One could have known of the increase this morning but the company itself didn't file the 8k until after close. My guess is that it is 50/50 on the amount of traders that knew during market hours and traders that didn't.
This is why I believe VFIN was lurking around the ask. I believe he is tapped out. Again the simply math would suggest that he should be, however he is a shorter too so I think he may have been doing what he does knowing about the increase. Watching L2 today VFIN was on the ask all day and was ax a large part of the day. It was easily seen however that he doesn't have much shares because he would only sit as ax as long as a retail dealer was there too. The retail dealers filled 90 percent of the orders on the ask. Once VFIN would be by himself on the ask he would back off quickly with any sizable buying on the ask. Not typical note conversion dealer behavior for a dealer supposedly having shares to dump. In essence not just the math says he should be out but his actions suggest he is out as well.
Monday he may try again but I really don't think he has anything. Also since the increase was known by many already during the trading day the effect already partially hit the stock today. Many of the sellers who wished to exit due to the increase already did.
