This statement is correct because yield-to-maturity (YTM) is the annualized rate of return of a bond that assumes that all coupon payments are reinvested at the same rate until the bond matures. YTM takes into account the bond's current market price, par value, coupon rate, and time to maturity, and it calculates the compound interest earned on the reinvested coupons. Therefore, YTM reflects the total return of the bond, including both the interest income and the capital gain or loss.
