The two possibilities that jump right out are;
1. They hit another hole 49. However this would indicate a leak, but who cares. It would be good for all of us.
2. There is a buyout offer on the table. A leak is much more likely here, as the offeror has insiders too that could leak something. This would not be good for any of us.
#1 could carry on for a few days before they announce anything which is also good. There tends to be much more movement on a rumor than on actual news.
#2 We will have some announcement tonight or before the open tomorrow.
THere are many variations of the two above mentioned possibilities, but let's be real careful what we hope for.
Best regards
