The story

A critter in the spirit of Steve Cohen, who built S.A.C. Capital and later Point72, known for an intense, fast-paced trading culture. Inspired by his active, information-hungry approach to markets. Educational inspiration only.

The lesson
What a player learnsSpeed and edge in information demand equally strong risk discipline.
Strategy dossier — MomentumMomentum · medium risk

Buy what's already going up and ride the trend until it fades.

Momentum bets that recent winners keep winning and recent losers keep losing over horizons of roughly three to twelve months. A momentum investor ranks assets by trailing return, buys the strongest, and rotates out as strength decays. The edge is behavioral: investors under-react to news, then pile in late, stretching moves further than fundamentals justify. Positions are sized by relative strength rather than valuation, so price itself is the signal. Discipline lives in the exit rules, because momentum works until it violently doesn't. It is agnostic about whether a company is cheap or expensive, only whether its price is rising.

Strengths

  • Historically one of the most persistent anomalies across markets and eras
  • Simple, rules-based, and easy to backtest
  • Captures big trending moves other styles miss

Trade-offs

  • Suffers sharp 'momentum crashes' at market turning points
  • High turnover means taxes and trading costs bite
  • You are always late to the entry and late to the exit by design
