Has anyone considered an all value fund portfolio. I notice betterment has a value fund tilt and their research and findings show better growth of the long term. I just backtested it and the results look pretty good.
Reminds of another recent thread :)
I dunno much about Betterment, but I found this on their website:
Our U.S. exposure covers the total U.S. market with a slight tilt towards value and small-cap stocks. The value and small-cap tilt has tended to beat the market in the long term, based on research by Nobel-prize winner Eugene Fama and Kenneth French.
So it isn't saying "just value" it is saying total market, plus value, plus small cap tends to beat the market. That's true, and pretty basic portfolio theory.
The other thing that is important to recognize is that the strategy also assumes rebalancing. IIRC, Fama and French rebalanced quarterly. Dunno what Betterment recommends, but keep that in mind, in case there are frictional costs that have to be accounted for.
