Here are the main points of the two-factors tests:
- All two-factor strategies we tested substantially outperformed the market with even the worst performing strategy returning 114.4% over 12 years compared with the 30.54% of the market portfolio.
- Price momentum, both 6- and 12-months played a substantial part in all 10 of the best performing two-factor strategies.
- The three best performing strategies that all generated returns of more than 1000%, all either as first or second factors, contained the highest 6-month price index as a factor.
- A low price-to-book value was also a very important factor as it formed part, either as first or second factor, in three out of four of the best performing two-factor strategies.
If you only looked at the first quintile of all two-factor strategies we tested, these were the five best and worse strategies:
