What Does Home Bias Mean?

The tendency for investors to invest in a large amount of domestic equities, despite the purported benefits of diversifying into foreign equities. This bias is believed to have arisen as a result of the extra difficulties associated with investing in foreign equities, such as legal restrictions and additional transaction costs.

投资者倾向于在很大一部分上投资于本土资本市场，不管国外资本市场的收益能有多高，这个偏差被认为是和国外资本市场联合所遇到的困难的结果。就像，法律限制，额外的交易费用。
