Leverage
Trading with borrowed money to amplify position size.
Leverage means controlling more market exposure than the cash in the account, by borrowing from the broker. It multiplies both gains and losses, and it introduces the one outcome unleveraged investing cannot produce: losing more than you can recover from, quickly.
Most catastrophic retail trading losses involve leverage. An unleveraged, long-only strategy has a natural floor: a position can at worst go to zero, and diversified positions do not all go to zero together. With leverage, a single sharp move can end the account.
