Unless he comes up with a new identity, no one will take him serious. Anybody who takes him serious about anything should not be trading stocks at any level.

If he stated, 'Hey guys, I had a change of heart about BMSN.  I did the research and they have me sold'.

If he came out with a statement like that before his flip flop.  He may have some people who believe him.

He'll be back to bashing once he flips his shares, you can count on that.
