Leverage
Using borrowed money to increase the size of your position.
Leverage multiplies gains and losses equally, but the consequences are not symmetric. At 5x leverage, a 20% fall in the asset wipes out 100% of your money, while the asset itself is still worth four fifths of what it was.
It does not change your expected return. It changes the probability that you survive long enough to receive it.
Why the debt is the engine
Put in 30, borrow 70, secure the loan against the company you are buying. A 30% rise in the business doubles your money. The same arithmetic works in reverse, which is why buyouts fail loudly.
It is the single most common cause of total, unrecoverable loss among otherwise competent investors.
Believing that being right about direction is enough. With leverage, you must also be right about timing.
