But which companies are doing well? Here are a few reporting this week that analysts are optimistic about.

Analyst upgrades:

• Merriman upgraded shares of Google (NASDAQ: GOOG) to Neutral from Sell as they believe consensus estimates for Q4 and FY09 are no longer too high.

• Oppenheimer upgraded shares of Apple (NASDAQ: AAPL) to Outperform from Perform following yesterday's disclosures regarding Steve Jobs' health. The firm has a $135 price target on Apple shares.

The market's choppy/consolidating pattern continues, suggesting the need for an additional defensive play or two (or perhaps more). And in this category Hewitt Associates is worth a review.

Hewitt Associates, Inc. (NYSE: HEW) provides a variety of human resource-related services including payroll, organizational change management, talent consulting, reward consulting, and benefits outsourcing (medical, 301K, pensions).

Analysts expect 2008 revenue growth of 4-7% with strong gains in consulting. Benefits administration revenue should advance 3-5%. Margins are adequate. The Reuters FY 2007/FY 2008 EPS consensus estimates for HEW are $1.75 to $2.12.

The company administers health care, payroll and retirement programs on behalf of hundreds of firms, for millions of employees and retirees worldwide. It also advises more than 2,300 companies on the design, implementation and operation of their own human resources programs. Hewitt employs some 23,000 associates, in 33 countries.
