What is "Yield to Maturity (YTM)"?

Yield to Maturity is a measure of the return on a bond that assumes the bond will be held until maturity. It is calculated as the rate of return that equates the bond's price to its expected cash flows, taking into account the bond's coupon rate, its face value, the length of time until maturity, and the current market interest rate. It is typically expressed as a percentage and is used to compare the relative value of different bonds with different maturities and coupon rates.

What are the formulae for calculating YTM?

There are several ways to calculate the YTM (YTM) of a bond, but some common formulae include:

1. The bond pricing formula:

YTM = (C + (F - P) / N) / ((F + P) / 2)

where C is the annual coupon payment, F is the face value of the bond, P is the bond's price, and N is the number of years to maturity.

2. The discounted cash flow formula:

YTM = (C / P) + (F / P - 1) / N

where C is the annual coupon payment, F is the face value of the bond, P is the bond's price, and N is the number of years to maturity.

3. The modified duration formula:

YTM = (-1 / D) * (1 / P) * (dP / dy)

where D is the modified duration, P is the bond's price, and dP/dy is the derivative of the bond's price with respect to yield.

4. Newton Raphson Method

The yield to maturity (YTM) formula for the Newton-Raphson method is an iterative numerical process for finding the yield on a bond that discounts the bond's future cash flows to the present value. It is expressed as follows:

Yield to Maturity (YTM) = Yield(n-1) - (Price(Yield(n-1)) - Bond Price)/Duration(Yield(n-1))

where:

Yield(n-1) is the estimated yield from the previous iteration.

Price(Yield(n-1)) is the present value of the bond's cash flows calculated using the estimated yield from the previous iteration.

Bond Price is the market price of the bond.

Duration(Yield(n-1)) is the modified duration calculated using the estimated yield from the previous iteration.

The process continues until the estimated yield converges to a specific value.

5. Iterative trial and error method.

The iterative trial and error method for calculating yield to maturity (YTM) involves iteratively guessing a rate and using that rate to calculate the present value of the bond's cash flows, until the present value of the cash flows matches the bond's market price. The formula for this method can be expressed as follows:

Let "r" be the estimated yield.

Yield to Maturity (YTM) = r - (Price(r) - Bond Price) / Price(r) * (1 + r)^n

where:

Price(r) is the present value of the bond's cash flows calculated using the estimated yield "r".

Bond Price is the market price of the bond.

n is the number of periods until the bond matures.

The process continues until the estimated yield converges to a specific value.

Note that these are some common ways to calculate YTM but the actual calculation may vary depending on the bond and the information that is available.

Difference between YTM and coupon rate

The coupon rate is the annual interest rate that a bond pays to its bondholders, while YTM (YTM) is the total return anticipated on a bond IF the bond is held until maturity.

Coupon rate is a fixed percentage of the bond's face value, and it remains constant throughout the bond's life. For example, if a bond has a coupon rate of 5% and a face value of $1,000, the bond will pay $50 in interest annually.

YTM, on the other hand, takes into account not just the coupon rate, but also the bond's price, the time to maturity, and the current market interest rates. YTM is an indicator of the bond's expected total return if held to maturity. A bond with a lower coupon rate may have a higher YTM if its price is discounted, or if market interest rates have dropped, making the bond more attractive.

In summary, the coupon rate is the annual interest payment on a bond, while the YTM is the total return an investor can expect if they hold the bond until maturity.

----------------------------------------------------------------------------------------

Now, the question arises suppose if the bond is not held until maturity, will the yield to maturity metrics works?

The answer is NO.

YTM assumes that the bond is held until maturity and calculates the total return on the investment, taking into account both coupon payments and the return of principal. If a bond is not held until maturity, the actual yield realized may be different from the YTM, as the bond's price may fluctuate in the secondary market. In this case, the actual yield would be based on the purchase price of the bond and the coupon payments received, not the YTM. It's important for investors to consider both the YTM and market conditions when making investment decisions, especially if they plan on selling their bonds before maturity.

Is YTM an anticipated return or actual return?

YTM (YTM) is an anticipated return on a bond, assuming it is held until maturity.

Anticipated return and actual return refer to the estimated or expected return on an investment versus the actual return realized.

Anticipated return is a projection or estimate of what an investor can expect to earn on an investment based on various factors such as market trends, historical performance, and individual circumstances. It represents the expected outcome and serves as a guide for investment decisions.

Actual return, on the other hand, is the actual amount of money earned on an investment after taking into account all relevant factors such as market fluctuations, fees, taxes, and inflation. It is the actual outcome and may differ from the anticipated return due to unforeseen events or changes in market conditions.

In summary, the difference between anticipated return and actual return is that the former is an estimate or projection, while the latter is the actual performance of an investment.

Will YTM be useful if the bond is not traded in the market?

YTM (YTM) is typically used as a measure of the expected return on a bond that is traded in the market. It is based on the bond's price, coupon rate, time to maturity, and the current market interest rates. If a bond is not traded in the market, it may not have a readily observable market price, making it difficult to calculate its YTM.

In the case of a bond that is not traded in the market, it might be more appropriate to use the coupon rate as a measure of the bond's expected return. The coupon rate is the annual interest rate that the bond pays to its bondholders, and it is fixed and known.

That being said, if the bond is privately held, the YTM can still be calculated, as long as the cash flows, maturity and face value of the bond are known. It just means that the YTM will be an estimate and not an observable market value.

How to compare two different bonds using YTM?

To compare two different bonds using YTM, you will need to calculate the YTM for each bond and then compare the results. You can use the bond's price, its face value, the coupon rate, and the time to maturity to calculate the YTM. Then, you can compare the YTM of each bond to see which one offers a higher rate of return. Keep in mind that other factors, such as creditworthiness of the issuer and the bond's duration, may also affect the bond's risk and return.

How does the current market interest rate affect the bond's YTM?

The current market interest rate affects the bond's YTM in the following ways:

1. Inverse relationship: As the market interest rate increases, the bond's YTM decreases. This is because when the market interest rate is high, investors can earn a higher return on other investments, making the bond less attractive.

2. Price of the bond: The price of the bond is inversely related to the YTM. As the market interest rate increases, the price of the bond decreases and vice versa.

3. Credit risk: The credit risk of the bond issuer also affects the bond's YTM. A bond issued by a company with a lower credit rating will have a higher YTM as investors will demand a higher return for the added risk.

4. Maturity: The maturity of the bond also affects the bond's YTM. Bonds with longer maturities will have a higher YTM than bonds with shorter maturities as investors will demand a higher return for the added risk of holding the bond for a longer period of time.

Overall, the current market interest rate is one of the key factors that affect the bond's YTM, as it can impact the price, credit risk, and maturity of the bond.

How does the coupon rate affect the bond's YTM?

The coupon rate is the annual interest rate that a bond pays to its bondholders, while the YTM (YTM) is the rate of return an investor would receive if they held the bond until maturity. In general, the coupon rate and YTM have an inverse relationship, meaning that as the coupon rate increases, the YTM decreases and vice versa. This is because a higher coupon rate means that the bond is paying more interest to the bondholder, which makes the bond more attractive to investors and thus leads to a lower yield. Conversely, a lower coupon rate means that the bond is paying less interest, making it less attractive to investors and resulting in a higher yield.

Can I use YTM for equity?

No, YTM is a measure of the return on a bond. It is not applicable to equity, which refers to ownership in a company and does not have a set maturity date or coupon rate. Instead, measures of return for equity include dividends and capital gains.

Can I use YTM for debentures?

Yes, YTM can be used for debentures

Can I use YTM for preference shares?

Yes, you can use YTM for preference shares. YTM (YTM) is a measure of the return on an investment, calculated as the annual rate of return assuming the investment is held until maturity. It is commonly used for bonds, but can also be applied to preference shares. However, it is important to note that preference shares have different characteristics and risk profiles compared to bonds, so the YTM calculation may not be directly comparable.

Why do YTM assumes that all the coupon payments are reinvested at the same rate?

YTM assumes that all coupon payments are reinvested at the same rate because it is a measure of the overall return on an investment, taking into account both the current market price of the bond and the future cash flows it will generate through coupon payments and the return of principal. By assuming that all coupon payments are reinvested at the same rate, it allows for a consistent and accurate calculation of the overall return on the investment, as well as a fair comparison between different bonds with different coupon rates and maturities. Additionally, assuming that all coupon payments are reinvested at the same rate also simplifies the calculation process and makes it more easily understandable for investors.

Is YTM the only metric to calculate expected rate of return?

No, YTM is not the only metric to calculate expected rate of return. Other metrics that can be used include current yield, total return, and internal rate of return. These metrics may provide different perspectives on the expected rate of return for an investment.
