❓ Why It Matters

Following crowd emotion at extremes
Mistaking confidence for certainty
Forcing trades to quickly recover losses
📚 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.
