Day Trading

Tagged in the Berkshire Hathaway Annual Letters as the foil to long-horizon ownership. The flagged passage makes the counterintuitive point that a net buyer of stocks should welcome falling prices, not rising ones — yet “emotions too often complicate the matter,” and most people (even future net buyers) “take comfort in seeing stock prices advance.” Buffett’s analogy: such shareholders “resemble a commuter who rejoices after the price of gas increases, simply because his tank contains a day’s supply.” In this corpus the tag marks the short-term, price-chasing mindset that Berkshire’s philosophy explicitly rejects in favor of buying good businesses cheap and holding them.

Context: Day trading is the practice of rapidly buying and selling securities within short windows (often the same day) to profit from small price moves — a high-frequency, speculation-driven approach generally contrasted with long-term value investing.
