the moving average filter.
We obtain return which is still higher than the return of S&P 500 Index, but with significantly lower drawdowns (actually -19% - 52% on a monthly resolution).
Thus, with a monthly rebalancing the investor would be able to obtain a benefit of market return, with much lower risk. The QUANTPICKER website allows you to do just that - shadow trade their recommended portfolio, based on the factor you choose (be it value, momentum, low volatility or any other from the anomalies listed).
It would be extremely time consuming for a person who is not in the asset management industry to replicate the process himself. Just obtaining quality fundamental data is expensive (and very time consuming).
For completeness, I attach the table with the stocks selected at the end of October.
