Short-seller Hindenburg takes aim at Palihapitiya-backed Clover Health

Well-known short-selling specialist Hindenburg Research published a critical report on Thursday on Chamath Palihapitiya-backed insurance firm Clover Health .

Palihapitiya, who held a 27% stake in Clover Health as of Jan. 7, was among the big financial names to support last week's GameStop buying frenzy against institutional short-sellers, saying early in the slugfest that he had bought into the video game retailer.
