The bond market rewards a little discipline and punishes a little carelessness, and many investing mistakes tend to follow the same predictable patterns. Here's what to watch for.
1. Chasing yield without checking the rating first
A bond offering 13% next to one offering 8% isn't automatically the better deal. It's usually compensating you for taking on more credit risk. Decide your minimum acceptable rating before you start browsing yields, so a tempting coupon doesn't quietly pull you into a rating band you weren't actually comfortable with.
2. Ignoring tenure mismatch
A 10-year bond isn't a bad choice. It's the wrong choice if you know you'll need the capital back in 18 months and don't want to rely on selling into the secondary market at an uncertain price. Match the bond's tenure to your actual investment horizon, not just to whichever bond has the most attractive headline yield.
3. Assuming “bond,” “debenture” and “NCD” tells you everything
These terms describe the instrument, but they don't automatically tell you how well protected you are if the issuer runs into trouble. Secured bonds are backed by specific issuer assets pledged as collateral, similar to how a car loan is backed by the car. Unsecured bonds or debentures carry no such backing. Always check this explicitly rather than assuming.
4. Not checking liquidity before assuming you can exit anytime
Bonds are tradable, but that doesn't mean every bond trades actively. A bond with thin trading volume can be genuinely hard to sell at a fair price exactly when you need to. If there's any chance you'll exit before maturity, check the bond's typical trading activity on the exchange first.
5. Overlooking call risk
A callable bond lets the issuer redeem it early, usually when interest rates fall and refinancing gets cheaper for them. If you bought it expecting a fixed income stream over its full stated maturity, an early call can shorten your actual holding period and realised return without warning. Check whether a bond is callable before assuming its stated maturity is guaranteed.
6. Being surprised by TDS
New investors sometimes assume the quoted yield is exactly what lands in their bank account. In reality, Tax Deducted at Source is deducted from interest payments before you receive them. While this amount can be claimed as a credit against your final tax liability, it can still be surprising if you weren't expecting it. Capital gains, by contrast, generally arrive without TDS and are reported when you file your return.
7. Putting the entire fixed-income allocation into one bond
Just as you wouldn't put your entire equity portfolio into a single stock, concentrating your entire bond allocation in one issuer means a single downgrade or default can have an outsized impact. Because many bonds are available in relatively small investment sizes, diversification across issuers, maturities and credit ratings is often easier than investors realise.
8. Confusing coupon with yield
The coupon rate is fixed at issuance and never changes. Yield to Maturity (YTM), however, reflects the price you actually paid for the bond, which may differ from its face value if you're buying in the secondary market. As a result, your actual return can be higher or lower than the coupon rate. Always compare YTM rather than coupon rate when evaluating bonds.
The fix for all eight
None of these mistakes require sophisticated analysis to avoid. They simply require you to look at credit rating, yield, tenure, liquidity, security type and call features together, rather than focusing on any one number in isolation.
