YRC Worldwide (YRCW) is down 12 cents to $1.02 on news Delta (DAL) will replace YRCW in the Dow Jones Transportation Average. Yesterday, however, YRCW saw a morning spike to $1.28 amid talk of forced buy-ins in the top three names on the Regulation SHO Short List. Since YRCW is on that list, forced buy-ins would require shares to be bought-in at T+3. While the morning spike was short-lived, and YRCW finished with losses Monday, the order flow Tuesday seems to reflect expectations for a recovery over the next few months. Although probably not related to the Reg SHO speculation, 13.5K April 1 calls traded today and ISEE data indicates that 3,031 calls (or 74 percent of the volume on ISE) are opening customer buyers.
