Here are some highlights from this past week's earnings coverage on BloggingStocks:

• Amazon.com Inc. (AMZN) better-than-expected Q4 numbers due to strong holiday sales of media products.
• BlackRock Inc. (BLK) reported strong Q4 results and doubled assets under management due to an acquisition.
• Caterpillar Inc. (CAT) shares fell despite better-than-expected Q4 earnings as guidance fell short of the Street view.
• DeVry Inc. (DV) reported better-than-expected Q2 numbers due to increasing enrollments, which lifted shares.
• EMC Corp. (EMC) reported strong Q4 results that beat the Street view and offered full-year guidance.
• General Dynamics Corp. (GD) Q4 results fell short of expectations and its guidance was less than estimates.

Today had the markings of a good day, but for obvious reasons, +5.7% GDP in Q4 was only so high because Q$-2008 was so awful. We continued to see technology stocks and the broader market sell off on chart and technical levels despite what are solid earnings. The real issue today may be Washington D.C. and high valuations after so many stocks have doubled, tripled, or risen even more off of lows. This selling of everything feels like the bears might be taking back at least some control after literally have no vote for more than 10 months.

Here are today's closing bell levels:

Dow 10,102.55 -17.91 (-0.18%)
S&P 500 1,073.87 -10.66 (-0.98%)
Nasdaq 2,147.35 -31.65 (-1.45%)

Today was weak from the start, part on earnings but mostly on the trend and partly in reaction to last night's State of the Union. Bernanke's confirmation looking to be reconfirmed helped markets late in the day, as did some bargain buyers. The end of day results were much less-bad than intra-day trading lows. This may have been one more day that the bears and profit takers looked more right than wrong. Today's close on the S&P and intra-day lows on the S&P are bringing up some serious support levels that had been prior resistance levels at that 1,085 level.

Here were today's closing bell levels:

Dow 10,120.46 -115.70 (-1.13%)
S&P 500 1,084.52 -12.98 (-1.18%)
Nasdaq 2,179.00 -42.41 (-1.91%)

Shares of Mosaic Company (MOS) rallied to a new 52-week high today, topping out at $63.83 in intraday action. The stock seems to be enjoying a halo lift after sector peer Potash Corp./Saskatchewan (POT) was upgraded, but the spotlight will turn to Mosaic after today's closing bell, when the company is slated to unveil its fiscal second-quarter earnings.

Mosaic's performance on the earnings front has been mixed, with the fertilizer firm falling short of analysts' consensus expectations during three of the past four reporting periods. Ahead of tonight's release, analysts surveyed by Thomson Reuters are expecting a second-quarter profit of 35 cents per share, on average, down from Mosaic's year-ago profit of $1.12 per share. Sales are expected to ring in at $1.68 billion.

Here were today's unofficial closing bell levels:

Dow 10,414.07 +85.18 (0.82%)
S&P 500 1,114.05 +11.58 (1.05%)

TheStreet.com's Jim Cramer says it looks like the patent worries aren't so dire after all.

Now that we see that health care reform is not going to bring price caps or socialization of medicine, we are beginning to see some real expansion in the drug stocks, including Merck (MRK) (Cramer's Take), Bristol-Myers (BMY) (Cramer's Take) and Lilly (LLY) (Cramer's Take). But there is one drug stock that is continually met with skepticism -- Sanofi Aventis (SNY) (Cramer's Take), the French vaccine and pharmaceutical maker run by Christian Viehbacher. The resistance is obvious, as his biggest two drugs are coming off patent very soon, and his hope is that by 2013 the company might again reach 2008 levels.

Sounds like there's no reason to buy this one. Sounds like its 4% dividend isn't safe.

TheStreet.com's Jim Cramer says it's not too late to get on board these rocket ships.

During the great narrow bull market that was 2006-2007, anyone who hitched a ride on any bulk or oil carrier, any DryShips (DRYS) (Cramer's Take) or Diana (DSX) (Cramer's Take), or any Frontline (FRO) (Cramer's Take) or Nordic American Tanker (NAT) (Cramer's Take), or anyone who bought anything ag-related -- Deere (DE) (Cramer's Take), Monsanto (MON) (Cramer's Take), Potash (POT) (Cramer's Take) -- looked like a genius.

Beginning midyear last year, you looked like a moron.

Here are some highlights from last week's earnings coverage from BloggingStocks:

• Activision Blizzard Inc. (NASDAQ: ATVI) shares rose after it reaffirmed its full-year earnings and sales outlook.
• Automatic Data Processing Inc. (NASDAQ: ADP) will have low double-digit EPS growth, predicts one analyst.
• AutoZone Inc. (NYSE: AZO) posted a decline in earnings but a small rise in sales, sending shares lower.
• Bed Bath & Beyond Inc. (NASDAQ: BBBY) posted better-than-expected Q2 earnings and higher revenue.
• CarMax Inc. (NYSE: KMX) rallied to a new 52-week high after topping analysts' Q2 earnings expectations.
• Carnival Corp. (NYSE: CCL) reported better-than-expected Q3 results and raised its full-year guidance.

Late Friday, Potash Corp. (NYSE: POT) cut its 2009 earnings guidance due to "lower than forecasted potash sales volumes" stemming from "slow demand and limited restocking by fertilizer distributors around the world." The fertilizer company now forecasts earnings between $3.25 and $3.75 per share, down from an earlier forecast of $4 to $5 per share. The company also expects third-quarter, per-share earnings to hit at the low end of its determined range between 80 cents and $1.20. The consensus estimate calls for 93 cents per share.

POT had been a stellar performer, hitting a high in the $120 region earlier this year. However, the stock is now in the process of bouncing between the $84 level and its 20-week moving average. The current situation is currently better than the way 2008 ended.

Three stocks that deserve special call-out, in my view, for those investors who can tolerate moderate risk, due to their favorable risk/return.

Freeport McMoRan (NYSE: FCX). The global recovery appears to be underway, and with it demand for key commodities, such as copper, will increase. And Freeport, the world's second largest producer of copper, is poised to capitalize. Sell/Stop Loss if you were to buy shares in FCX: $32.

"Investing in the fertilizer business may not sound sexy, but the dynamics and fundamentals of the food business will turn it into one of the most profitable sectors you could find.," explains global expert Tony Sagami.

In his The Asia Stock Alert he suggests, "Every farmer needs to use fertilizer -- and the most used and most important fertilizer is potash. And Potash Corporation of Saskatchewan (NYSE: POT) is set to make a bundle supplying potash to the world."

"There are approximately 6.6 billion people on our planet today, but that number is expected to grow to 8.2 billion by 2030. That's a lot of mouths to feed. Plus, the amount of food each mouth is eating is also increasing.

TheStreet.com's Jim Cramer says even stocks without exposure to that country will probably be on sale today.

If China has pulled back 20%, do we have to pull back 20%, even though they were up 80% and we are up 9%? Are we so in lock step now that when China catches a cold, we are the ones with pneumonia?

I don't think so. It's such an easy story to stretch out, though you can see that our Freeports (NYSE: FCX) (Cramer's Take) and our Exxons (NYSE: XOM) (Cramer's Take) can get hammered.
