Background
Dan Zanger holds the world record for the largest percentage portfolio gain in 18 months (29,233%), verified by Fortune magazine. Starting with $10,775, he turned it into over $18 million during the 1999-2000 dot-com boom using chart pattern breakouts — primarily bull flags, cups-with-handles, and ascending triangles in high-growth tech stocks.
Core Methodology
Zanger's approach is pure technical chart pattern trading: he identifies specific geometric patterns (bull flags, ascending triangles, cups-with-handles, channels) and buys the breakout when volume confirms. He combines pattern recognition with sector momentum — only trading patterns in the hottest sectors showing institutional accumulation.
Key Trading Rules
- Only trade chart patterns in leading sectors showing institutional accumulation
- Buy breakouts from bull flags, ascending triangles, and cup-with-handle patterns
- Volume on breakout day must be at least 150% of 50-day average — this is non-negotiable
- Stop loss immediately below the pattern's support line
- Let winners run: trail stop using the 10-day or 20-day moving average
- Take partial profits at measured move targets (height of pattern projected from breakout)
