I have never thought much of Tang, the fund is a fairly small player & is a value player. They have had some good picks as well as some dogs, I do believe the fund has dropped in size over the past few years. BPAX is a risk/reward trade for me, I have nearly 50 open trades, BPAX is a tiny one for me. Could TANG be selling today, they will drop a stock on a dime. One of their biggest recent losers was SVNT & I believe it was a big loss for them.
