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

• AirTran Holdings Inc. (NYSE: AAI) reported its third consecutive quarterly profit and will increase capacity.
• Amazon.com Inc. (NASDAQ: AMZN) shares soared after it reported very strong Q3 numbers.
• Apple Inc. (NASDAQ: AAPL) reported stellar Q4 results, driven by the popularity of Macs and iPhones.
• BlackRock Inc. (NYSE: BLK) Q3 earnings soared, due in part to a tax benefit, and assets managed grew.
• Broadcom Corp. (NASDAQ: BRCM) revenue surged sequentially but note the would be flat going forward.
• Caterpillar Inc. (NYSE: CAT) beat Q3 earnings expectations and shares rose though revenue slumped.

Today was one of those days where it felt like it would be an up-day and most traders were feeling good, but the last hour's trading came down so far so fast that traders had little feel whether we'd have an up or down session until right before the closing bell.

Oil inventories were not a huge surprise like the week before, but the data sent oil much higher and then a weak US dollar only added to oil price gains. Some may use the Beige Book as the reason for the sell-off, but it might be how little the government expects Wall Street executives to work for if they are a TARP bank.

Here were today's unofficial closing bell levels:

Dow 9,956.91 -84.57 (-0.84%)
S&P 500 1,081.36 -9.70 (-0.89%)
Nasdaq 2,150.73 -12.74 (-0.59%)

TheStreet.com's Jim Cramer says you'll miss some great opportunities if you blindly believe all the bad news.

You want a rebuke to the "never-ending woes of commercial and residential real estate mortgage bonds"? You get one every day in this market, and today is no different. Look at what is up big today: Genworth (NYSE: GNW) (Cramer's Take), Lincoln National (NYSE: LNC) (Cramer's Take), Wyndham (NYSE: WYN) (Cramer's Take), Regions Financial (NYSE: RF) (Cramer's Take) and Zions (NASDAQ: ZION) (Cramer's Take). Each in its own way needs the residential or commercial real estate markets to be robust to thrive, and if the myriad articles I read about the horrible state of the mortgage bond market and the dim commercial real estate prospects were true, why would you be making money in Wyndham, a gigantic timeshare company? How could Regions and Zions be rallying? They are among the worst of the worst; unless you consider Genworth and Lincoln National, which are supposed to be roadkill because of all of their mortgage bonds.

Wall Street's optimism in last week's preview about the earnings of tech stocks wasn't misplaced, as there were many more positive surprises than negative ones among the stocks we looked at. This week will bring plenty more data for investors in and watchers of the sector to mull over. Apple Inc. (NASDAQ: AAPL), AT&T Inc. (NYSE: T), and Microsoft Corp. (NASDAQ: MSFT), for example, are expected by analysts surveyed by Thomson Financial to post modest earnings gains from a year ago, to $1.11 per share (on $8.1 billion in sales), $0.72 per share (on $31.3 billion in sales), and $0.47 per share (on $14.8 billion in sales) respectively. All three of these companies ended the week closer to their 52-week lows than highs, and analysts on average consider them each a buy.

Here's a look at some of the week's biggest expected earnings gainers and decliners in the sector:

• Baidu.com Inc. (NASDAQ: BIDU): $1.25 per share (+44.0%) on revenues of $134.7 million (+103.2%)
• Broadcom Corp. (NASDAQ: BRCM): $0.44 per share (+38.6%) on revenues of $1.3 billion (+33.8%)

TheStreet.com's Jim Cramer says he doesn't want to make a move until he sees the action.

We aren't oversold enough anymore, and we are up too much. Meanwhile, the next run is on the insurers, as we can tell from the erratic nature of the way that group is trading.

Oh, and what's the deal with Sallie Mae (NYSE: SLM) (Cramer's Take)?

There's not a lot of respite here in part, again, because of Lehman and the default of so much Washington Mutual paper.

We just aren't ready for what is happening yet, and we keep getting surprised about where the paper is. The rescue bill will help, but the pork attachments are so horrible that I believe, ex-FDIC, they have made it tougher to pass, not easier.

This week, we've seen two major buyout deals come undone: the $6.1 transaction for Penn National Gaming Inc. (NASDAQ: PENN) and TPG's play for Bradford & Bingley. In fact, according to FactSet Research, about 20% of leveraged buyouts (LBOs) since mid-2007 have been terminated.

Despite all this, some deals are getting done. Perhaps the most notable is the BCE (NYSE: BCE) LBO. BCE has reached an agreement with its private equity sponsors and banks to close its $51 billion LBO. This will represent the biggest buyout in history.

Now, there are some wrinkles. The closing date will be extended to December and there will not be any dividend payments for the rest of the year. The break-up fee was also upped from $1 billion to $1.2 billion.

Yet, the fact is that the price tag will remain unchanged (at $42 per share). No doubt, this is a big feat, especially in light of the credit crunch.

Apparently, there was much discussion about renegotiating the price. Then again, the prospects of massive litigation were daunting, as we have seen in a variety of other deals such as with Clear Channel, SLM (NYSE: SLM) and Huntsman Corp. (NYSE: HUN).

"Since the market started its downturn early this year, I have avoided all financial stocks and resisted the temptation of value plays," says Dave Dyer.

In his Dave Dyer's Newsletter, he explains, "Well, it is now time to violate both of those prohibitions at once." Here, he looks at a new buy for SLM Corporation (NYSE: SLM), commonly known as Sallie Mae, the nation's largest provider of college loans and savings programs."

"There must be some financial areas that have predictable, growing demand, willing customers who actually have low default rates, and securitization processes that do not involve the type of financial engineering that is only intended to hide risk.

"Well, there is such an area, and it even involves a product that it makes sense to finance since it will actually increase in value over time. I'm talking about student loans.
