Lambda

Lambda is the 11th letter of the Greek alphabet. In finance, it is often used as a symbol for the risk-free rate of return. This is the rate of return that an investor can expect to earn on an investment that is free of risk. The risk-free rate is used as a benchmark for comparing the returns on other investments.

The risk-free rate is often estimated using the yield on U.S. Treasury bills. Treasury bills are short-term government debt securities that are considered to be very safe investments. The yield on Treasury bills is typically lower than the yield on other investments, such as stocks or bonds. This is because Treasury bills are considered to be less risky than other investments.

The risk-free rate is an important concept in finance because it is used to calculate the expected return on an investment. The expected return on an investment is the average return that an investor can expect to earn over a period of time. The expected return is calculated by taking the risk-free rate and adding a risk premium. The risk premium is a measure of the additional return that an investor expects to earn in order to compensate for the risk of the investment.

The risk-free rate is also used to calculate the present value of an investment. The present value of an investment is the value of the investment today, based on the expected future cash flows. The present value is calculated by discounting the future cash flows by the risk-free rate.
