Social networking stocks were among the best gainers this year, but they were also the big losers on Monday. Twitter (TWTR), which was hammered on Friday following a 'sell' recommendation, continued to lose ground. It fell another 5 percent. That dragged down some other social networking giants. Facebook (FB) and Groupon (GRPN) both fell 3 percent.
And the biotech firm Myriad Genetics (MYGN) was clobbered. Shares fell 14 percent after Medicare and Medicaid said they will slash the reimbursement rate for the company's BRCA test to detect genes linked to a higher risk of breast cancer. That prompted a flurry of analyst downgrades.
Overall, the major averages held within a very narrow range on this penultimate day of the year. The Dow Jones industrial average (^DJI) rose 26 points, closing at another record high. But the Standard & Poor's 500 index (^GPSC) slipped less than a point, and the Nasdaq composite index (^IXIC) fell 2 points.
