Sure, you may be able to sell now and bounce back in on a 50 cent trade, but why do that here with Blackstone. There is huge interest in this company and with such a relatively low market cap I doubt it bounces around much lower. Someone mentioned ex-dividend, but is that the last dividend for the year or something? Of course not! And if for some strange stroke of luck BX were to fall more than a buck with the overall market on a bad day, just take that dry powder and buy more.
So, if you sell and sit there and wait for the stock to come in with JNJ or whatever, well, likely that neither one will this year, or at least not fall that much.
