Small-Cap Stocks Lead Losses as Markets Turn

The U.S. stock market turned negative on Monday as key benchmarks relinquished early morning gains. Small-cap and tech stocks led the losses. In the absence of economic news, the markets, led mostly by computer-driven trading, may signal that stock values remain elevated and may need to retreat before pushing higher.

The S&P 500 fell below its 50-day moving average last week and has struggled to move above that threshold even after the rally on Friday.

Meanwhile, the S&P 500 (SPX) fell 6 points, or 0.3%, to 1,961.99. The Dow Jones Industrial Average (DJI) fell 36 points, or 0.2%, to 16,973.73. The Nasdaq Composite (RIXF) lost 24 points, or 0.5%, to 4,452.05. The Russell 2000 (RUT) fell 11 points, or 1%, to 1,094.

Last Friday's strong jobs report led to the S&P 500 registering its biggest gain in nearly two months. The U.S. economy last month added 248,000 jobs and the unemployment rate fell below 6%, to 5.9%, for the first time since 2008, outpacing expectations.
