Short traders in the American stock market are taking a historic pounding as the retail crowd charges into the most-hated names on Wall Street.

The 50 most-shorted companies on the Russell 3000 Index have now surged 33% so far this year, with the Goldman Sachs Group Inc. basket set for its best month since at least 2008.

Whether it¡¯s the Reddit trader army or the inescapable fate of bears in this market, this year¡¯s rally is following one rule: The more hated a firm, the more loved the stock.
