Warren Buffett

Buffett dismantles the academic definition of risk as volatility (beta), arguing that the real risk is permanent loss of purchasing power. He explains why stock price drops should excite, not frighten, the true investor.

Buffett uses a Nebraska farm and New York real estate purchase to explain why focusing on productive assets—not daily price fluctuations—is the key to building lasting wealth. A masterclass in thinking like an owner, not a trader.

In the depths of the 2008 financial crisis, Buffett published a landmark op-ed declaring he was moving his personal portfolio entirely into American stocks. His core argument: be greedy when others are fearful, and fearful when others are greedy.
