Nov. 15 (Bloomberg) -- Oil options volatility fell and the underlying futures gained as U.S. retail sales increased more than projected in October, boosting optimism in the economy of the world’s largest crude-consuming nation.
Implied volatility for at-the-money options expiring in January, a measure of expected swings in futures and a gauge of options prices, fell to 37.7 at 12:30 p.m. today in New York from 40 yesterday. The Commerce Department said sales gained 0.5 percent last month following a 1.1 percent increase in September. The median forecast of 81 economists surveyed by Bloomberg News was a rise of 0.3 percent.
“Retail sales were up, and normally that should have a meaningful impact on the markets,” Al Korelin, market analyst and chairman of Blaine, Washington-based A.B. Korelin & Associates, said in a telephone interview.
