Traditional Yield Measures

In the world of fixed income, a yield represents the annualised return an investor expects to earn from a security, expressed as a percentage of its price or face value. Traditional yield measures focus on cash‑flow based returns without adjusting for price volatility or credit risk, making them easy to calculate and widely used in advisory practice.

These measures are especially important for Indian investors because most retail bond products – such as government securities, corporate bonds and tax‑free bonds – are quoted in terms of yields. SEBI’s Investment Adviser guidelines require advisers to disclose the yield assumptions used when recommending a debt instrument.

For the NISM Series X‑A exam, you will be asked to compute yields, compare them across securities, and spot typical pitfalls like mixing up current yield with yield to maturity. Understanding the underlying assumptions of each measure will help you answer scenario‑based questions accurately.

Current Yield measures the income component of a bond relative to its current market price. It is calculated by dividing the annual coupon payment by the market price and multiplying by 100 to express it as a percent.

This measure is useful for investors who are primarily interested in the cash‑flow aspect, such as retirees seeking steady income. However, it does not account for any price appreciation or depreciation that will occur if the bond is held to maturity.

On the NISM exam, Current Yield questions often provide the coupon amount, market price and ask you to compute the percentage. Watch out for coupons quoted semi‑annually – you must annualise them before using the formula.

Yield to Maturity is the internal rate of return earned if the bond is held until it matures, assuming all coupons are reinvested at the same rate. The exact YTM requires solving a present‑value equation, which is iterative. NISM provides an approved approximation that is sufficient for most exam scenarios.

The approximation adds the annual coupon to the average annual capital gain (or loss) and divides by the average of the face value and the purchase price. The result is then annualised and expressed as a percent.

Remember: the approximation is acceptable only when the question explicitly asks for “approximate YTM” or provides limited data. If the exam expects a precise YTM, you would need a financial calculator – which is beyond the scope of the paper.

Many Indian corporate bonds are callable, meaning the issuer can redeem them before maturity at a predetermined call price. Yield to Call is calculated similarly to YTM but uses the call price and the years until the call date.

The NISM syllabus provides an approximation identical in form to the YTM formula, substituting the call price (CP) for the face value. This helps advisers assess the worst‑case return if the bond is called early.

Yield to Worst is the lowest yield among YTM, YTC and any other optional redemption yields. It is the most conservative figure and is the one SEBI expects advisers to disclose when presenting callable bonds.

Holding Period Return captures the total return earned over the actual holding period, which may be shorter than the bond’s full term. It includes both coupon income received and any price change between purchase and sale.

The formula adds the income (I) to the capital gain (P1‑P0) and divides by the initial purchase price (P0). This measure is useful when an adviser recommends selling a bond before maturity.

On the exam, HPR questions often give you the purchase price, sale price and total coupons received during the holding period. Be careful to annualise the result only if the question explicitly asks for an annualised return.

Bond prices and yields move inversely: when market prices rise, yields fall, and vice‑versa. This relationship is central to advising clients who react to interest‑rate movements. For example, a decline in RBI policy rates will push existing bond prices up, reducing their yields.

Advisers use the appropriate yield measure based on the client’s horizon. Income‑focused clients may care more about Current Yield, while long‑term investors need YTM or YTW to gauge total return. SEBI mandates that advisers disclose the Yield to Worst for callable bonds, ensuring clients understand the most conservative outcome.

In practice, you will compare yields across different issuers, sectors and credit ratings. A higher Yield to Maturity does not automatically mean a better investment; it may reflect higher credit risk. Balancing yield with credit quality and duration is the hallmark of a prudent advisory recommendation.
