Biography
Warren Edward Buffett was born August 30, 1930 in Omaha, Nebraska. His father was a stockbroker and congressman. By age 11 Buffett had bought his first stock (Cities Service preferred shares at $38); it fell to $27 before recovering. He vowed never to lose money again. By 13 he was filing tax returns and delivering newspapers. He was rejected by Harvard Business School — a rejection he later called the best thing that ever happened to him, because it led him to Columbia, where he studied under Benjamin Graham, the father of value investing. Graham's margin of safety principle became the foundation of Buffett's philosophy.
He returned to Omaha and ran a series of investment partnerships through the 1950s and 60s, generating returns that obliterated the market. In 1962 he began buying shares in Berkshire Hathaway, a failing Massachusetts textile mill. In 1965 he took control. Over the next six decades he transformed it from a textile company into a $900B conglomerate owning GEICO, BNSF Railway, See's Candies, Dairy Queen, Fruit of the Loom, and stakes in Apple, Coca-Cola, American Express, Bank of America, and dozens more.
His method was simple and almost impossible to replicate: buy wonderful businesses at fair prices, hold forever, don't be clever, don't be afraid during crises, don't buy things you don't understand. "The secret to success is that there is no secret." The results: $100 invested in Berkshire in 1965 was worth $3.4M in 2023. The S&P 500 returned 31,223% over the same period. Berkshire returned 4,384,748%.
Core Philosophy
Value investing and margin of safety. From Benjamin Graham, Buffett learned to buy $1 of value for $0.50 — the margin of safety. Over decades, this evolved: he moved from buying cheap bad businesses (Graham's "cigar butt" investing) to buying wonderful businesses at fair prices, guided by Charlie Munger. The difference: great businesses compound; cigar butts don't.
Circle of competence. Buffett has always refused to invest in things he doesn't understand. He missed Microsoft, Google, Amazon, and Apple in their early years. He acknowledges this freely. "Risk comes from not knowing what you are doing." His discipline around staying within what he understands has saved him from catastrophic losses that compound destroyers suffer.
Long-term orientation and temperament. Buffett's edge is not IQ — he says so repeatedly. It is temperament: the ability to be greedy when others are fearful and fearful when others are greedy. During every crisis — Black Monday 1987, dot-com 2000, financial crisis 2008, COVID 2020 — he deployed capital while others fled. "The stock market is a device for transferring money from the impatient to the patient."

Lessons for the CFO Suite
Buffett's entire philosophy begins with not losing money. Asymmetric risk management — avoiding catastrophic loss — is the foundation of long-term wealth creation.
Circle of competence discipline prevents the most expensive mistake in finance: buying what you don't understand because it's working for others.
The greatest financial advantage is not intelligence — it is the ability to remain calm when markets panic and cautious when markets euphoria. This is learnable.
Buffett's annual letters are models of financial communication. CFOs who can explain complex financial reality in plain English build more trust than those who hide behind jargon.
