FOMO & The Herd
🐑 The most expensive four letters in finance are F-O-M-O. By the time something is so obviously winning that your group chat won't shut up about it, you are usually not early. You are the exit liquidity.
💡 Key idea
By the time everyone's piling into a 'sure thing,' you're usually buying the top. FOMO is how the herd buys high.
🧠 Why it matters
HERD MENTALITY is the instinct to do what everyone else is doing — once life-saving, now portfolio-threatening. When a stock or coin is mooning and everyone's getting rich, the fear of missing out overrides judgment and people pile in at the TOP. Every mania — tulips, dot-com, meme stocks, crypto runs — is the herd buying high right before the music stops.
🌍 In the real world
💡 In every bubble, the last wave of buyers is the biggest and the most confident — and they get hurt the most when it pops. 'Everyone is doing it' is a reason to be careful, not a strategy.
