This week brings a small flurry of end-of-the-calendar-quarter earnings reports. And for the most part, the expectations of the analysts surveyed by Thomson Reuters aren't very high. Companies expected to report declining earnings in the most recently concluded quarter include America's Car-Mart Inc. (NASDAQ: CRMT), Bed Bath & Beyond Inc. (NASDAQ: BBBY), ConAgra Foods Inc. (NYSE: CAG), Jabil Circuit Inc. (NYSE: JBL), Jackson Hewitt Tax Service Inc. (NYSE: JTX), Monsanto Co. (NYSE: MON), and Sonic Corp. (NASDAQ: SONC).

Pulte (NYSE: PHM) and Centex (NYSE: CTX) agreed to merge, creating America's largest homebuilding company. CTX shareholders will receive 0.975 PHM common shares for each CTX they own. The combined company will have a market cap of $4.1B with $3.4B in cash on its balance sheet. PHM April option implied volatility is at 93, May is at 97; below its 26-week average of 102, according to Track Data, suggesting decreasing price movement.

Centex April option implied volatility is at 108, May is at 118; near its 26-week average according to Track Data, suggesting non-directional price movement.

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%)
• QLogic Corp. (NASDAQ: QLGC): $0.31 per share (+29.0%) on revenues of $170.0 million (+21.2%)
• FLIR Systems Inc. (NASDAQ: FLIR): $0.32 per share (+28.1%) on revenues of $275.2 million (+44.0%)
• Juniper Networks Inc. (NASDAQ: JNPR): $0.30 per share (+26.7%) on revenues of $927.4 million (+26.2%)
• Waters Corp. (NYSE: WAT): $0.75 per share (+17.3%) on revenues of $391.6 million (+11.1%)
• Flextronics International Ltd. (NASDAQ: FLEX): $0.29 per share (+17.2%) on revenues of $8.7 billion (+57.3%)
• EMC Corp. (NYSE: EMC): $0.19 per share (+10.5%) on revenues of $3.7 billion (+12.9%)

For nervous investors and analysts looking for good news on the earnings front, it's been a week of mixed blessings. However, judging by the expectations for the following ten so-called barometers of the U.S. economy, or important sectors of it, things could be looking up. All these companies are scheduled to report quarterly results next week (April 21 to April 25).

These first six companies are expected by analysts surveyed by Thomson Financial to post growth in profits in the most recent quarter, compared to the same period of last year:

• Texas Instruments Inc. (NYSE: TXN): 22.9%
• Apple Inc. (NASDAQ: AAPL): 21.8%
• Boeing Co. (NYSE: BA): 20.5%
• AT&T (NYSE: T): 13.8%
• Pepsico Inc. (NYSE: PEP): 7.7%
• 3M Co. (NYSE: MMM): 5.5%

Things keep getting worse and builders get more and more cautious. In fact, according to the Commerce Department's most recent survey, housing starts dropped 10% to an annual pace of 1.19 million in September from a 1.33 million rate in August. That's worse than economists expected. Briefing.com's survey showed economists estimated a more modest fall to 1.29 million.

We haven't seen a housing market this weak since 1993 and the future doesn't look any better. Housing permits were down 7% to an annual rate of 1.23 million in September from 1.32 in August. That's the lowest level for permits in 12 years.

This news follows the report that the Mortgage Bankers Association will release today at its annual convention indicating falling mortgage originations and a builder's confidence survey that was released Tuesday indicating that builder's confidence is at record low levels. The nation's builders are hit hard. The most recent to report was the nation's largest, D. R. Horton (NYSE: DHI), whose orders dropped by 39%. Last week, Moody's downgraded Lennar (NYSE: LEN), Centex (NYSE: CTX) and Pulte (NYSE: PHM) homes to junk bond status.
