The Three Habits That Kill Most Portfolios
Three investors who found out. One who did not.
Three people who were genuinely good at investing — a bond manager, an engineer, a realtor — and lost everything anyway. Plus one man who survived all three. No advice. Just what they had in common.
- Real market history — 1994, 2000, 2008 — sourced, not simplified.
- Decisions from the inside — why each mistake felt like experience.
- One question to ask before every decision.

The one question in the book
What would this cost me if I turn out to be wrong?
The only thing the survivor asked before every decision — and the one thing the other three never did.

-
Real and sourced
The markets in these pages are real: 1994, 2000, 2008. Every figure comes from the record, and the sources are listed at the back. Nothing is simplified into something it was not.
-
Understanding, not tips
We name the habit only at the end of each story, on purpose. A label you can repeat is worth far less than a mistake you have watched happen from the inside.
-
Yours, not ours
You will not find a ticker, a sector or a recommendation anywhere. The point is that you understand enough to make your own decisions — so that is the only thing we try to give you.
