Pier 1 Imports (PIR - Get Report) declined after reporting a wider-than-expected quarterly loss and nearly seven percent decline in net sales. The homewares retailer also announced that CEO Alex Smith will step down from his position by year's end. Rite Aid (RAD - Get Report) spiked after Walgreens  (WBA - Get Report) and the pharmacy chain pledged to sell more than 500 stores to ease concerns over their proposed merger. The two said they were "actively engaged" with the FTC in addressing antitrust worries. Lululemon (LULU - Get Report) fell after being downgraded to HOLD from BUY at Jefferies. The firm said the move was a valuation call given the stock's gains so far this year.
