Implied volatility for options expiring in December, a measure of expected price swings in futures and a gauge of options prices, was 31.24 percent at 3:05 p.m. in New York, after being at 31.04 on Oct. 12.
“We’re kind of range-bound here again after the rally last week,” said Fred Rigolini, vice president of Paramount Options Inc. in New York.
December-delivery crude oil rose 4 cents to settle at $92.32 a barrel on the New York Mercantile Exchange, after falling 22 cents on Oct. 12.
