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.

CBOE Volatility Index-VIX closed down 19 cents to $17.81.

Financial Select Sector (XLF) overall volatility is at 22; the 26-week average is 24.

Mosaic (MOS) April 85 and 90 calls are active on option implied volatility of 39, below its 26-week average of 43, according to Track Data, suggesting traders are taking positions into expected Q3 results on March 31.

The Russian drought has caused a spike in wheat prices. The United States Department of Agriculture (USDA) forecast lower yields for the current corn crop. Worldwide the rising demand for raw agricultural products is creating a need for more production. One way to increase production is to use more fertilizer.

Enter Mosaic (MOS), the world's largest combined producer of phosphate and potash. Mosaic is sitting on a virtual gold mine. It produces about 10 million tons of phosphate and the same for potash. Business is flourishing. Quoted in Investors.com, Chief Financial Officer Larry Stranghoener said: "The supply- demand factors are quite tight in our favor. We're scrambling to produce all we can to meet demand."

Mosaic (MOS), an expert in agricultural fertilizers that counts Potash Corporation of Saskatchewan, Inc. (POT) as a related stock, reported fiscal first-quarter numbers Monday after the bell, but the market wasn't too pleased by them. Although net profit increased, expectations were not met. We've seen this sort of situation before; it can be painful for shareholders, but that's just the way Wall Street operates.

Take a look at the press release. Earnings per share jumped from 23 cents in last year's Q1 to 67 cents this time around. In addition, operational cash flow increased more than three times to $556.2 million.

The Mosaic Company (MOS) is slated to take its turn on the earnings stage after Monday's closing bell, with the agricultural chemical concern set to unveil its fiscal first-quarter results.

Analysts surveyed by Thomson Reuters are anticipating a profit of 72 cents per share, substantially higher than the company's year-ago earnings of 23 cents per share. Mosaic has a dismal history in the earnings spotlight, having fallen short of Wall Street's consensus profit expectations in three of the past four quarters.

Alcoa (AA), Marriott (MAR) and Yum! Brands (YUM) kick off the new earnings season this week. Analysts surveyed by Thomson Reuters are looking for moderate year-over-year earnings and revenue growth in the third quarter from each of these dividend payers.

Note that Marriott and Yum! Brands have exceeded consensus estimates in recent quarters and have First Call consensus buy recommendations as well. They are also trading near their 52-week highs, while Alcoa shares are closer to the 52-week low despite a 22% rise in the past three months.

Call volume ramped up on The Mosaic Company (MOS) Wednesday, with roughly 22,000 contracts crossing the tape. By contrast, MOS was only expected to see about 7,300 calls change hands. Meanwhile, fewer than 3,700 puts were exchanged during the course of Tuesday's trading, revealing a distinct bias toward bullishly oriented options.

Taking a closer look at the day's volume, one speculator has high hopes for MOS to rally during the latter half of 2010. The trader constructed a long call spread by buying to open 1,500 contracts of the equity's December 45 call, and simultaneously selling to open 1,500 contracts of the December 55 call. MOS was trading just north of $40 at the time of this transaction, placing both calls out of the money.

Potash (POT) has been severely underperforming the broader market of late, losing almost 15% of its value during the past four weeks. Things aren't looking much better today, as the stock has surrendered nearly 3% following a downgrade at Goldman Sachs. The brokerage lowered its rating on POT (along with its peer - Mosaic ( MOS)) to "neutral" from "buy" today. Goldman also trimmed its 12-month price target on POT to $123.69 from $131, citing a number of fundamental concerns, including weak volume and lower corn prices.
