Indexes kicked off the week with a win, boosted mostly by reopening stocks and news that the U.S. Food and Drug Administration (FDA) officially approved the first Covid-19 vaccine. Specifically, the Dow tacked on 215 points, after the FDA approved Pfizer's (PFE) coronavirus vaccine, which the company developed with BioNTech (BNTX). The S&P 500 closed comfortably in the black, boosted by a surge in energy stocks, while the Nasdaq nabbed a new record close. Looking ahead, investors are awaiting this week's annual Jackson Hole symposium, with regards to the latest on monetary policy.

OIL SNAPS LONGEST LOSING STREAK SINCE 2019

Today, oil snapped its longest losing streak since 2019. The positive price action came after the U.S. dollar retreated, and investors brushed aside the recent selling. As a result, October-dated crude futures tacked on $3.50, or 5.6%, to settle at $65.64 per barrel.

Gold prices also popped today, with the precious metal rising above the key $1,800 level thanks to the dented dollar. In addition, bullion's appeal was bolstered by expectations that the U.S. Federal Reserve may put a hold on the tapering of economic support as coronavirus cases rise. December-dated gold added $22.30, or 1.3%, to settle at $1,806.30 an ounce today.
