From the Globe and Mail today:

Meanwhile, natural gas futures fell 5.8 cents to $8.668 per 1,000 cubic feet. On Monday, natural gas plunged 66.3 cents, or 7 per cent, to $8.726 per 1,000 cubic feet, its lowest level in nearly six months. Prices have closed lower in eight of the last 11 sessions and dropped 36 per cent from the contract's all-time trading high of $13.752, reached July 2.

The pullback is double the size of crude's recent slide. That has fed speculation on Wall Street that a large hedge fund or something like it may be near collapse and has dumped a vast amount of natural gas contracts to free up cash. Last month, SemGroup LP, based in Tulsa, Okla., folded after losing $2.4-billion in bad bets on oil futures. SemGroup's collapse came amid a massive selloff in the oil market.

“Any time you get that kind of violent price action in a short amount of time, it reeks of someone big being in trouble,” Mr. Schork said.
