NEW YORK, Sept 10 (Reuters) - U.S. stock index futures were a touch higher on Wednesday, suggesting investors found few reasons to jump back into the market even after a recent string of weakness.
* The S&P 500 fell sharply on Tuesday, closing under its 14-day moving average for the first time since Aug. 12, a cautious signal for short-term momentum. The weakness came on concerns the Federal Reserve could raise interest rates sooner than some investors had expected, worries that took the yield on the benchmark 10-year U.S. Treasury note to 2.5 percent, its highest in a month.
* The positive momentum in stocks has largely come on accommodative policies from the Federal Reserve, including low rates, which currently remain in place. The S&P hasn’t had a correction - defined as a 10 percent drop from a peak - since 2012. Since then, investors have used any market decline as a buying opportunity.
* That uptrend appears intact. The S&P closed at a record on Friday and remains less than 1 percent from that level despite falling in five of the past six sessions.
* In company news, Dollar General Corp said it would take its $9.1 billion offer to buy Family Dollar Stores Inc directly to the company’s shareholders in a hostile bid.
