stock selection factor - EV/EBIDTA ?

Hi,

I was researching what are some good stock selection quantitative factors based on backtests with longer time scale and came across this interesting book titled "What works on Wall Street" by the author James O'Shaughnessy. In the book he mentions EV/EBIDTA as a top stock selector factor based on back tests over a longer time period. The blog summarizes the returns with various value factors.

Any thoughts on including support for EV/EBIDTA as a stock selection factor?

Thanks
