US STOCKS-Retail sales, banks drag Wall Street lower

NEW YORK, April 12 (Reuters) - Wall Street declined on Friday, pulling back from record levels set a day earlier, after retail sales unexpectedly dropped last month and as results from major banks failed to impress investors.
Data showed retail sales fell 0.4 percent in March, while February's strong gain was revised down slightly. Consumer spending plays a key role in the U.S. economy, accounting for two-thirds of activity.
Another report showed consumer sentiment fell to a nine-month low in early April amid gloom about the long-term health prospects for the U.S. economy.
Investors have been rattled by indications economic growth could be softening, particularly after last week's disappointing jobs number, though that had not derailed the market rally so far.
Still, some profit taking in the market was not unexpected a day after the Dow and benchmark S&P 500 closed at record highs. For the year, the Dow has gained more than 13 percent and the broader S&P is up over 11 percent.
"That is something sitting in the back of a lot of investors' minds that we should have some pullback, whether it's short term or a bit longer term," said Tim Ghriskey, chief investment officer of Solaris Group in Bedford Hills, New York.
"We think there are a lot of people sitting on the sidelines waiting for those pullbacks to jump into the markets, which means it's likely any pullback will be short and shallow."
The Dow Jones industrial average dropped 36.79 points, or 0.25 percent, to 14,828.35. The Standard & Poor's 500 Index fell 7.16 points, or 0.45 percent, to 1,586.21. The Nasdaq Composite Index lost 11.57 points, or 0.35 percent, to 3,288.59.
The advance in equities in recent months was partly buoyed by the Federal Reserve's economic stimulus efforts, and analysts are viewing the first-quarter earnings season as a test for whether those gains are justified by corporate performance.
JP Morgan Chase and Wells Fargo were the biggest companies to report so far as earnings season got underway. Shares of both fell and the financial sector lost 0.5 percent.
JP Morgan reported higher first-quarter profit, though revenue declined; its stock was off 0.3 percent to $49.16.
Wells Fargo's profit was better-than-expected but it made fewer home loans. Its shares were down 1.6 percent at $36.90.
Earnings for S&P 500 companies are expected to grow at a modest 1.2 percent in the first quarter, down from more than 4 percent forecast in January, according to Thomson Reuters data.
