📖William Gann

Price vs Value Disconnect

🌱 Beginner★★★★★

Prices diverge from value short-term but converge long-term. Ignoring valuation turns even good companies into poor investments. Overpaying compresses future returns and leaves little margin when assumptions are wrong. Estimate intrinsic value with conservative assumptions, set clear buy ranges, and act only when price offers a meaningful discount with acceptable downside. In Price vs Value Disconnect, W.D. Gann focuses on the gap between price and value. Key insight: The voting-to-weighing machine transition is inevitable. Valuation is like buying a house: the asking price reflects mood, but true value comes from structure, location, and long-term utility.

Avoid misuse: Confusing a low price with true cheapness

💬

In the short run, the market is a voting machine; in the long run, it's a weighing machine. Prices can diverge wildly from value, but eventually converge.

📚 Case Studies

1
Dot-Com Bubble Peak (2000)
The NASDAQ in early 2000 broke its prior swing lows, forming a clear downtrend per Gann’s rule of lower highs and lower lows after a parabolic rise.
✨ Outcome：Investors who sold when the trend reversed sidestepped years of heavy tech stock drawdowns.
2
Dow Jones Crash and Gann Retracements (1929)
After the 1929 peak near 381, the Dow plunged and later retraced key Gann levels, notably around the 50% and 62.5% zones, signaling potential resistance and trading opportunities for disciplined followers of percentage retracement rules.
✨ Outcome：Traders using Gann retracements managed risk, capturing partial rebounds while avoiding full re-entry before a durable long-term bottom.
