I've thought of this, but it isn't as easy as it sounds.
Reason is that when we made the scores, it's so much easier to identify quality companies that we feel will do well based on our testing and verifications.
On the short side, many stocks with horrible characteristics manage to do well. This is due to speculation involved with shorting many smaller companies and penny stocks.
Currently doing some tests to see how well the strategy would work if you go long and short, but it's definitely much easier and safer for the long side.
