I hate it when this happens, but CHRS dropped from S&P 500 so index funds selling and will probably continue for a few days but a chance to p/u at 20% discount. For those long, it will recover quickly, hope stops didnt get hit.
No sense selling at the bottom. What else can happen, sales & earnings are stagnant, S&P drops the stock, maybe Dorrit Bern will solicit congress with an admonition that she too had a relationship with the President. But hey, maybe that'll help. She could say they're having a sale on 'pre-stained' dresses.
