📖Stanley Druckenmiller
Price Confirmation
Wait for price confirmation before increasing position size aggressively.
Wait for price to confirm your thesis before sizing up. The market provides feedback.
🏠 Everyday Analogy
📖 Core Interpretation
In Price Confirmation, Stanley Druckenmiller focuses on the gap between price and value. Returns come from paying less than what a business is worth, not from guessing short-term market moves.
💎 Key Insight：Druckenmiller starts positions small and adds aggressively only after the market confirms his thesis through price action. This approach limits losses when wrong while maximizing gains when right. Many investors make the mistake of sizing positions fully at entry, leaving no room to add as conviction increases. Starting small allows you to see if your thesis is correct before committing serious capital. When price moves in your favor, add to the position. When it moves against you, exit quickly. This dynamic sizing based on confirmation is a core principle.

❓ Why It Matters
Ignoring valuation turns even good companies into poor investments. Overpaying compresses future returns and leaves little margin when assumptions are wrong.
🎯 How to Practice
Estimate intrinsic value with conservative assumptions, set clear buy ranges, and act only when price offers a meaningful discount with acceptable downside.
🎙️ Master's Voice
Never invest in the present. The present is already in the price.
Druckenmiller always looks forward. Current conditions are priced; future changes create opportunities.
