📖George Soros

Review Your Investment Thesis

🌿 Intermediate★★★★☆

Regularly challenge your original investment thesis. Short-term noise often forces investors out before value is realized. Long-term discipline increases the odds that fundamentals, not emotions, drive outcomes. Extend research and review horizon, reduce unnecessary turnover, and adjust only when intrinsic value, risk, or opportunity cost materially changes. George Soros frames investing as a compounding game. Time amplifies quality and discipline, while unnecessary activity often destroys long-horizon returns. Key insight: Adapting to new facts prevents holding broken investments. Long-term investing is like planting trees.

Avoid misuse: Calling it long term while never reviewing thesis

💬

Regularly review whether your original reasons for owning a stock still hold. If the facts change, change your mind. Holding a broken thesis is the costliest mistake.
