Multi-bagger strategy - paper portfolio - 2026-10-12 update

Rules: started with $1,000,000 from the picks of 2026-10-09. Every week, US stocks that have just doubled off their 52-week low (2.0-2.6x) and are among the more volatile 60% are ranked by a gradient-boosting model trained on 2004+ survivorship-free history (target: up 50%+ one year later). The top 10 are bought at the next open, 2% of the account each (max 5% of the stock's daily $ volume), up to 50 positions; uninvested money is held as cash. Companies under $500M market cap based in China, Hong Kong, Macau, Taiwan, Singapore, Malaysia, Thailand or Cayman/BVI are excluded. Sell at the next open after a close 25% below the highest close since purchase, or when a 12-month sell model (gradient boosting, trained on stocks already 2x+ off their low) gives P(lower 12 months from now) ≥ 0.60 at the weekly check after a holding first closes at 2x, 3x or 4x its buy price, or after it has sat 6+ months up less than 20% (re-checked every 3 months). Costs 0.5% per side.
