Answer:
An underpriced security will plot above the security market line.
Explanation:
Underpriced stocks (or securities) are those whose market value is below its earnings and risk value. Underpriced securities represent a lower risk and higher potential returns.
The security market line (SML) represents the capital asset pricing model (CAPM) and it shows risk-return relationships for securities. Since underpriced securities generate higher returns per risk, they are plotted above the SML.
