U.S. stocks fell from a 13-month high as energy producers slumped after bigger-than-estimated growth in oil stockpiles, erasing an earlier advance triggered by Hewlett-Packard Co.’s takeover of 3Com Corp. Treasuries rose.

Southwestern Energy Corp. and Range Resources Corp. slid more than 4 percent, leading declines in 39 of 40 energy companies in the Standard & Poor’s 500 Index as oil tumbled. The dollar strengthened against 15 of 16 major currencies, helping to extend declines in commodities. 3Com rallied 31 percent for its best gain since 2007 as Hewlett-Packard offered to purchase the maker of computer networking equipment for $2.7 billion.

The S&P 500 slid 1 percent to 1,087.24 in New York after climbing to 1,101.97 before the Energy Department’s report. The Dow Jones Industrial Average lost 93.79 points, or 0.9 percent, to 10,197.47. Commodities also declined, with crude oil dropping 3 percent and gold falling 0.7 percent.
