We began this blog series by talking about price and breadth momentum. In this article, we continue the discussion with risk-adjusted momentum. This takes into account the level of risk involved with a given equity. By taking into account volatility, we are able to mitigate the momentum factor from suffering from swift changes in market direction.
Risk-adjusted momentum looks at three variations:
For the sake of illustration, the below graph is the combined risk-adjusted momentum of all three variations. Portfolio Q10 performed the best with a cumulative return of 651.32%. What does Portfolio Q10 mean?
To demonstrate the performance of each momentum factor, we chose the largest 500 US equities by market capitalization, and then ranked them by its momentum factor. The universe was then divided into 10 quantiles of stocks. The top quantile (Q10) represents the stocks with the highest value for that given momentum factor, while the bottom quantile (Q1) represents the stocks with the lowest values of that momentum factor. The portfolios are rebalanced monthly and use a market-cap weighted method.

In looking closer at portfolio Q10, we notice that risk-adjusted momentum adjusted by the 50 rolling days of standard deviation had the best performance of 686.16%.
To get to this view, under Overview / Performance Overview section, select Factors Comparison tab on the top, then select Q10 from the Drop Down window.
