By Caroline Valetkevitch

NEW YORK, Sept 11 (Reuters) - U.S. stocks were lower at midday on Thursday as energy shares extended their decline and shares of Apple (NasdaqGS: AAPL - news) dipped.

The S&P 500 energy index was down 0.4 percent, on track for its fourth straight decline. Shares (Frankfurt: DI6.F - news) of Nabors Industries dipped 2.4 percent and shares of Chesapeake Energy fell 2.1 percent.

Nabors shares dropped following news Pamplona Capital Management LLP's private equity fund had sold a stake in the oilfield services provider.

"If you look at the price action it the energy/commodity space, the market seems to be tracking that pretty closely," said Art Hogan, chief market strategist at Wunderlich Securities in New York. "There really hasn't been a supply shock" so oil prices have come down.

Some investors had been pricing in disruptions due to overseas tensions. U.S. crude oil prices were nearly flat while benchmark Brent crude were at a two-year low on Thursday.

Apple was down 1 percent.

Among gainers, shares of JDS Uniphase were up 11.6 percent, a day after it said it would split into two public companies as it looks to expand in data communication market and strengthen its network business.

Wall Street's weakness follows limp jobless claims data, which pushed investors to continue taking profits in a market that had rallied to repeated records.
