I've been following Erlanger for a while and have been particularly impressed with his hedge (market neutral) strategy. I wrote a program to extract all his long/short picks since April '02, looked up the historical quotes at entry/exit (i.e. not trusting his posted prices), and computed the return.
Investing equal amounts between the long and short picks each week would have given a return of 19% over the past 7 months. Pretty damn good for such a low-risk strategy.
The tricky part is managing 30+ stocks with weekly rebalancing. But I'm working on a program to help with that and when finished plan to heavily play this strategy.
His market timing seems impressive though not infallible. But honestly, his "squeezometer" is so complicated you could claim he was right or wrong at any given time.
