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 ramps up this week, and again expectations are generally low. Among the so-called bellwethers that are expected to report lower earnings year over year are CSX Corp. (NYSE: CSX), Gannett Inc. (NYSE: GCI), General Electric Co. (NYSE: GE), Harley Davidson Inc. (NYSE: HOG), Intel Corp. (NASDAQ: INTC), International Business Machines Corp. (NYSE: IBM), Johnson & Johnson (NYSE: JNJ), Marriott International Inc. (NYSE: MAR), Mattel Inc. (NYSE: MAT), Nokia Corp. (NYSE: NOK), and Yum! Brands Inc. (NYSE: YUM). Analysts surveyed by Thomson Reuters do expect the profits of CSX, Gannett, Mattel, and Nokia to be up from the previous quarter, however.

A number of financial companies, big and small, are scheduled to report second-quarter earnings this week, providing a good look at what's going on in the sector. Perhaps the best news will be coming from Citigroup and Marshall & Ilsley. While they are expected to post further losses, at least they are headed in the right direction by narrowing those losses year over year.

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.)
