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.
