Look at this article http://biz.yahoo.com/rf/010222/n22631768.html VSH is bidding $28.82/shr cash for SILI, and it already owns 80% of the common shares. As of this writing, SILI is trading at over $30. (Up from $25 since this announcement) How is this possible? Why are traders willing to pay $2 more than the price VSH is bidding for the company? I saw this same situation a few months ago, where some company was bidding $13 for MAIR, and it traded at $13.50 afterwards.
