Warren Buffett, the legendary investor, has long cautioned against two common investment pitfalls: misunderstanding one’s investment and using borrowed money to leverage it. Combining these mistakes, he warns, often leads to disastrous outcomes.
“Any time you combine ignorance and borrowed money, you can get some pretty interesting consequences,” Buffett remarked during the 1994 Berkshire Hathaway Annual Meeting. He highlighted the historical risks of excessive borrowing, noting that “the ability to borrow enormous amounts of money combined with a chance to get either very rich or very poor very quickly has historically been a recipe for trouble at some point.”
Buffett’s advice serves as a timeless reminder for investors to thoroughly understand their investments and approach leverage with extreme caution.
