This week's volatility was inspired by new worries over an impending trade war with China, with President Trump on Thursday directing U.S. trade representatives to level tariffs on about $50 billion worth of Chinese imports.

Of course, some sectors are more at risk to trade concerns than others, and the energy sector itself is more contingent on the price of key natural resources. And those commodities moved higher on Friday morning. Specifically, May contracts for Light Crude Oil surged about 1.6% on the back of renewed hopes of extended OPEC production cuts.
