====== Fixed-Income Securities ======
Fixed-Income Securities (also known as '[[Bonds]]' or '[[Debt Securities]]') are essentially a loan you, the investor, make to a corporation or government. Think of it as being the bank for a big organization. In return for your cash upfront, the borrower (the `[[issuer]]`) promises to pay you `[[interest]]` payments over a set period. These payments are typically at a fixed rate, which is why it's called "fixed income"—you know exactly how much cash you'll receive and when. At the very end of the loan's term, on what's called the `[[maturity date]]`, the issuer repays your original loan amount, known as the `[[principal]]`. For an investor, fixed-income securities are the workhorses of a portfolio, prized for their predictability and relative safety compared to the rollercoaster ride that can be the stock market. They provide a steady stream of income and are a cornerstone for preserving capital.
===== How Do Fixed-Income Securities Work? =====
At its heart, a fixed-income security is a simple contract. An issuer needs money to fund projects, like a company building a new factory or a city building a new school. Instead of going to a bank, they borrow from the public by issuing bonds.
==== The Key Players: Issuer and Investor ====
There are two main parties in this transaction:
  * **The Issuer:** This is the entity borrowing the money. It can be a national government, a local municipality, or a public corporation. They get the cash they need for their operations or expansion.
  * **The Investor (or Bondholder):** This is you. By purchasing the bond, you become a lender. You give your capital to the issuer in exchange for the promise of receiving regular interest payments and the full return of your principal at maturity.
==== The Core Components ====
Every bond is defined by three key features:
  * **Par Value (or Face Value):** This is the amount of the loan that will be repaid to the investor at maturity. While bonds can trade on the open market for more or less than this amount, the par value is the fixed sum you're entitled to at the end. It's most commonly $1,000 for corporate bonds.
  * **Coupon Rate:** This is the fixed annual interest rate paid on the bond's par value. For example, a $1,000 bond with a 5% coupon rate will pay the investor $50 in interest each year (5% x $1,000). This payment is often made in two semi-annual installments.
  * **Maturity:** This is the date when the bond "expires," and the issuer must repay the par value to the bondholder. Maturities can range from very short-term (less than a year) to very long-term (30 years or more).
===== Types of Fixed-Income Securities =====
The world of fixed-income is vast, but most securities fall into two main camps based on who is doing the borrowing.
==== Government Bonds ====
These are issued by governments and are generally considered the safest category of bonds because they are backed by the taxing power of the issuing government.
  * **[[Treasury Bonds]] (T-Bonds):** Issued by the U.S. federal government to fund its debt. Because the U.S. government has never defaulted on its debt, these are seen as one of the safest investments on the planet. This category also includes shorter-term T-Notes and T-Bills.
  * **[[Municipal Bonds]] ("Munis"):** Issued by states, cities, and other local government entities to fund public projects. Their superpower is that the interest income is often exempt from federal taxes, and sometimes state and local taxes, too, making them especially attractive to investors in high tax brackets.
==== Corporate Bonds ====
These are issued by companies to raise money for things like business expansion or research. They are riskier than government bonds because companies can, and do, go out of business. To compensate for this higher risk, corporate bonds almost always offer a higher coupon rate than a government bond with the same maturity.
===== The Value Investor's Perspective on Fixed-Income =====
While stocks often steal the limelight with tales of spectacular growth, the true value investor understands the indispensable role of fixed-income.
==== The Role of Safety and Predictability ====
Legendary value investor [[Benjamin Graham]] described a portfolio as a blend of defensive (bonds) and enterprising (stocks) components. Fixed-income securities are the ultimate defensive asset. They provide a predictable stream of `[[cash flow]]` and act as a stabilizing anchor during stock market storms. While `[[stocks]]` are for growing your wealth, bonds are primarily for //preserving// it. Their job is to ensure that a portion of your capital is safe and earning a steady, reliable return, no matter what Wall Street is doing.
==== When Bonds Get Interesting: Price vs. Value ====
Here’s a crucial concept: bond prices and `[[interest rates]]` move in opposite directions. If you buy a bond with a 3% coupon, and a year later the central bank raises interest rates so that new bonds are being issued at 5%, your 3% bond suddenly looks less appealing. If you wanted to sell it, you'd have to do so at a discount to its par value.
This is where a value investor's ears perk up. Sometimes, a perfectly good bond from a financially sound company might trade at a discount simply due to market-wide interest rate changes or irrational fear. A value investor can then buy this debt for less than its `[[intrinsic value]]`, lock in a higher effective yield (known as `[[yield to maturity]]`), and be repaid the full par value at maturity. It's the same principle as buying a dollar for fifty cents, applied to the world of debt.
===== Risks to Consider =====
"Safe" doesn't mean risk-free. Even the sturdiest investments carry some risks that every investor must understand.
==== Interest Rate Risk ====
As mentioned above, this is the risk that a rise in general interest rates will cause the market price of your bond to fall. This is most relevant if you plan to sell your bond before it matures. If you hold it to maturity, you'll still get the full par value back, but you'll have endured an `[[opportunity cost]]` by holding a lower-yielding asset.
==== Inflation Risk ====
This is the risk that the rate of `[[inflation]]` will outpace your bond's fixed coupon rate, eroding the purchasing power of your investment returns. A 4% annual return feels great when inflation is 2%, but it means you're losing real value if inflation jumps to 6%.
==== Credit Risk (or Default Risk) ====
This is the most serious risk: the chance that the issuer will be unable to make its interest payments or repay your principal. If the company or municipality goes bankrupt, you could lose your entire investment. To help investors assess this risk, agencies like Moody's and Standard & Poor's provide `[[credit ratings]]`. A top-tier "AAA" rating signifies very low risk, while a "C" or "D" (junk bond) rating signals a high probability of default—but also comes with a much higher interest rate to tempt risk-takers.
