Stock return cross-predictability refers to the ability of one stock's returns to predict the returns of another stock. Portfolio analysis involves constructing a portfolio of stocks and analyzing their performance over time. The two concepts are related in that portfolio analysis can be used to examine the cross-predictability of stock returns.
One approach to portfolio analysis is to construct a portfolio based on a set of criteria, such as industry sector, market capitalization, or company fundamentals. The portfolio can then be analyzed to determine the extent to which the returns of individual stocks within the portfolio are correlated with each other.
If there is a high degree of cross-predictability between the stocks in the portfolio, it suggests that the portfolio is not well-diversified and is exposed to systematic risk. On the other hand, if there is low cross-predictability, it suggests that the portfolio is well-diversified and has less exposure to systematic risk.
To improve portfolio diversification and reduce exposure to systematic risk, investors can use various techniques such as asset allocation, portfolio optimization, and risk management strategies. These techniques can help investors construct portfolios that are better able to withstand market volatility and provide more stable returns over the long term.
