Good on you Steve Vai. I bought some more too at $8.15 earlier this week.
I understand that for given methods of working out fair value, different methods produce different results. Based on 15 years of real history and RYM's current metrics, anything under $8.30 is an awesome buy as far as I am concerned (not to say the SP can't get even more awesome from a buyer's perspective).
Anything under $8.30 is in The Ultra Zone.
