Trading of bearish options on the U.S. Natural Gas Fund rose to a record as the fuel fell to a seven-year low and investors bet that the exchange-traded fund tracking gas futures will keep tumbling.
Volume for puts giving the right to sell the ETF rose to 220,165 contracts, or 2.6 times the four-week average, as options traders bought the contracts to protect from a further drop if the fund extends its 61 percent slide this year. Puts traded 1.4 times more than calls, which give the right to buy the shares.
The fund, known by its UNG ticker, lost 4.7 percent to $9.01, the lowest level in its two-year history. The most-active contracts were October $7 puts, which rose 52 percent to 35 cents and accounted for almost an eighth of put volume. Ninety- four percent of those puts traded on the ask price, which indicates that buyers initiated the transactions.
“The fact that the most activity is around such an out-of- the-money put means people are expecting an extreme down move in the UNG,” said Rebecca Cheong, an equity derivatives strategist at Societe Generale SA in New York. “There’s a lot of concern.”

The UNG has been trading at a premium to its underlying natural gas assets since Aug. 12, when it announced that it couldn’t issue new shares because of limits on how many natural gas contracts it can buy. Today, shares cost as much as 18 percent more than the value of the fund’s gas contracts....MORE
