Tesla Inc.’s stock rallied 3.6% in premarket trade Tuesday, extending its prior-session gains, when it succeeded in snapping a six-day losing streak to close up more than 7%. The move came as Baird analyst Ben Kallo highlighted positive factors ahead of the EV company in the second half, including the long-awaited launch of the Cybertruck. It was the stock’s largest one-day percentage gain since March 21, when it rose 7.8%. Tesla shares have lost 15% this month, and have been on a mostly downward trajectory after the company’s second-quarter earnings in mid-July.
