Equities performed worse last week than any American Idol cast-off yet. Even as commodities endured their largest weekly drop in a quarter century, Wall Street belted out the inflationary blues, pushing each major index soundly into the red for the week.

After a confused session with stocks vacillating back and forth amid sinking commodity prices, indices closed mixed on Monday. The next day brought harmony as the indices each closed down modestly, despite reports indicating benign wholesale inflation and a slowing housing market. Stocks made the ugliest sounds of all on Wednesday. A morning report on consumer inflation fanned fears of further rate hikes, sending stocks cascading to one of their poorest sessions in three years. The dissonance continued Thursday, despite the market mostly holding its ground until the final hour of trading, when stocks slumped again. Friday's action teetered all day between high and low notes, before concluding on a positive tone for the Dow, Nasdaq, and S&P 500.

Whether this week will bring sweeter sounds may depend on the Commerce Department's preliminary report on first-quarter gross domestic product to be released on Thursday, followed by personal income and consumer sentiment data on Friday. The health of the housing market will be gauged by April figures for new home sales on Wednesday and existing home sales on Thursday.

Companies reporting earnings include Campbell Soup and Lowe's today; Borders, Medtronic, and Toll Brothers tomorrow; and Hormel Foods on Thursday.

Among the strongest, Ann Taylor's first-quarter profit more than doubled and the company raised its full-year forecast. The company's shares rose 2.9% on Friday.

Shares of Wal-Mart rose 1.4% Tuesday when it released its earnings, showing a first-quarter profit increase of 6.3%. Competitor Target did not perform as well. The retailer's shares dropped 4% Monday after reporting a 12% rise in first-quarter profits, which narrowly missed Wall Street's expectations.

The pharmaceutical company's own shares lost 0.4%. Shares of First Avenue Networks surged 40% Monday when it disclosed its agreement to a $1.5 billion merger with network operator FiberTower. Vodafone also gained 0.7% the same day amid unofficial British news reports that it may sell its position in Verizon Wireless to Verizon Communications for up to $48 billion. Meanwhile, in the face of lower first-quarter earnings, Dell made news of a different kind by announcing late Thursday that it will end its exclusive relationship with Intel and begin buying chips from Advanced Micro Devices. Shares of Dell advanced 2.6% on Friday. (See AstraZeneca's Peer Pressure Purchase.)

5. (b), (c), and (d). On Thursday federal prosecutors announced the opening of criminal probes into possible stock option abuses by Affiliated Computer Services, Caremark, Vitesse, and SafeNet.

The SEC is currently examining approximately 20 companies to investigate whether improper backdating of option grants occurred.

9. (d). The Big Board celebrated many things last week, including the series finale of NBC sitcom Will & Grace and its own birthday. While the market's dour mood may have dampened festivities, it didn't rain on speculation that NYSE Group may merge with Euronext.

10. True. Following the fast-food chain's initial public offering Thursday, its freshly made 25 million shares closed for the week at $18.60, up a tasty 9.4% from its initial trading price of $17.
