📖Jesse Livermore

Let Profits Run

🌿 Intermediate★★★★★

Most fail by cutting winners and holding losers. A single large drawdown can erase years of progress. Risk control is not timidity; it is the operating system that keeps compounding alive. Define downside scenarios before entry, cap position size, avoid fragile leverage, and maintain liquidity so mistakes remain survivable. Jesse Livermore treats survival as the first objective. Limiting permanent capital loss, controlling leverage, and avoiding single-point failure are prerequisites for long-term compounding. Key insight: Human nature drives us to lock in small gains (certainty) and hold losses (hope). Start with a minimal checklist: Am I prepared for this game?; Do I have the required qualities?; Am I treating this seriously?.

Avoid misuse: Equating volatility with all forms of risk

💬

Cut losses short and let profits run. Most traders do the opposite and wonder why they lose.

🏠 Everyday Analogy

Risk control is like a seatbelt. It does not make the ride faster, but it keeps you alive when conditions suddenly turn against you.

📖 Core Interpretation

Jesse Livermore treats survival as the first objective. Limiting permanent capital loss, controlling leverage, and avoiding single-point failure are prerequisites for long-term compounding.
💎 Key Insight：Human nature drives us to lock in small gains (certainty) and hold losses (hope). This is backwards. Small losses are acceptable; large ones destroy accounts. Let profits run until the trend clearly reverses. Cut losses quickly when the market proves you wrong. This asymmetry—small losses, big wins—is the key to speculation.

🎙️ Master's Voice

The game of speculation is the most uniformly fascinating game in the world. But it is not a game for the stupid, the mentally lazy, the person of inferior emotional balance, or the get-rich-quick adventurer.
Livermore warned that speculation requires intelligence, work ethic, emotional stability, and patience. Those lacking these qualities should not participate. The game is fascinating but unforgiving.

Piggly Wiggly Short Squeeze (1924)
Livermore shorted Piggly Wiggly as it was cornered. Price was squeezed sharply higher, but he stuck to the trade as the corner unraveled.

2
1907 Panic Short Positions (1907)
