NEW YORK (AP) - Stocks lost momentum heading into midday trading Friday despite an increase in U.S. manufacturing last month. The Dow Jones industrial average was up 11 points, or 0.1 percent, to 15,556 as of 12:10 p.m. Eastern. The blue chips had been up 103 points earlier. The Standard & Poor's 500 index was down two points, or 0.1 percent, to 1,754. The Nasdaq composite was the weakest of the three indexes, losing 12 points, or 0.3 percent, to 3,907. The Nasdaq was hit with more technical problems. Trading was halted on the Nasdaq Options Market as of 10:36 a.m. Eastern time, according to Nasdaq OMX. Regular stock trading was not affected. On Tuesday, Nasdaq indexes weren't updated for about 45 minutes because of a technical problem, and on Aug. 22 trading was halted on the Nasdaq Stock Market for three hours because of a separate technical glitch. The Nasdaq Options Market is one of the larger stock options markets, handling to roughly 11 percent of stock options trading in the U.S., according to the Options Clearing Corporation. A stock option gives the holder the right, but not the obligation, to buy or sell a stock at a fixed price in the future. Movement in the options markets can impact the broader stock market. Stocks had been moderately higher most of the morning after the Institute for Supply Management reported that its manufacturing index increased to 56.4 from 56.2 in September. That was better than the 55.1 figure economists were expecting, according financial data provider FactSet. The improvement came during what could have been a difficult month for the U.S. economy, with a partial government shutdown that lasted 16 days and a narrowly averted default on the U.S. government's debt, which could have rattled financial markets. The stock market had a strong October. The S&P 500 closed at a record high seven times during the month, most recently on Tuesday. It ended October with a gain of 4.5 percent. In the bond market, the yield on the 10-year Treasury note rose to 2.60 percent from 2.56 percent. Among stocks making big moves: Chevron fell $2.71, or 2 percent, to $117.20.

The Container Store more than doubled on its first day of trading on the New York Stock Exchange. The company raised $225 million in its initial public offering, pricing 12.5 million shares at $18 each. The stock soared $18.43 to $36.46. First Solar jumped $9.26, or 18 percent, to $59.48.
