Validea used the investment strategy outlined in the book Quantitative Momentum written by Wesley Gray to create our Quantitative Momentum Investor portfolio.
There are many momentum strategies out there, but most do not stand up when subjected to academic scrutiny. This strategy starts with academic theory as its foundation. It is based on extensive testing that looked at what really works in momentum investing. In his testing, Gray found that momentum works best over the intermediate-term vs. the short or long-term. He also found that momentum is more predictive of future returns when it is consistent. The resulting strategy focuses on stocks with strong one year momentum (excluding the most recent month) and looks for stocks with the least volatility within that high momentum group.
