It was an unpredictable end to the session Tuesday as benchmark indexes slumped in the final hour of trading as crude oil sold off. Molson Coors (TAP) rallied in celebration of a deal between rivals Anheuser-Busch (BUD) and SABMiller (SBMRY). Investors hope Molson might snap up the assets AB InBev could unload to gain regulatory approval, like Constellation Brands (STZ) did during AB InBev's last big deal in 2013. Fortress Investment Group (FIG) spiked after announcing it will close its Fortress Macro Funds and managed separate accounts. The investment firm said all capital will be returned to investors by year's end. The International Energy Agency said Tuesday the international oil market will likely remain oversupplied well into 2016.
