Yield for a Portfolio (Internal Rate of Return)

Computed by determining the cash flows for the portfolio and determining the interest rate that will make the present value of the cash flows equal to the market value of the portfolio. The yield for a portfolio of bonds is not simply the average or weighted average of the yield to maturity of the individual bond issues in the portfolio. However, a good approximation to the yield for a portfolio can be obtained by using duration to weight the yield to maturity of the individual bonds in the portfolio.
