Identifying Suspicious Short Selling, But Not Who’s Behind the Trades

Last weekend, The Wall Street Journal highlighted new academic research [1] showing that investors may be trading on insider information after companies approach hedge funds for loans.

Researchers found that on average, in the five days before companies announce a loan from a hedge fund, the volume of short sales increases by 75 percent as compared with the 60 days before a deal is announced. There was no comparable uptick in betting against companies that borrowed money from commercial banks instead.
