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.

"Our Buyback Premium Portfolio is beating the S&P 500 by more than 65% since its inception in 2000; the portfolio is up 54.48% vs. a decline of 10.56% in the S&P 500 over the same time frame," notes buyback specialist David Fried.

The editor of The Buyback Letter explains, "Here's a look at three new additions to this portfolio: Forest Labs (FRX), Dollar Tree (DLTR) and Ryder System (R).

"Forest Labs is an international pharmaceutical manufacturer and marketer perhaps best known for its top selling product, anti-depression drug Lexapro, which sold $587 million in its most recent quarter.

Barnes & Noble, the Gap, RadioShack, and Sears -- that may sound like the lineup at the local mall, but in fact they are just a few of the retailers scheduled to step into the earnings spotlight this week. Following last week's disappointing January retail sales numbers from the Commerce Department but strong fourth-quarter reports from Abercrombie & Fitch (ANF) and Nordstrom (JWN), the coming week will offer plenty more data on the sector for investors to mull over.

Walmart

Bentonville-based Walmart (WMT) offered free holiday shipping, closed its Moscow office and named a chief merchandising officer during its fourth quarter. Analysts surveyed by Thomson Reuters forecast earnings for that period to come to $1.31 per share, up from $1.17 in the same quarter of last year. The world's largest retailer also is expected to post revenues of $117.7 billion for the three months that ended in January. That's 3.5% more than a year earlier.

Reese continues, "Dollar Tree is an operator of discount variety stores offering merchandise at the fixed price of one dollar.

As the earnings season begins to wind down, retail earnings move into the spotlight. Already, JCPenney (JCP), Kohl's (KSS) and Macy's (M) have posted earnings that topped consensus estimates, though the former two also offered disappointing guidance, and Nordstrom (JWN) met earnings expectations.

Many more retailers are scheduled to post their second-quarter results this week, including Walmart (WMT), Abercrombie & Fitch (ANF), and Dollar Tree Stores (DLTR), whose earnings expectations we'll take a closer look at here.
