This paper investigates how the geographical distribution of shareholders in Chinese mutual fund management companies influences investment decisions. We show that mutual funds are more inclined to hold and overweight stocks from regions where their shareholders are located, thus capitalizing on a local information advantage. By examining changes in fund holdings in response to shifts in the shareholder base, we rule out the possibility that these effects are driven by fund managers’ local biases. Our findings reveal that stocks from the same region as the fund’s shareholders tend to outperform and significantly contribute to the fund’s overall performance.

The current study documents an interesting phenomenon that retail investors prefer to invest in stocks listed at the stock exchange that is geographically close to them in China. This pattern is robust when we control for the well-documented local bias within a country. Among companies with similar distances to both stock exchanges, investors still display a much stronger tendency to invest in locally-listed companies. Among stocks with similar distances to both stock exchanges, those listed in Shanghai (Shenzhen) co-move more in returns and volume, with the benchmark at the Shanghai (Shenzhen) stock exchange. Such a preference for local exchange seems not to be motivated by information advantage, because investors do not obtain abnormal returns from their trades on stocks listed nearby. Our findings provide additional evidence that non-information-based familiarity bias induces investment and that such investor biases and exchange-level sentiment influence asset price formation.
