6.10 : リスクプレミアム

The risk premium is the additional return an investor requires, to invest in a riskier asset than a risk-free investment. It is a compensation for the uncertainty and potential volatility for the investor.

Let us consider an investor, John.

John is evaluating an investment as a founder in a startup tech company, which is considered riskier than a government bond.

Assuming on a ten-year United States Treasury bond, which is considered a risk-free investment, the yield is about two percent per year.

However, the startup is in a competitive and rapidly evolving market, which introduces a higher risk of loss and the possibility of significant gains.

John determines that he would only invest in the startup if he could potentially earn an annual return of at least eight percent.

Here, the risk premium John requires is six percent.

This premium reflects the additional risk John is willing to take beyond the safe return of the treasury bond. It includes compensation for the startup's market risk and the uncertainty of its technology being adopted in the industry.

Such calculations are essential for investors like John to make informed decisions about where to allocate their investments.
