Several of these names have been beset by specific problems.
Electric utility company NRG Energy saw its CEO resign on Thursday, a move that was apparently not welcomed by investors, as the stock dropped 18 percent.
Still, a change at the top is far from the only problem for the company, which has made unsuccessful investments in renewable energy and has watched sliding natural gas prices take a big slice out of its revenues.
Meanwhile, the oil decline is not the only problem for Freeport-McMoRan, which is also highly exposed to tumbling copper.
For exploration and production companies Cheseapeake Energy and Southwestern Energy, the hit from the oil and natural gas plunge has been more head-on. Exploration and production stocks are traditionally seen as the most levered to the price of the commodities they deal in.

At this point, there appears no reason to buy these demolished stocks, argues value investing blogger Eddy Elfenbein.
"With these commodities stocks, you're really riding the commodities tiger.

"I don't think there's any values here right now."
When Evercore ISI technical analyst Rich Ross looks at these four stocks' charts, he sees "the proverbial falling knife."
"As a technician, we're paid to react when we see signs of a reversal," he said. "We wait for signs of a bottom, we don't try to anticipate that bottom." Ross sees no signs of such a bottom just yet.
