Diamondback Energy — Shares of the company plunged 44.7% as oil prices plummeted as much as 30%. Apache Corp. fell 53.9% and Marathon Oil lost 46.8%. Exxon and Chevron, the country's two largest oil companies, shed 12.2% and 15.4%, respectively.
Walmart — Shares of Walmart rose nearly 2% amid the broader market selloff. Lower gas prices means more hands in the money of consumers, which could boost foot traffic and sales at a major consumer company like Walmart.

Twitter — Shares of Twitter rose 3.8% amid the massive stock rout, after the social media company struck a deal with investment firms Silver Lake and Elliott Management that does not mention changes to Jack Dorsey's role as CEO.

Dollar Tree, Dollar General — Shares of Dollar Tree and Dollar General were up 4.1% and 0.6%, bucking the downward trend in the broad market as investors piled into defensive stocks like discount stores.
