Lululemon Earnings, Kroger Numbers, Jim Cramer's Facebook Discount

Today we keep seeing more second quarter numbers rolling out, and we'll see a pair of big names reporting today before the open. Lululemon Athletica is expected to announce earnings before the open this morning, and despite posting beats, the company's shares have fallen 45 percent in a year where it fired its CEO. Kroger shares have risen steadily over the course of the year, while bidder interest in super markets has grown -- after big gains this year, the company is seeing higher expectations for its earnings. Plus, Jim Cramer has one social stock he says is trading at a relative discount.
