Yes, The ask Basics went higher then the Limit Orders right after the announcement of the secondary. This almost never happens and was completely unrelated to the offering. Because of this, the Short Selling Stop Orders broke down and the share price went sky high. Keep in mind the At-the-Money Options also had a small part in this also. Now, that the Capped Indices have completed their fill, everything should be back to normal.
I hope this helps.
