MARKET SNAPSHOT: Dow Drops 100 Points As Ukraine Conflict Escalates

By Anora Mahmudova and Carla Mozee, MarketWatch

NEW YORK (MarketWatch) -- The U.S. stock market reversed gains and fell, as news of Ukrainian forces destroying Russian military units that crossed on its territory pushed investors out of riskier assets and into Treasurys on Friday.

The 10-year Treasury note yield fell 8 basis points to 2.3%, while gold futures trimmed earlier losses. Friday's losses on the main benchmarks put a cap on weekly gains.

The S&P 500 (SPX) fell 9 points, or 0.5%, to 1,945.98. The Dow Jones Industrial Average (DJI) dropped 104 points, or 0.6%, to 16,608.32. The Nasdaq Composite (RIXF) lost 18 points, or 0.4% to 4,434.45.

Ukrainian forces destroyed part of a Russian military unit that was on Ukrainian soil, a Ukrainian military spokesperson said Friday, according to news reports. Separately, NATO's secretary-general said the alliance observed a Russian "incursion" into Ukraine, denied by Russia, on Thursday night, according to the Associated Press.

The entanglement overshadowed more signs that the U.S. economy remains healthy and that company profits are increasing. Industrial production rose in July, thanks to a sizeable jump in car output, the Federal Reserve said Friday.

Meanwhile, U.S. producer prices inched up in July, a second consecutive month of gains, led by services such as transportation and warehousing, the government reported Friday. That is one of several recent inflation gauges that show price growth isn't running too hot for the Fed.

Investors shrugged off a preliminary August reading on the University of Michigan/Thomson Reuters consumer-sentiment index that showed its at the lowest level since November.

John De Clue, chief investment officer at U.S. Bank Wealth Management, said he isn't surprised that stocks have been so resilient in the face of geopolitical concerns.

"Second-quarter earnings have been better than many of us expected and the economy is growing. The fact that we are not seeing larger pullbacks mean that investors are not alarmed by the impact of geopolitical issues," De Clue said.
