From 10:34 a.m. on, Level 2 showed a large bid at $10.60. It peaked at 20,307 shares at 10:34 a.m., 0.6% of the float. The price was trading well above it.

At 11:07:39 a.m. it was pulled: the size left the book without trading there. Earlier bids of about 20,000 shares at $11.56, $10.68 and $11.93 had also come and gone between 10:23 and 10:34.

While that bid sat in the book, the stock climbed from $13.76 at 10:33 a.m. to $18.69 at 11:07 a.m. After it was pulled, the stock reached $19.18 at 11:09 a.m.

Stop It's 11:17. RDAC has been halted since 11:12. The last trade was $16.23, and trading resumes in seconds. Would you buy the reopen?
