A protracted battle in China’s food-delivery market has chopped $100 billion in market value from Alibaba Group Holding Ltd., with no end in sight for damage to profits and investor confidence.

Its Hong Kong-listed shares plunged 27% from a March high through Friday, nearly double the loss in a gauge of Chinese tech peers. Rivals JD.com Inc. and Meituan have dropped by similar measures amid daily headlines on government efforts to contain the destructive hyper-competition being dubbed “involution.”
