Each session this week looked like the next, and today was no exception, as the Street watched the bears take hold once again. "Quite simply, it's more of the same," said Schaeffer's Senior Equity Analyst Joe Bell. "We had a little bit of green early on, but sellers took control and the momentum continued for one more day." By the closing bell, the Dow Jones Industrial Average (DJI) tumbled to its sixth straight loss and put in its first daily close below its 160-day moving average since mid-December.

• Did Wall Street "like" Facebook's (FB) IPO?
• The major market indexes suffered their biggest weekly losses of the year.
• Go against the current market sentiment: buy fear, not greed.

The Dow Jones Industrial Average (DJI – 12,369.38) touched a session peak of 12,492.97 around midday, and tumbled to the 12,336.76 mark in the last hour of trading. In the end, it was a down day, as the Dow slumped 73.1 points, or 0.6% -- bowing to its worst daily close since Jan. 6. Twenty of the 30 blue chips finished with losses, as Hewlett-Packard (HPQ) led the laggard with 2.7% drop. Wal-Mart (WMT) paced the 10 winning issues with a 1.2% jump. For the week, the Dow buckled 3.5%.

The S&P 500 Index (SPX – 1,295.22) broke through the 1,300 level today, declining to its worst daily finish since Jan. 17. By the closing bell, the SPX peeled back 9.6 points, or 0.7%. As the number of SPX components resting above their 10-day moving average decreased, the broad-market barometer faltered 4.3% this week.

The Nasdaq Composite (COMP – 2,778.79) endured the biggest slump of its fellow benchmarks, sawing off 34.9 points, or 1.2%. The tech-rich index faltered 5.3% on the week.

The CBOE Market Volatility Index (VIX – 25.10) solidified its loftiest perch since Dec. 15. The VIX closed out the day with a 2.5% increase, and settled 26.2% higher for the week.

Today's highlight: "Facebook's (FB) highly anticipated public offering has finally come and gone," noted Bell. "For all the hype and volatility throughout the day, the stock ended up just above the $38 initial price, pretty much near breakeven."
