US STOCKS-Futures lower, on track for down week
* Small-cap stocks in focus after Russell 2000 selloff
* J.C. Penney soars in premarket after results
* Verizon shares up in premarket on Berkshire stake
* Futures down: Dow 34 pts, S&P 3.1 pts, Nasdaq 9.75
NEW YORK, May 16 (Reuters) - U.S. stock index futures fell on Friday, indicating that the Dow and S&P 500 could extend their decline to a third day as investors continued to be wary of weakness in small-cap names.
* Small-cap stocks weighed on Wall Street on Thursday, as the Russell 2000 briefly hit correction territory before pulling back. Investors were worried that prolonged weakness in small names could be a precursor to broader losses.
* The Dow and S&P 500 had their biggest daily decline in a month on Thursday, and the S&P closed under its 50-day moving average for the first time since April 15. In a sign of increased investor caution, the CBOE volatility index had its biggest one-day bounce in a little over a month on Thursday, and the spread between the spot VIX and the 3-month VIX at one point tightened to its smallest since April 15.
* The Russell will continue to be in focus on Friday. While the index is currently 9.3 percent away from its early March record of 1,208.65 - less than the 10 percent decline that marks a correction - it has closed below its 200-day moving average in the past two session, a sign of weakening momentum.
* J.C. Penney Co jumped 19.5 percent to $10 in premarket trading a day after posting an adjusted quarterly loss that was narrower than expected and sales that were above forecasts. Nordstrom Inc also posted earnings above expectations.
* S&P 500 futures fell 3.1 points and were below fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures fell 34 points and Nasdaq 100 futures lost 9.75 points.
* Major indexes turned lower for the week in Thursday's decline. The Dow is currently down 0.8 percent for the week while the S&P is off 0.4 percent and the Nasdaq is off 1.3 percent.
* In the tech space, Applied Materials reported revenue that was slightly ahead of expectations, while Autodesk Inc raised its full-year revenue view. Both results came out after the market closed on Thursday.
* Shares of Applied Materials rose 3 percent to $19.25 before the bell.
* Verizon Communications Inc rose 1.6 percent to $48.75 in premarket trading a day after Warren Buffett's Berkshire Hathaway Inc unveiled a new stake of 11 million shares in the company in a regulatory filing. The filings also showed that prominent hedge fund managers cut their exposure to high-profile Internet names like Netflix Inc in the quarter. (Editing by Bernadette Baum)
