Implied volatility for at-the-money options expiring in August, a measure of expected price swings in futures and a gauge of options prices, was 30.5 percent at 3:05 p.m. on the New York Mercantile Exchange, down from 31.5 percent yesterday.
Crude oil for August delivery gained 85 cents to settle at $80.21 a barrel on the Nymex.
U.S. durable goods orders rose 1.1 percent in May, the Commerce Department reported. The index of pending home resales climbed 5.9 percent to 101.1, matching a two-year high reached in March, figures from the National Association of Realtors showed.

Puts accounted for 55 percent of electronic trading volume. One contract covers 1,000 barrels of crude.
