Buffett talks about investment timing: patience is important On May 3rd, Jin Shi Data reported that Buffett shared a key investment principle: patience is important, but when the best opportunity arises, quick action must be taken. He recalled receiving an unexpected phone call in 1966, asking someone to sell a company that made an annual profit of 2 million yuan at a super low price. This opportunity was fleeting, and "when a profitable and reasonable opportunity arises, there is no need to wait patiently, seize it immediately".
