In the capital asset pricing model CAPM , RRR can be calculated using the beta of a security, or risk coefficient, as well as the excess return that investing in the stock pays over a risk-free rate called the equity risk premium. Assume the following:. Let's say Company A has a beta of 1. Company B has a beta of 0. Thus, an investor evaluating the merits of investing in Company A versus Company B would require a significantly higher rate of return from Company A because of its much higher beta.
Although the required rate of return is used in capital budgeting projects, RRR is not the same level of return that's needed to cover the cost of capital. The cost of capital is the minimum return needed to cover the cost of debt and equity issuance to raise funds for the project. The cost of capital is the lowest return needed to account for the capital structure. The RRR should always be higher than the cost of capital.
The RRR calculation does not factor in inflation expectations since rising prices erode investment gains. However, inflation expectations are subjective and can be wrong. Also, the RRR will vary between investors with different risk tolerance levels. A retiree will have a lower risk tolerance than an investor who recently graduated college. As a result, the RRR is a subjective rate of return. RRR does not factor in the liquidity of an investment. If an investment can't be sold for a period of time, the security will likely carry a higher risk than one that's more liquid.
Also, comparing stocks in different industries can be difficult since the risk or beta will be different. As with any financial ratio or metric, it's best to utilize multiple ratios in your analysis when considering investment opportunities. Financial Analysis. Financial Ratios. Risk Management.

There is an inverse relationship between the required return and the stock price investors assign to a stock. The required return might rise if the risk premium or the risk-free rate increases. For instance, the risk premium might go up for a company if one of its top managers resigns or if the company suddenly decides to lower its dividend payments. And the risk-free rate will increase if interest rates rise.
So, changes in interest rates impact the theoretical value of companies and their shares — basically, a share's fair value is its projected future cash flows discounted to the present using the investor's required rate of return. If interest rates fall and everything else is held constant, share value should rise. That's why the market generally cheers when the U. Federal Reserve announces a rate cut.
Conversely, if the Fed raises rates holding everything else constant , then share values are likely to fall. Interest rates impact a company's operations too. Any increase in the interest rates that it pays will raise its cost of capital. Therefore, a company has to work harder to generate higher returns in a high-interest environment. Otherwise, the bloated interest expense will eat away at its profits. Lower profits, lower cash inflows, and a higher required rate of return for investors all translate into depressed fair value for the company's stock.
Additionally, if interest rate costs shoot up to such a level that the company has problems paying off its debt , then its survival may be threatened. In that case, investors will demand an even higher risk premium. As a result, the fair value will fall even further. Finally, high-interest rates normally go hand-in-hand with a sluggish economy. They prevent people from buying things and companies from investing in growth opportunities.
As a result, sales and profits drop, as do share prices. In financial theory, valuation begins with a simple question: if you put money into this company, what are the chances you will get a better return than if you invest in something else?
