Natural gas futures fluctuated in New York before a weekly report that may show a larger-than-average stockpile increase.
Gas moved between gains and losses as government data scheduled for release tomorrow in Washington may show that inventories rose 99 billion cubic feet in the seven days ended May 31, according to the median of 15 analyst estimates compiled by Bloomberg.
