What leverage does
It multiplies gains and losses, but not equally — and that mismatch is exactly what knocks you out of the game.
The lopsided maths
If you lose 50%, you need a 100% gain just to get back to where you started. That mismatch exists even without leverage; leverage makes it worse.
With double leverage, a 25% market fall wipes out half your capital. To recover, you need what is left to grow by 100%.
That is why a leveraged portfolio can go to zero even in a market that eventually recovers in full. It was knocked out before the recovery arrived.
The margin call
When you hold positions with borrowed money and their value falls below a threshold, the lender demands extra cash on the spot. If you do not have it, they sell your position for you.
This always happens at the worst possible moment, because the threshold is hit precisely when prices are at their lowest.
That is the essential difference between a paper loss and a real one: without leverage, you decide when to sell; with leverage, someone else does.
Daily leveraged products
"2x" or "3x" ETFs reset every day. That means over longer periods they do not deliver double or triple the index's return.
In a market that bounces up and down without going anywhere, a product like this loses value continuously. The effect is called volatility decay.
These instruments are built for intraday trading. Holding them for months is a completely different use from the one they were designed for.
A 25% market fall
| Leverage | Your loss | Gain needed to recover |
|---|---|---|
| No leverage | −25% | +33% |
| 2x | −50% | +100% |
| 3x | −75% | +300% |
