In December 2016, Muddy Waters’ Carson Block said China’s largest dairy farm operator, Hong-Kong listed China Huishan Dairy Holdings Co., is “worth close to zero” and questioned its profitability in a report. Today, with no catalyst, it suddenly almost is. The stock collapsed over 90% in minutes to a record low.
The sudden crash wiped out about $4.2 billion in market value in the stock, which is a member of the MSCI China Index.
