I don't think so. He does OK actually. Don't have the actual numbers in front of me but his $50k portfolio started in 2006 is now I think over 250k.
To put things in perspective, he sold everything and cashed up befofe Xmas, so his buy/sell signals are not to be taken as underlying sentiment towards an individual stock.
Still, he must have followers, and if he buys, I presume they also buy.
