Catch a falling knife
Meaning
To attempt to profit from a rapidly declining asset, or more broadly, to get involved in a situation that is deteriorating quickly and is likely to cause harm.
Origin
The vivid and instantly understood image of a literal falling knife, with its inherent danger and likelihood of inflicting harm, gave birth to this powerful financial metaphor. In the high-stakes, fast-paced world of early 20th-century stock markets, investors were constantly on the lookout for a bargain. When a stock price began to plummet dramatically, some saw it as an irresistible opportunity to 'buy low.' However, experienced traders quickly observed the perilous outcome of such gambles, warning against the futility and peril of attempting to halt something in rapid, uncontrolled descent. The phrase crystallized the wisdom that intervening in a steeply declining market or situation is more likely to result in financial 'cuts' than a successful recovery.
Examples
