Shares of energy companies rose slightly as natural-gas prices tumbled while oil futures extended its winning streak.

Oil futures rose for the third straight session, closing around $41-a-barrel after an Organization of Petroleum Exporting Countries committee reiterated the cartel's commitment to maintaining production cuts as long as Covid-19 affected the market.

Natural gas plunged almost 10% to $2.04-a-million British thermal units for the biggest one-day percentage decline since Jan. 22, 2019, and the lowest closing price since July 31. A bigger-than-forecast weekly increase in storage and reminders from the Federal Reserve about the tenuous state of the U.S. economic recovery sparked a selloff in the commodity, a popular feedstock for the U.S. electric grid.
