Home bias is a cognitive phenomenon where investors prefer to allocate a disproportionate amount of their investment capital into domestic stocks or assets, rather than diversifying into foreign markets. This behavior often stems from a sense of familiarity and comfort with local companies, leading to a neglect of potential opportunities outside one’s home country. It can significantly impact investment strategies and overall portfolio performance, particularly in the context of stock market investing.

Review Questions
How does home bias affect an investor's portfolio diversification?
Home bias negatively impacts an investor's portfolio diversification by causing them to invest heavily in domestic assets at the expense of international opportunities. This lack of diversification increases the overall risk of the portfolio since it becomes overly reliant on the performance of the local market. By ignoring foreign markets, investors may also miss potential higher returns that could be achieved through a more balanced global asset allocation.
Discuss the psychological factors that contribute to home bias in investment decision-making.
Psychological factors such as familiarity, comfort, and cognitive biases play significant roles in contributing to home bias. Investors tend to favor companies they recognize and understand, which are often local firms. Additionally, cognitive biases like overconfidence can lead individuals to underestimate the risks associated with their domestic investments while overvaluing their knowledge about these companies. This psychological comfort can cloud judgment and deter investors from exploring diverse opportunities in foreign markets.
Evaluate the implications of home bias on market efficiency and the broader investment landscape.
Home bias can create significant implications for market efficiency by leading to mispricing of assets. When a large number of investors concentrate their investments in local stocks, it may inflate their values beyond intrinsic worth while undervaluing foreign assets. This behavior distorts market signals and can hinder price adjustments that reflect true economic conditions. Furthermore, persistent home bias might limit the potential for portfolio growth and reduce overall economic integration in a globalized investment landscape.
