NEW YORK ( TheStreet) -- U.S. stocks finished a volatile week with a thud on Friday.
An underwhelming report on economic growth in China and the predictable return of eurozone worries drove the selling, which comes after two days of gains, including an especially strong bull run Thursday when all three major U.S. equity indices rose more than 1% and finished near the highs of the day.
Negative reactions to some high-profile earnings reports didn't help matters as financial bellwethers JPMorgan Chase (JPM) and Wells Fargo (WFC) both topped Wall Street's consensus profit view but saw their shares slump nearly 4%. Google's (GOOG) profit was above consensus as well but the company saw advertising pricing continue to weaken and was being criticized for a controversial two-for-one stock split plan.
The Dow Jones Industrial Average dropped 137 points, or 1%, to close at 12,849, just four points above the blue-chip index's low for the day. The S&P 500 fell 17 points, or 1.3%, to settle at 1370, led lower by banking sector losses after their strong run through the first quarter. Energy and materials were also among the biggest sector losers.The Nasdaq lost 44 points, or 1.5%, at 3011, as heavyweight Apple (AAPL - Get Report) lost 3% to $605.03. Shares of the iPhone and iPad maker have been among the market's best performers all year, rising more than 50%, but the stock underperformed the broad market this week, losing 4.5%, and retreating after hitting a new all-time peak of $644 on Tuesday. For the week, the Dow fell 1.6%, the S&P 500 lost 2%, and the Nasdaq retreated 2.2%. Year-to-date, the indexes are still up 5.2%, 9.0%, and 15.6% respectively. The VIX, Wall Street's investor fear index, jumped 14% to 19.53. A reading above 20 is considered an indication of heightening distress. The VIX measures implied volatility through options pricing for the S&P 500.
