In a rising market, leverage looks like genius. You put in one, you control four, the four goes up, and your return on the one is spectacular. Everyone around you is doing it, and for a while, everyone is right. This is the most dangerous moment in any investor’s life.
The math that nobody prints in the brochure
Leverage is symmetric in the numbers and asymmetric in real life. On the way up it multiplies gains. On the way down it multiplies losses — but with a cruel twist: the losses can arrive as a margin call or a refinancing at exactly the moment credit dries up. The market does not need to collapse to ruin a leveraged buyer. It only needs to pause while a payment is due.
A cash buyer who is wrong about timing waits. A leveraged buyer who is wrong about timing can be forced to sell into the very weakness they were waiting out. Same asset, same thesis, completely different outcome — and the only difference is the debt.
Leverage does not change whether you are right. It changes whether you get to be around long enough to find out.
The friction beneath the numbers
There is a reason my tradition treats debt with such seriousness, and interest-bearing debt as something to avoid entirely. Strip away the theology and a purely practical wisdom remains: debt transfers your future peace to a lender. It converts an asset you own into an obligation that owns you. The borrower, the old teaching goes, is servant to the lender — and servitude is a strange foundation for a life you are trying to build freely.
I am not against every use of finance. I am against the casual, ambient leverage that has become normal here — the assumption that of course you gear up, because everyone does, because the market only goes one way. Markets that only go one way are stories we tell ourselves at the top.
Use the least leverage the plan can bear, not the most the bank will allow. Structure it so that being wrong about timing is survivable. And keep enough dry powder that a downturn is an opportunity you can act on, rather than an emergency you are trapped inside. That is not timidity. It is staying in the game.
