Answer:
Buy the stock because it is underpriced and investor will make money in the near future.
Step-by-step explanation:
Required rate of return is defined as the estimated return am investor wants to gain for taking on a certain amount of risk when investing in securities.
The higher the risk the higher the required rate of return.
If the expected rate of return exceeds the required rate of return then the investor will consider the share underpriced and experiencing supernormal growth.
For example if a stock has required rate of return as 10% and expected rate of return as 15%, it means that the stock will perform above its peer stock in the market and the price will rise in the future.
