According to a report released by S3 Partners, stimulus policies driving a strong counterattack in china's stocks have already led to short sellers of US-listed Chinese concept stocks suffering losses of tens of billions of dollars. Boosted by a series of stimulus policy combinations, the csi 300 index of A-shares in china has risen more than 27% since its low on September 13, and the nasdaq golden dragon index tracking the performance of Chinese concept stocks has surged over 36%. Data from market analysis firm S3 Partners shows that this astonishing increase has evaporated nearly $3.7 billion in profits for short sellers of Chinese concept stocks so far this year, and they are currently facing about $3.2 billion in book losses.
