Alibaba stock rose on Friday amid its longest winning streak in a year, but investors shouldn’t be too excited: shares in the Chinese tech giant are still near multiyear lows, with lots of reason for caution even as the bull case looks exciting. Shares in Alibaba rose 2% in U.S. premarket trading on Friday, with the stock on track for its seventh consecutive day in the green. Alibaba stock is down more than 75% from its late-2020 record high.
