讲座主要内容：

The ancient Chinese Almanac lists days that are (in)auspicious for certain actions or events. We find that the initial returns for Initial Public Offerings (IPO), an essential corporate event, are significantly lower on days listed by the Almanac as unlucky. The effect of calendar superstition is robust after controlling for a preference for lucky numbers (such as lucky listing codes and prices) and is more pronounced among firms with high investment risks and firms located in places where superstition culture is more prominent. Our results suggest that investor risk perception, but not manager superstition, plays a vital role in determining the calendar superstition effect. This finding lends support to CSRC’s recent effort to crack down on brokerages using Feng Shui - a superstition closely related to the Chinese Almanac - to predict stock market trend. Limiting brokerages use of non-science-based ideas such as Feng Shui can help to mitigate the effect of such beliefs on market price distortions and household welfare.
