Regional banking issue Comerica (CMA) is in focus today, after announcing last night that it will sell $800 million in common stock in order to repay its debt to the U.S. government. Under the terms of the Troubled Asset Relief Program (TARP). Comerica owes Uncle Sam about $2.25 billion. At this point, the Dallas-based bank is among the few remaining financial institutions yet to repay its TARP debt.

This morning, Comerica priced its common stock offering at $35 per share, representing a discount to Monday's close at $36.29. The shares have quickly backpedaled as a result, slipping below recent support at their 10-day and 20-day moving averages.

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

• American Express Co. (AXP) doubled its bottom line in Q4 while its provisions for losses fell.
• Blockbuster Inc. (BBI) warned of weakness in Q4 and lowered its guidance, sending shares lower.
• Coach Inc. (COH) better-than-expected Q2 earnings were accompanied by sales growth, but shares fell.
• Comerica Inc. (CMA) posted a smaller-than-expected Q4 loss, sending shares to a 52-week high.
• CSX Corp. (CSX) posted Q4 earnings that topped estimates but its revenue fell short of expectations.

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

• Advanced Micro Devices Inc. (AMD) shares declined despite an earnings beat and a positive outlook
• Bank of America Corp. (BAC) reported that its Q4 loss widened more than expected by Wall Street.
• Capital One Financial Corp. (COF) reported better-than-expected earnings but shares declined.
• Colgate-Palmolive Co. (CL) is seen as on-track to record double-digit earnings growth in 2010.
• Cree Inc. (CREE) strong earnings and revenue growth sent shares to a new 52-week high.

Comerica Incorporated (CMA) shares are rising today after the company reported earnings this morning, posting a fourth-quarter loss of $29 million, or 41 cents per share, beating analysts' forecasts of a 49-cent loss. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on CMA.

CMA opened this morning at $34.35. So far today the stock has hit a low of $34.35 and a high of $36.87. As of 12:00, CMA is trading at $36.54 up 2.97 (8.9%). The chart for CMA looks bullish and S&P gives CMA a positive 4 STARS (out of 5) buy ranking.

Last week, JPMorgan Chase & Co. (JPM) led off the coming parade of earnings from the big banks when it reported better-than-expected fourth-quarter and full-year earnings, though its revenue fell short of estimates.

Plenty more earnings from the financial sector are due out this week. Analysts surveyed by Thomson Reuters anticipate fourth-quarter earnings growth from American Express Co. (AXP), Bank of New York Mellon Corp. (BK), Hudson City Bancorp Inc. (HCBK), SLM Corp. (SLM) and US Bancorp (USB).

The earnings crunch begins in earnest this coming week, with companies from Johnson & Johnson (NYSE: JNJ) and PepsiCo Inc. (NYSE: PEP) to Southwest Airlines Co. (NYSE: LUV) and Harley-Davidson Inc. (NYSE: HOG) scheduled to report results for the quarter just ended. But with the ongoing turmoil in the markets, much attention is on the tech and financial sectors. This week will provide plenty to mull over on both counts.

Wall Street expectations for tech stocks are fairly optimistic. Analysts surveyed by Thomson Financial are looking for chip maker Altera Corp. (NASDAQ: ALTR) and software/service company iGate Corp. (NASDAQ: IGTE) to be the sector's biggest earnings gainers of the week. Altera is expected to report earnings of 30 cents per share (up 33.3% from a year ago) on revenue of $355.1 million. Altera had previously forecast flat sales for the quarter, and shares fell to a 52-week low last week. iGate is expected to report earnings of 14 cents per share (up 42.9%) on revenue of $55.6 million. India-based iGate recently spun off its Mastech consulting services. Shares are down 45.0% in the past three months, and also reached a new 52-week low last week.

San Jose-based Novellus Systems Inc. (NASDAQ: NVLS), on the other hand, is expected to report that net income tumbled 90.4% from a year ago to 4 cents per share, on revenue of $245.6 million. Novellus fell to a 52-week low early last week, and shares are down 44.5% year to date.

After the implosion of IndyMac Bancorp (NYSE: IMB) and news of the deterioration of Fannie Mae (NYSE: FNM) and Freddie Mac (NYSE: FRE) last week, there's bound to be a certain level of trepidation as the earnings crunch begins this coming week and many big financial companies report. Here's a look at what Wall Street was expecting (see The week in preview: Expectations as the earnings crunch begins for expectations of other reporting companies.)
