In nineteen seventy-three, the stock market valued the Washington Post Company at about a hundred million dollars. Warren Buffett estimated that the business was worth four hundred to five hundred million. Berkshire bought shares. He believed knowledgeable analysts could have reached a similar estimate using available information. The opportunity came from comparing the offer with the business, then being willing to disagree with the price.
A share gives you partial ownership of a business. If its earning power remains intact, a falling price lets each dollar buy more of it. That helps someone who will keep buying and can afford to wait. Someone forced to sell faces a different problem. Buffett's argument depends on having both an independent appraisal and the freedom to ignore an unattractive offer. Markets often price businesses sensibly; buying whatever has fallen is no substitute for judgment.
What are you actually buying?
Buffett's estimate of intrinsic value concerns the cash owners can take out over a business's remaining life, expressed in today's money. A dollar arriving sooner is worth more than an otherwise equivalent dollar arriving later. You need to consider how much cash may arrive, when, and how confidently you can expect it. The interest available elsewhere matters too. An impressive spreadsheet cannot settle whether its forecast deserves belief.
Growth belongs inside that calculation. A company may sell more each year while spending so heavily on equipment and other necessities that little remains for owners. Growth adds value when the extra cash it produces justifies the money required. A low ratio of price to reported earnings cannot answer that question.
Even a reasonable estimate needs room for error. Buffett calls a substantial discount to a conservative valuation a margin of safety. A fall from last year's high establishes no such margin. And an excellent business can be a poor investment at an excessive price. Part of its future success may already have been paid for.
Safety concerns permanent economic loss, including what your eventual receipts can buy after tax. A deposit can repay every promised dollar while inflation consumes its purchasing power. A productive business can supply goods and services people want, generating returns without depending entirely on another buyer offering a higher price. That doesn't make every business safe. Its ability to keep producing valuable output still needs examining.
See's Candy illustrates what that examination can uncover. Its reputation came from customers' repeated good experiences with the product and staff. Those experiences gave people reasons to pay more, supporting earnings well above an ordinary return on the modest tangible assets it needed. Equipment and inventory alone could not explain those profits. Customer loyalty was doing useful economic work.
Such advantages need maintenance through better service, products, and costs. They also matter when prices generally rise. Inflation forces businesses to put more money into inventory, receivables, and eventually equipment just to preserve their earning power. A business with pricing power and modest capital needs has less to replace. It suffers less than one requiring heavy investment; inflation has not given either owner a free gain.
Buffett's textile mills faced harsher economics. New machinery promised lower costs, but competitors could buy similar machines. As they did, competition pushed selling prices down. Customers received much of the saving while producers had more money tied up in equipment. Skipping the investment risked falling behind; making it did little to improve industry returns. Even able managers could not reliably escape that problem. Over a decade, disappointing earnings can consume a discount that looked generous at purchase.
Nor does past strength guarantee future strength. Decades after the Post purchase, Buffett described newspapers losing their old advantage. Local readers had attracted advertisers, whose advertisements helped attract readers. New media gave both groups alternatives. Even the strongly placed Buffalo News faced pressure. With high fixed costs, expenses could not fall as quickly as revenue, so lost business did disproportionate damage. Prestige and civic usefulness could not restore the missing economics.
How much can you judge?
The difficult part is deciding which situation you are looking at. Buffett calls the businesses you can evaluate your circle of competence. Its boundary matters more than its size. Stable, understandable earnings are easier to estimate; a forecast whose plausible range is enormous may give no useful basis for buying. One profitable outcome doesn't establish skill, either. Luck can rescue a poor decision.
Once you own a sound business at a sensible price, watch its operations and management without trading merely because the quotation rises. Patience still allows selling when economics deteriorate, the price becomes excessive, or a better understood opportunity appears. Before buying, you can wait. When an understood bargain does arrive, failing to act has a cost too.
That approach demands knowledge. Concentrating money in a few companies makes sense only with deep understanding; Buffett favors broad, low-fee index ownership for most investors. Fees and trading costs subtract from what businesses earn, and poorly timed buying and selling can take away more. Useful services may justify their price. For the owner, the aim is to keep a reasonable share of the businesses' results, with enough judgment and financial freedom to benefit when their asking prices fall.
Three things to keep
A price decline helps buyers when durable earning power survives.
Competition and necessary reinvestment can consume an apparent bargain.
An estimate outside your competence offers little protection, however low the price.
