: Rivian stock on track to best since December

Rivian Automotive Inc. RIVN stock was poised to end at its highest since Dec. 19, up 5% and the rare spot of green amid broad equity-market weakness. Rivian also extended its winning streak to a seventh straight session, up nearly 60% in the period, its longest winning run since an eight-day streak in September. The stock has been on a tear as the EV startup reported second-quarter deliveries that nearly tripled and one of the biggest bears on the stock backed away from a sell call. Shares of Rivian have gained 17% so far this year, compared with an advance of 15% for the S&P 500 index. SPX
