SIVB traced out a "V" shaped trading week. It started out Monday at 24.82, then gapped down from Monday's $24.80 close to open at $23.95 on Tuesday. Bottoming out on Wednesday, it recovered somewhat into Thursday, closing Tuesday's gap.
The final interesting part of the week's action was 200k shares near or right at the close on Friday. On Yahoo's one-day chart, I couldn't tell whether this was all one trade, or several, or whether this was on an uptick or a downtick. Someone with Level 2 or access to time and sales might enlighten us.
