Updated from 4:09 p.m. ESTStocks closed little changed Monday as a looming speech from the Federal Reserve chairman kept traders from cashing in on lower oil prices and strong overseas sessions. The Dow Jones Industrial Average lost 5.12 points, or 0.05%, to 11,274.53, and the S&P 500 fell 2.17 points, or 0.17%, to 1305.08. Meanwhile, the Nasdaq Composite finished up 7.63 points, or 0.33%, to 2314.11. Stocks had shown broad strength last week, with blue chips closing a "quadruple witching" options-expiration Friday near five-year highs. The 10-year Treasury bond was up 5/32 in price to yield 4.65%, while the dollar was flat against the yen and euro after steadily falling last week. "Today was a day after quadruple witching, so it may have been a clean-up day for everyone," said Jay Suskind, head of institutional equity trading with Ryan Beck & Co. "There was also a lot of apprehension ahead of the Fed chairman's speech to keep anyone from taking new positions." About 1.42 billion shares changed hands on the New York Stock Exchange, with decliners beating advancers by a 9-to-7 margin. Volume on the Nasdaq was 1.97 billion, with decliners matching advancers. Investors were anxious ahead of a talk from Fed Chairman Ben Bernanke, who will be speaking in front of the Economic Club of New York this evening. "The market did nothing, showing that no one really knows what Bernanke will say," said Edgar Peters, chief investment officer with Pan Agora. "There's a growing suspicion that things will not be that positive. The message he gives will be very ambiguous or negative regarding the interest rate hike campaign." Suskind adds that while the consensus may be that "we're at the end of the rate hike cycle rather than not, but we may get different information tonight. We're hoping to get some clarity and hopefully word that inflation will stay subdued." On the economic front, the Commerce Department said the index of leading indicators fell 0.2% in February, better than the anticipated 0.3% decline for the month. However, January's number was revised from a gain of 1.1% to a gain of 0.5%. "The January revision is mostly due to the plunge in aircraft orders reported in the durable-goods numbers," said Ian Shepherdson, chief economist with High Frequency Economics. "In February, the index was pulled down by lower consumer confidence, higher jobless claims, shorter delivery times and lower building permits." On Tuesday's economic docket, investors will see the Labor Department's producer price index for February. The headline number is expected to decline 0.2% while the core number, which excludes food and energy, is expected to rise 0.2%.
