Today's charts: Snap falls ahead of first earnings report; Whole Foods, Fox results in focus

Yahoo Finance is tracking Snap, Whole Foods, and 21st Century Fox in intraday trading on Wednesday.

Snap (SNAP) – The parent company of Snapchat is set to report its first earnings results as a public company after the bell Wednesday. The big question is whether it can fend off rival Facebook and continue to increase its user base. RBC Capital Markets analyst Mark Mahaney expects Snap to add 7 million daily active users during the first quarter of the year and a total of 27 million in 2017. Snap added 51 million daily active users in 2016. Snap is expected to report a loss of 16 cents per share on revenue of $158.55 million, according to Bloomberg estimates.

Whole Foods (WFM) – Wall Street is bracing for Whole Foods to report its seventh quarter in a row of declining same-store sales, a very important metric for retailers. Analysts think comparable sales will drop by at least 3% during the company’s fiscal second quarter. Whole Foods is expected to report earnings per share of 37 cents on revenue of $3.73 billion, according to Bloomberg estimates. The grocery chain has been under significant pressure from shareholders. Investors Neuberger Berman and Jana Partners, which combined own nearly a 12% stake in Whole Foods, have called for the company to explore a sale.

21st Century Fox (FOXA) – Wall Street is expected to post adjusted earnings per share of 48 cents on revenue of $7.64 billion when it reports first-quarter earnings after the bell Wednesday. In a recent research note, UBS wrote, “A number of new items have combined to hinder Fox’s stock performance recently, in our view. We would view any weakness as an attractive buying opportunity as we believe all of these issues are minor, especially relative to upcoming catalysts, like re-accelerating growth for U.S. cable network affiliate revenue and India, anticipated Sky regulatory approvals and deal closure and the benefit of being in all virtual MVPD platforms.”
