Key Terms to Review (35)
Agency Bonds: Agency bonds are debt securities issued by government-affiliated organizations to raise capital for various public purposes. These bonds often carry lower interest rates compared to corporate bonds, as they are typically backed by the creditworthiness of the government, which makes them attractive to investors looking for relatively safer investment options.
Bond ratings: Bond ratings are evaluations provided by credit rating agencies that assess the creditworthiness of a bond issuer and the likelihood of default. These ratings help investors understand the risk associated with a bond, guiding their investment decisions based on the issuer's financial stability and ability to repay the debt. Ratings range from high-grade (low risk) to junk (high risk), influencing pricing and demand for the bonds in the market.
Build America Bonds: Build America Bonds are a type of taxable municipal bond introduced by the American Recovery and Reinvestment Act of 2009 to help state and local governments finance public projects. These bonds allow issuers to receive a federal subsidy, making them more attractive to investors, as they can offer higher yields compared to traditional tax-exempt bonds while helping to stimulate economic growth and job creation.
Call Risk: Call risk refers to the possibility that a bond issuer will redeem a callable bond before its maturity date, typically when interest rates decline. This can lead to investors receiving their principal back sooner than expected, which might force them to reinvest in lower-yielding securities. Understanding call risk is crucial for assessing the overall return and pricing of callable bonds, which have different characteristics compared to non-callable ones.
Convertible bonds: Convertible bonds are a type of debt security that can be converted into a predetermined number of the company's equity shares, usually at the discretion of the bondholder. This unique feature allows investors to benefit from potential price appreciation of the company's stock while still receiving regular interest payments. Convertible bonds combine characteristics of both debt and equity, providing flexibility and potentially lower borrowing costs for the issuing company.
Convexity: Convexity is a measure of the curvature in the relationship between bond prices and yields. It helps assess how the duration of a bond changes as interest rates change, indicating that the price of a bond will rise more when interest rates fall than it will decline when rates rise, providing a more nuanced understanding of bond price volatility.
Coupon rate: The coupon rate is the annual interest rate paid on a bond, expressed as a percentage of its face value. It is crucial for investors because it determines the periodic income they can expect from holding the bond until maturity. A higher coupon rate typically indicates a higher return for investors, while also reflecting the risk level associated with the bond issuer.
Credit risk: Credit risk refers to the possibility that a borrower may default on their financial obligations, failing to make required payments on loans or other credit arrangements. This risk is crucial for lenders, investors, and financial institutions as it can significantly impact returns on investment and overall financial stability. Understanding credit risk is essential for effective investment decision-making and portfolio management, as it influences the selection of assets and the expected return on investment.
Credit spread: A credit spread is the difference in yield between two bonds that have different credit qualities, reflecting the risk associated with the lower-rated bond. This concept helps investors assess the additional risk they take on when investing in bonds with lower credit ratings compared to safer, higher-rated options. Understanding credit spreads is essential for evaluating bond pricing, market conditions, and investment strategies.
Current yield: Current yield is a financial metric used to measure the annual income generated by a bond, expressed as a percentage of its current market price. It connects the bond's annual coupon payment to its current trading price, offering investors a quick way to gauge the return they might expect from purchasing the bond at that moment. This yield is particularly important for understanding how market conditions affect bond pricing and investor returns.
Default risk: Default risk is the possibility that a borrower will fail to meet their debt obligations, leading to a loss for lenders or investors. This risk is particularly significant in the context of bonds, as it directly affects their pricing and yields. Investors assess default risk when determining the creditworthiness of bond issuers, which can influence the interest rates they demand to compensate for the potential risk of non-payment.
Discount bonds: Discount bonds are debt securities that are sold for less than their face value, meaning investors can purchase them at a lower price than the amount they will receive at maturity. The difference between the purchase price and the face value represents the investor's earnings when the bond matures. These bonds do not typically pay periodic interest, so the return comes solely from the appreciation of the bond's value over time.
Duration: Duration is a measure of the sensitivity of a bond's price to changes in interest rates, expressed in years. It reflects the weighted average time until a bond's cash flows are received, and it serves as an important indicator for investors regarding interest rate risk. Essentially, the longer the duration, the more sensitive the bond's price is to fluctuations in interest rates, which can impact pricing and investment strategies.
Face value: Face value refers to the nominal or stated value of a bond, which is the amount the issuer agrees to pay back to the bondholder at maturity. This value is crucial as it determines the amount of interest payments the bondholder receives, typically expressed as a percentage of this face value. Understanding face value helps in grasping how bonds are priced and how their yields are calculated.
General Obligation Bonds: General obligation bonds are debt securities issued by municipalities, backed by the full faith and credit of the issuing authority. They are primarily funded through tax revenues, making them a reliable option for financing public projects like schools and infrastructure, as they promise to pay back bondholders with tax income.
High-yield bonds: High-yield bonds, also known as junk bonds, are bonds that carry a higher risk of default compared to investment-grade bonds but offer higher interest rates to compensate investors for taking on this risk. These bonds are typically issued by companies with lower credit ratings or those that are financially distressed, making them attractive to investors seeking greater returns in a low-interest-rate environment. The higher yields on these bonds come with increased volatility and credit risk, requiring careful consideration by investors.
Inflation Risk: Inflation risk refers to the potential for the value of investments to diminish due to rising prices, which erodes purchasing power over time. This risk is especially relevant when considering long-term investments, as the effects of inflation can significantly impact returns and the real value of money. Understanding inflation risk is crucial for effective financial planning, particularly in investment strategies, bond pricing, and retirement planning.
Interest rate risk: Interest rate risk is the potential for investment losses due to fluctuations in interest rates. When interest rates rise, the value of existing fixed-income securities, like bonds, typically falls, leading to potential losses for investors. This risk is particularly relevant for those investing in bonds and can impact overall investment strategies and goals.
Investment-grade bonds: Investment-grade bonds are debt securities rated as low risk by credit rating agencies, typically rated 'BBB-' or higher by Standard & Poor's and 'Baa3' or higher by Moody's. These ratings indicate that the issuer has a strong capacity to meet its financial commitments, making them a safer option for investors seeking reliable income. Investment-grade bonds play a crucial role in portfolios, providing stability and predictability in income while often being favored by conservative investors.
Liquidity risk: Liquidity risk is the potential difficulty an investor might face when trying to buy or sell an asset without causing a significant impact on its price. This risk is particularly relevant in the context of bonds, as it reflects how easily an investor can convert their bond holdings into cash. If a bond is not actively traded, it may be harder to sell quickly at a fair market price, thus exposing the investor to potential losses or delays.
Maturity Date: The maturity date is the specific date on which a bond's principal amount is due to be repaid to the bondholder. It marks the end of the bond's term and can influence its pricing, interest rate, and risk profile. Understanding the maturity date helps investors assess when they will receive their investment back and how interest rate changes may impact the bond's value before that date.
Modified duration: Modified duration is a measure of the sensitivity of a bond's price to changes in interest rates, expressed as the percentage change in price for a 1% change in yield. It provides insight into how much the price of a bond will fluctuate when interest rates rise or fall, reflecting both the bond's cash flow characteristics and its time to maturity.
Par value: Par value is the face value of a bond, which is the amount that will be repaid to the bondholder at maturity. It serves as a reference point for the pricing of bonds in the market and is critical in calculating interest payments, known as coupon payments, which are typically expressed as a percentage of the par value. Understanding par value helps investors evaluate the bond's return relative to its price in the market.
Premium bonds: Premium bonds are bonds that are sold at a price higher than their face value, meaning investors pay more upfront than they will receive back at maturity. This usually happens when the bond's coupon rate, or interest rate, is higher than current market rates, making it attractive to investors seeking higher returns. Premium bonds can provide steady income through regular interest payments, but they also come with the risk that their market value may decrease if interest rates rise.
Realized yield: Realized yield refers to the actual return on a bond investment, taking into account the cash flows received from interest payments and the capital gains or losses incurred when the bond is sold or matures. This yield provides a comprehensive view of the investor's total earnings over a specific period, reflecting not only the coupon payments but also the impact of market fluctuations and reinvestment rates on overall returns.
Reinvestment Risk: Reinvestment risk is the possibility that an investor will have to reinvest cash flows from an investment, such as bond interest payments or principal repayments, at a lower rate of return than the original investment. This is particularly important in the context of bonds, where changing interest rates can affect the returns on reinvested cash flows, leading to potentially lower overall yields.
Revenue Bonds: Revenue bonds are a type of municipal bond specifically used to finance income-producing projects and are repaid from the revenues generated by those projects. Unlike general obligation bonds, which are backed by the full faith and credit of the issuing municipality, revenue bonds rely solely on the income generated from specific projects, such as toll roads, bridges, or public utilities. This makes them a unique investment option that attracts investors looking for returns tied to particular revenue streams.
Savings bonds: Savings bonds are a type of debt security issued by the government to help finance national debt, providing a safe and low-risk investment option for individuals. They are designed to encourage saving among the public, often with features like low denominations and the ability to accumulate interest over time. Because they are backed by the full faith and credit of the government, they provide investors with a reliable means of saving.
Tax-exempt status: Tax-exempt status refers to a designation granted by the Internal Revenue Service (IRS) that allows certain organizations to be exempt from federal income taxes. This status is typically awarded to non-profit organizations, charities, and religious institutions, allowing them to operate without the burden of federal taxation on their income, which helps them allocate more resources towards their missions. Tax-exempt organizations must adhere to specific guidelines to maintain this status, including limitations on political activities and requirements for transparency in financial reporting.
Treasury bonds: Treasury bonds are long-term debt securities issued by the U.S. Department of the Treasury to finance government spending, with maturities typically ranging from 10 to 30 years. These bonds pay interest every six months and return the principal amount at maturity, making them a reliable investment option for individuals and institutions seeking safety and income.
Treasury Inflation-Protected Securities: Treasury Inflation-Protected Securities (TIPS) are U.S. government bonds specifically designed to protect investors from inflation. These securities adjust the principal value based on changes in the Consumer Price Index (CPI), ensuring that both interest payments and the bond's principal increase with inflation, thus preserving purchasing power over time.
Yield to Call: Yield to call is a financial metric used to measure the return an investor can expect to receive if a callable bond is redeemed by the issuer before its maturity date. This concept is essential for understanding the potential risks and rewards associated with investing in callable bonds, which have the option for the issuer to repurchase them at a predetermined price on specific dates. Investors consider yield to call in relation to the bond's coupon rate, market conditions, and interest rates when evaluating the overall attractiveness of the investment.
Yield to Maturity: Yield to maturity (YTM) is the total return anticipated on a bond if it is held until it matures. It reflects the bond's current market price, par value, coupon interest rate, and the number of years until maturity, providing a comprehensive measure of the expected yield for investors. YTM is crucial for evaluating the attractiveness of a bond compared to other investment opportunities and understanding how changes in interest rates affect bond prices.
Yield to Worst: Yield to worst is a measure used to assess the lowest potential yield an investor can receive on a bond without default. It takes into account the possibility of the bond being called or maturing early, which could result in a lower yield than what was initially expected. This concept is crucial for investors in evaluating the risks associated with bonds, particularly those with call provisions or varying maturity dates.
Zero-coupon bonds: Zero-coupon bonds are debt securities that do not pay periodic interest but are issued at a discount to their face value. Instead of receiving regular interest payments, investors receive a single payment at maturity that is equal to the bond's face value, making the difference between the purchase price and the face value the investor's return. This unique structure allows zero-coupon bonds to appeal to those who prefer a lump-sum payment in the future over regular income.
