ON THE RISE: Publisher Houghton Mifflin Harcourt IPO'ed at $12 a share on Wednesday (Nov. 13) and sold 18.3 million shares for a total of $219.6 million. The publisher won't receive money from the IPO, however, as the shares were sold by existing stockholders including Paulson & Co. (which has a 23 percent stake), Anchorage Funds and Blackrock Funds. By the weekend, the stock surged over 33% to $16.11. It's a nice sign for a debt-ridden company that filed for bankruptcy 18 months ago.
