True story · PetroChina, 2003

A valuation done with an annual report and a weekend

Buffett read PetroChina's annual report at home and pegged the company's value at roughly $100 billion. The market was pricing it near $37 billion. He built no spreadsheet, met no management, sought no second opinion — the gap was too wide to need precision. Berkshire bought about $488 million of the Hong Kong-listed shares.

By 2007, rising oil prices and a re-rating had carried PetroChina's market value past $250 billion. Buffett sold the entire stake for about $4 billion — roughly an eight-fold return plus dividends — and moved on.

When value is triple the price, ordinary accuracy is enough. The best decisions rarely require the most elaborate models.

True story · Warren Buffett

A fair price for a wonderful business

In 1988, just months after the Black Monday crash, Warren Buffett quietly began buying Coca-Cola shares. By 1989 Berkshire had spent roughly $1 billion — at about 15 times earnings, hardly a statistical bargain. Wall Street was puzzled: the "cigar-butt" student of Graham was paying up for a household brand.

Buffett was not valuing the next quarter. He was estimating decades of predictable owner earnings from a product sold in nearly every country on earth, protected by the strongest brand moat in consumer goods. Ten years later the stake was worth more than $13 billion, and Berkshire still holds it today — the annual dividends alone now return a large share of the original cost every single year.

A valuation model exists to estimate long-term cash generation — not to find the statistically cheapest ticker on the screen.
