Dec. 5 (Bloomberg) -- Crude options volatility fell as the underlying oil futures remained within a two-week trading range of about $5.
Implied volatility for at-the-money options expiring in January, a measure of expected price swings in futures and a gauge of options prices, was 27.18 percent on the New York Mercantile Exchange as of 3:20 p.m., down from 27.49 yesterday.
“There wasn’t really much of a move in volatility,” said Fred Rigolini, vice president of Paramount Options Inc. in New York. “Some people come in and just buy some straddles on whim because at some point, at least by the end of the year, we could break out of this range.”
January-delivery crude oil fell 62 cents, or 0.7 percent, to settle at $87.88 a barrel on the Nymex. Since Nov. 19, crude has traded in an intraday range between $85.36 and $90.33.
The most active options in electronic trading today were January $85 puts, which rose 4 cents to 57 cents a barrel on volume of 3,761 lots at 3:28 p.m. February $79 puts were the second-most active, with 3,031 lots exchanged as they advanced 8 cents to 64 cents.
Bets that prices would decline, or puts, accounted for 52 percent of trading volume.
The exchange distributes real-time data for electronic trading and releases information the next business day on open-outcry volume, where the bulk of options activity occurs.
