I'm favoring GGT stocks that have favorable EV patterns and an AB value that is crossing through 0 from below. I'm ensuring that we're not seeing AB --> 0 from above; I think we need assurance to see the trend emerging to the long side, not the converse. Unfortunately, I cannot backtest this method, as I don't have the raw AB data -- it has to be a manual/visual check. Hence, I don't know what the edge of such an approach is (if any).
I welcome other thoughts.
