RE: ??????? I don't see any news either.
Take a look at Level 2. The trade that moved the price from 1.92 to 2.18 was a tiny one. A measly 160 shares, placed by a Questrade buyer off all brokerages (a place where newbies go for low commissions). I wonder if he checked the quote before placing his market order. And I have no doubt it was a market order.
Looks like all sellers were hiding in the morning. Could it be they read Buffett's letter and decided to hang on to their shares?
