6.7.1 Bond Quotation Systems

Understanding how to read bond quotes and ratings is essential for any investor involved in fixed-income securities. This section delves into the systems used for quoting bonds, focusing on price and yield information, and the conventions used such as clean and dirty pricing.

Price and Yield Quotes

Price Quotes

Bond prices are typically quoted as a percentage of their face value or par value. A bond trading at par is quoted at 100.00, whereas a bond trading at a premium or discount is quoted above or below 100, respectively. For example, a quoted price of 105.00 means the bond is trading at 105% of its par value, indicating a premium.

Key Points:

• Face Value: The amount the issuer agrees to pay back at maturity, usually $1,000.
• Quoted Price: Expressed as a percentage of the face value.
• Premium and Discount: Prices above 100 indicate a premium; prices below 100 indicate a discount.

Yield Quotes

Yield represents the return an investor can expect to earn if the bond is held until maturity. Yield quotes provide insight into the bond’s performance relative to its price.

Types of Yield:

• Nominal Yield: Fixed percentage of the bond’s face value, reflecting the coupon rate.
• Current Yield: Calculated by dividing the annual coupon payments by the bond’s current market price.
• Yield to Maturity (YTM): The total return anticipated on a bond if held to maturity, accounting for all coupon payments and the difference between the purchase price and face value.

The Relationship Between Price and Yield

Bond prices and yields have an inverse relationship. As prices rise, yields fall and vice versa. This relationship helps investors assess the potential costs and benefits of buying a bond at a given price.

Pricing Conventions

In bond markets, it’s crucial to distinguish between different pricing conventions, primarily clean and dirty pricing.

Clean Pricing

Clean pricing quotes the bond’s price without including the accrued interest since the last coupon payment. This type of pricing is useful for comparing the intrinsic value of different bonds.

Formula:

Dirty Pricing (Full Price or Invoice Price)

Dirty pricing includes the accrued interest in the bond’s quoted price. This reflects the actual amount the buyer pays when purchasing the bond between coupon payment dates.

Formula:

Accrued interest is calculated based on the number of days since the last coupon payment and the expected coupon amount. Using dirty pricing, investors can better account for the complete transaction cost.

Examples:

Considering a bond with a 5% annual coupon and face value of $1,000, the accrued interest would be calculated from the last coupon date to the current date based on the coupon period (semi-annual, quarterly, etc.).
