The Greed and Fear Index (most famously, the 'Fear & Greed Index' published by CNNMoney) is a popular market sentiment indicator designed to measure the emotional state of the stock market. Think of it as a mood ring for investors. It compiles several different market indicators into a single number, typically on a scale from 0 (Extreme Fear) to 100 (Extreme Greed), to gauge whether investors are feeling bullish and piling into stocks (Greed) or bearish and selling them off (Fear). The index is built on a simple but powerful premise: excessive fear can drive stock prices well below their intrinsic value, while irrational greed can inflate them into a bubble. For adherents of value investing, this index isn't a crystal ball but a valuable thermometer for market psychology, offering clues about when to be cautious and when to look for potential bargains. It helps investors act on one of the most famous pieces of advice in finance.
The index isn't just a guess; it's a composite score calculated from seven different market indicators. Each indicator is measured on its own 0-100 scale, and the final index value is an equal-weighted average of all seven. This diversification helps to provide a more holistic view of market sentiment than any single measure could.
For a value investor, the Greed and Fear Index is a practical application of Warren Buffett's timeless advice: “Be fearful when others are greedy, and greedy only when others are fearful.” It provides a data-driven way to lean against the wind of market hysteria.
The index is best used as a tool for contrarian investing, not for precise market timing.
While useful, the Greed and Fear Index is not a magic wand. Keep these points in mind:
