Discount retailer Family Dollar Stores Inc. (FDO) reported its fiscal second quarter results this morning, topping analyst estimates and sending the stock higher in premarket trading.

For the quarter, Family Dollar reported it earned 98 cents per share, topping analyst estimates by a penny. During the same period last year, the company earned 81 cents per share.

The calendar quarter winds down this week and quarterly reports are due from Apollo Group (APOL), CarMax (KMX), Global Payments (GPN), Krispy Kreme (KKD), Lennar (LEN) and McCormick (MKC). But analysts surveyed by Thomson Reuters have high hopes for results from fertilizer and animal feed maker Mosaic (MOS), apparel maker Phillips Van Heusen (PVH) and discount retailer Family Dollar (FDO). So here's a look at what they anticipate from these three companies.

Mosaic

During its fiscal second quarter, Cargill agreed to distribute its stake in Mosaic, and Mosaic also said it would redeem senior notes. Analysts anticipate that the Minnesota-based potash producer will report per-share earnings of $1.07, a jump of 53.3% from the same quarter of last year. Mosaic also is expected to post revenue of $2.4 billion for the three months that ended in February. That's a 35.9% rise from a year earlier.
