answer:Bond yield refers to the rate of return an investor can expect on a bond. In other words, it reflects the interest earned on a bond, which is usually expressed as an annual percentage rate. Bond yields change with movements in interest rates, the creditworthiness of the bond issuer, and with changes in the general economic environment. Many investors pay close attention to bond yields because they are a key indicator of the bond's expected return on investment, its risk, and its value relative to other investment options. There are a few common ways to calculate bond yield. The most widely used method is the yield to maturity (YTM), which calculates the total interest the bond will earn if it is held until its maturity date. This calculation takes into account the bond's current market price, its face value, its coupon rate, and the length of time until it matures. Another method is current yield, which measures the bond's annual return based on its current market price and its coupon payments. Understanding the differences between these methods and how to interpret their results can help investors make more informed decisions about their bond investments.
