Buy and Never Sell

“Buy and Never Sell” is the holding-period discipline Kyle pulls from the Berkshire Hathaway Annual Letters as an operating premise: every investment should be approached as if it were a buy-and-never-sell investment, which forces the decision to be made with the long horizon front of mind. As Kyle’s note on the letters puts it: “Every investment should be approached as if it were a Buy and Never Sell investment.” It pairs tightly with Long Term Thinking and Capital Allocation — Warren Buffett frames retaining earnings as the same decision as evaluating a new investment, so if you wouldn’t buy the business today, you shouldn’t be holding it.

In the letters themselves, Buffett and Charlie Munger state the rule plainly: “regardless of price, we have no interest at all in selling any good businesses that Berkshire owns,” and they explicitly reject “gin rummy managerial behavior” (discarding your least-promising business each turn). “Lethargy bordering on sloth remains the cornerstone of our investment style” — in one year they neither bought nor sold a share of five of their six major holdings. Buffett invokes Coca-Cola builder Robert Woodruff, who when asked when to sell Coke stock answered: “I don’t know. I’ve never sold any.” The corollary is that selling fine businesses on “scary” news is usually a bad decision. The discipline is not absolute permanence for its own sake but a refusal to churn quality holdings, anchored by durable Competitive Moats and trustworthy management.

Context: “Buy and hold forever” is closely associated with Buffett’s investment philosophy; his oft-quoted line is that “our favorite holding period is forever.” It contrasts with active-trading and momentum strategies that treat positions as short-term and disposable.
