1. “Leverage is what kills you”
Buffett repeatedly warns that leverage turns ordinary mistakes into disasters.
“If you’re smart, you don’t need it; if you’re dumb, you shouldn’t be using it.”
His point: even good investors are sometimes wrong. With leverage, being wrong doesn’t just hurt—it can wipe you out.
2. Survival > Returns
Buffett prioritizes staying in the game over maximizing returns.
He often emphasizes:
- You don’t need to swing for the fences
- Avoiding ruin is more important than making extra profit
Leverage introduces:
- Margin calls
- Forced liquidation at the worst time
- Loss of control over timing
That’s exactly the opposite of how he invests (long-term, patient, no forced selling).
3. “Never risk what you have and need…”
One of his most famous principles:
“Never risk what you have and need for what you don’t have and don’t need.”
Leverage violates this because:
- You’re borrowing money
- You can lose more than your initial capital
- You’re putting your financial stability at risk for extra upside
4. Even professionals blow up with leverage
Buffett has pointed out that:
- Long-Term Capital Management (LTCM) collapsed due to leverage
- Many hedge funds fail not because of bad ideas—but because of too much leverage
His takeaway: intelligence doesn’t protect you from leverage risk.
