Yes, perhaps some bailing. But someone is still buying and the price swing isn't much. We can't just dismiss it either. For several days there has been some bragging rights at FWR because the 4:1 ratio wasn't met. That's not unusual but it may have indicated an adjustment with negotiation. Might still all happen.
Nobody knows what will come of this offer. FWR did have two good news releases that May have helped the stock. Sure didn't hurt. But the big push to the stock came with the offer. As the time for a reply comes near, the doubt over success or failure will loom big. I think the present weakness is probably some people taking money off the table just in case the offer gets rejected. The sellers are just protecting some profit. The buyers see opportunity. I see both as being right. Whatever is best for the individual involved. I think we might know by the end of next week.
