CNBC Senior Energy Correspondent Sharon Epperson discusses a mystery trade in natural gas:
There have been big swings in natural gas prices Thursday, moving the most-active July, 2011 contract between $4.70 and $5.00. But traders aren't talking about the hot weather or a bigger-than-expected build in natural gas storage. Instead, they are still baffled by a trade that whipsawed natural gas futures in an 8 percent range in just 15 seconds Wednesday evening.
"The price action did not just dictate somebody screwing up, making a mistake on an order,” says floor trader John Woods of J.J. Woods Associates. “I honestly thought my computer was broken.”
