Most Volatile Stocks on Earnings (FSLR; FSYS; ISRG)

I included ISRG because my friend and senior partner (deceased last year, I miss him) bought the darn thing at $5.00 and against my pleading to let some go, held it to $130 where it reversed and he got shaken out of half the position. It closed at $321.25 today.

Be careful if long FSLR. For at least the last three quarters the stock has run up in anticipation of the numbers, the company beats expectations and the stock sells off.
