Two Ways to Own Bonds
You can own bonds in two fundamentally different ways — and the difference matters more than most investors realize:
1
Individual BondsPredictable
Buy a specific Treasury or corporate bond directly. You know exactly when it matures and what it pays. At maturity, you receive the full face value back — regardless of what interest rates did in the interim.
2
Bond Funds / ETFsFlexible
A fund that owns hundreds of bonds. You get diversification and instant liquidity, but there is no fixed maturity date — the fund never "matures" and never returns par. Price fluctuates with interest rates indefinitely.
The ETF vs individual bond distinction is especially important for retirees who need predictable income. For most accumulation-phase investors, the simplicity of ETFs wins. For those in or near retirement, knowing exactly when money returns can be critical.

TLT's 0.15% expense ratio is modest, but its ~17-year duration is what makes it high risk. Meanwhile BND and AGG at 0.03% are among the cheapest ways to own the broad bond market.
Bond Ladders — Individual Bonds in Practice
A bond ladder staggers maturities so you always have bonds maturing soon — providing liquidity and reinvestment opportunities without having to sell into a volatile market.
Example: $50,000 in a 5-Year Treasury Ladder
1
$10,000 in 1-year TreasuryMatures 2025
2
$10,000 in 2-year TreasuryMatures 2026
3
$10,000 in 3-year TreasuryMatures 2027
4
$10,000 in 4-year TreasuryMatures 2028
5
$10,000 in 5-year TreasuryMatures 2029
When the 1-year matures, reinvest in a new 5-year (now maturing 2030). The ladder "rolls forward" — you're always earning longer-duration rates while maintaining annual liquidity. TreasuryDirect.gov lets you buy Treasuries directly with no broker fee.

Recommendation: ETFs for the accumulation phase — simplicity wins when you're growing wealth. Bond ladders for retirement income — predictability wins when you need to live off your portfolio. Use TreasuryDirect.gov for Treasuries with zero broker fees.
Common Bond ETF Mistakes
Even experienced investors make these errors with bond funds. Know them before you invest:
1
Buying TLT for yield
TLT has a duration of ~17 years. In rising rate environments it can fall 30%+. Many investors buy it thinking "safe US Treasuries" without understanding that duration, not credit quality, is the risk. TLT is a high-volatility instrument.
2
Ignoring duration when buying
"Bond fund" does not mean safe. SHY (1-3 year) and TLT (20+ year) are both Treasury ETFs — but their price sensitivity to rate changes is vastly different. Always check duration before buying any bond fund.
3
Holding high-yield in a crisis
In recessions, HYG correlates far more with the stock market than investment-grade bonds — you lose the diversification benefit precisely when you need it most. High-yield bonds are equity-like in drawdowns.
4
Forgetting about expense ratios
The difference between 0.03% (BND) and 0.75% (some active bond funds) compounds significantly over 30 years. On a $100,000 bond allocation at 4% gross yield, that 0.72% gap costs you roughly $30,000+ over a career.

Key takeaways from Lesson 7
Bond ETFs never return par value — price fluctuates indefinitely with interest rates.
Bond ladders stagger maturities, providing annual liquidity and known return-of-principal dates.
ETFs win on simplicity and diversification; ladders win on predictability for retirement income.
TLT is not a conservative safe-haven — its ~17-year duration makes it highly rate-sensitive.
High-yield ETFs (HYG) correlate with stocks during crises — they don't hedge equity risk when it matters most.
BND and AGG at 0.03% are the low-cost bedrock options for broad bond market exposure.
