Investment strategies and risk1 of 3
How does diversification primarily affect a stock portfolio?
The answer
Answer: B. Diversification spreads investments across issuers, industries, and asset classes, which reduces company-specific and industry-specific risk. It cannot remove systematic market risk, because a broad market decline affects most securities at once. Diversification is a risk-management tool, not a guarantee of profit, and adding more stocks eventually produces diminishing reductions in unsystematic risk.
