This week a number of high-profile investment managers will gather at the Ira Sohn Investment Conference in NYC. What to watch: 1) Shares of Lululemon (LULU -2%) are already a bit skittish as rumors up crop up that a short seller will present his or her thesis on the retailer. 2) Bill Ackman is expected to give a lift to J.C. Penney (JCP -0.9%) and back the recent moves by the company. 3) David Einhorn will have to revisit Chiptole (CMG +1.7%) after shares rose ~30% since his attempted "nosebleed valuation" takedown of the restaurant operator. Will Einhorn double-down on his short bet?
