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 was potentially a fairly quiet trading day when you consider how volatile the day could have been. We had Tim Geithner and Hank Paulson both getting grilled over American International Group, Inc. (AIG) again in front a House Panel, we had an FOMC rate decision, and tonight is the State of the Union speech from President Obama. Throw in disappointing housing data in December new home sales and you had a potential powder keg. Stocks spent most of the day in the red, but a move late in the day wiped all that out.

Here were the unofficial closing bell levels:

Dow 10,236.09 +41.80 (0.41%)
S&P 500 1,097.25 +5.08 (0.47%)
Nasdaq 2,221.13 +17.40 (0.79%)

Caterpillar (CAT), the famous maker of heavy equipment, was down over 7% in afternoon trading at the time of this writing. Volume of shares traded will end up being way above the norm once today's session is in the history books. The fourth quarter apparently didn't satisfy the market.

Except it should have, at least in my opinion. According to the press release, on an adjusted basis, the company made 41 cents per share. Earnings.com says analysts wanted to see 28 cents per share. Not only do we have that as a positive, but cash from operations jumped significantly to $6.3 billion in 2009 from $4.8 billion in 2008.

U.S. stock market futures were higher Wednesday morning as upbeat earnings report from late Tuesday and early Wednesday boosted sentiment. Meanwhile, investors also awaited the Federal Open Market Committee policy statement later in the day as well as President Barack Obama state of the union address.

As Fed chairman Bernanke fights for another term at the helm of the federal bank, the Federal Reserve may take a chance the housing market can stage a comeback without its support and announce today it will stick to the plan to end a $1.25 trillion program of mortgage-debt purchases in March. The Fed will release its policy statement at 2:15 p.m. Eastern.

The U.S. and global economies are starting to recover, and that's good news for Caterpillar (CAT), hence I'm reiterating my buy rating for the company's shares, first recommended on April 13, 2009 at a price of $33.02. If you bought CAT in April 2009, you're up a smart 75%.

Look for the rebound in construction and agriculture equipment to continue in the year ahead as the economy strengthens and as fiscal stimulus-related infrastructure spending around the world continues. Caterpillar's solid cost controls add to the positive mix.

TheStreet.com's Jim Cramer says it's good they could raise $19 billion so fast, but there are lots of reasons to be tentative here.

You have to have mixed emotions about this Bank of America (BAC) (Cramer's Take) deal. It's terrific that in 24 hours, a company that has no CEO and no history of making money during this tough period can raise $19 billion. But it is not terrific that $19 billion in buying power disappeared like that in a market where $19 billion actually matters, and is a precursor to maybe triple that figure that has to be raised within a short period of time.

Remember when we first did the TARP raises, the initial guys did pretty well but as we went down the path it got tougher and the stocks got hammered more, and you wanted to be short all of the financials even though the early ones popped.

Deere (DE) reported fourth-quarter results today. Even though the well-known maker of agricultural equipment had a tough year, the company's stock currently sits near a 52-week high as the bulls hope the worst is behind it.

On an adjusted basis, Deere posted a profit of 23 cents per share. This number easily beat the analysts, as they believed Q4 was only worth about 3 cents per share, according to our earnings preview.

The Street.com's Jim Cramer says that OPEC may take oil out of the equity-market equation and make stock-picking matter again.

If OPEC says it likes an oil price in the $75-78 range, as it said today, we could be looking at a nirvana moment for stocks. We know that any time oil bounces, the S&P 500 futures go up. Any time it goes down, the S&P futures go down. But if OPEC wants to keep it right here, we take oil out of the equation and make stock-picking matter again.

Right now, the Saudis are telling the big oil-shipping companies that they want to bring 1 million barrels a day into the market straight away to keep oil below $80. That can be used to overwhelm the speculators who are tying up as much as 20% of the oil fleet in the world to keep oil off the market and buoy its price. But they will not bring the oil to the market below $75.

Last week, under the guise of betting on America, Warren Buffett and his Berkshire Hathaway (BRK.A) made an offer to buy all outstanding shares of Burlington Northern (BNI) for a significant premium.

In making the announcement, Buffett confidently claimed that rail would play a big role in the recovery of the economy. What he did not say was that this was a bet on the U.S. dollar.

Nothing says manufacturing like Caterpillar (CAT). Those monster trucks made for earth-moving, digging and trucking are the epitome of making stuff in the good old USA.

Emerging markets are gaining confidence in building again, and a declining dollar makes Caterpillar equipment cheap for them. So, look for big sales gains in Caterpillar as the dollar drops.

TheStreet.com's Jim Cramer says at least one country is getting it right when it comes to economic stimulus.

How in the heck can you get 16% industrial growth and lower-than-expected consumer price inflation? How is that possible? Yet that's what we saw from China last night, and that's a tonic to pretty much everyone who is waiting for our own stimulus to kick in.

And we need it.

On Monday, Fluor (FLR) (Cramer's Take), the giant construction company, when asked if it could quantify the value of stimulus dollars currently in backlog, said "Really, the only stimulus funding we have seen directly has been the award that we got at Savannah River for some nuclear soil remediation. And, it was, I would say, we're less than $0.5 billion."

TheStreet.com's Jim Cramer says you can be bearish, but you have to admit when you're wrong.

Oh boy, I hit a nerve. My last two days of donning the bear suit and imitating the bears has brought on a cacophony of critics, all of whom think that I am attacking them personally! That's right, they think I have read them, seen them and heard them and that I am spoofing them or making fun of them.

Moreover, they think that I am wildly bullish and that I am mocking them for not wanting to buy things here.

I'm reiterating my Buy rating for Caterpillar Inc. (NYSE: CAT), first recommended on April 13, 2009, at a price of $33.02. If you bought CAT in April, you're up about 68%.

The growth story remains the same regarding Caterpillar: after a global recession that substantially reduced demand, the U.S. and global recoveries will enable construction and agriculture equipment to continue to rebound. Caterpillar's recent increase in its FY2009 EPS guidance to $1.85-2.05 adds to the positive mix. The First Call FY2009/FY2010 EPS estimates for CAT are $2.00 to $2.67.

There is no question that the recession took its tool on Caterpillar Inc. (NYSE: CAT). The company saw its stock plummet from mid 2008 through March of this year. Along the way the company was forced to layoff employees to help lower costs, but it announced today that it would be rehiring 550 of its laid off workers.

Chief Executive Officer Jim Owens announced the news and stated that the company was pleased that "signs of recovery in the global economy" is allowing it to bring back some employees.
