NEW YORK, July 29 (Reuters) - U.S. stocks fell on Tuesday, dropping in a broad selloff as a weak outlook from courier company UPS weighed on sentiment and pressured transportation stocks.

Although a rally in telecom stocks helped to limit the broader market's decline, the S&P 500 ended below its 14-day moving average for a second straight day. Nine of the 10 primary S&P 500 sectors fell on the day.

United Parcel Service shares fell 3.7 percent to $98.86 after the world's biggest courier company slashed its earnings forecast for the year due to spending to boost capacity. It also reported second-quarter earnings that were below expectations.

Rival shipping company FedEx Corp was down 1.6 percent at $147.14. The Dow Jones Transportation index, which is often viewed as a proxy for business activity, fell 1.4 percent. It is about 3 percent away from the record closing high hit last week.   Continuación...
