Among the stocks with unusual options volume is discount retailer Dollar General Corp. (NYSE:DG), down 13% at $79.86. Total intraday volume is at 16 times the norm, with short-term bulls buying to open the near-the-money weekly 8/26 80-strike call. The shares are being pressured by disappointing second-quarter earnings and sales, and have found a place on the short-sale restricted (SSR) list.
