9:30am EST, "dumb money" investors in east coast picked up New York Times, read Buffett's article;9:30am Rest (11:30am EST), "dumb money" investors in west coast did the same thing. Therefore we have two consecutive jumps timing.
:D
vwap has volume factor in it. There is 10pts divergence between vwap and price. Although you see big volume jump by itself but it failed to compare with price change. The volume change does not match up the price change. That is how I see it.:D
