We study the expectation of implicit government debt guarantees (IGDG) on the stock trading of retail investors, exploiting the first cases of corporate bond defaults in March 2014 in China which shocked the public’s long assumed existence of IGDG in China. Our difference-in-differences analysis shows that retail investors retreat from stocks with a higher default risk (“the treated” firms) after the credit shock compared to a matched control sample. The results are stronger for non-SOE firms, firms that rely more on one-time earnings, or firms with more liquid stocks, but are not due to industry contagion, deterioration in firm performance, or seasonal effects. Institutional investors appear to retreat from treated stocks before the shock, while large shareholders of treated firms increase their ownership after the shock. When the first default shows signs of bailout, institutional investors begin to buy the treated stocks, followed by the partial reversal of retail investors’ retreat. Taken together, the first bond default in China appears to have educated millions of retail stock investors and mitigated stock speculation to some extent, which likely improves capital allocation in the Chinese stock market.
