How biweek works

Current version biweek 1.0

What biweek does

Every trading day, our deep-learning models scan thousands of US stocks and rank the ones with the highest modeled probability of rising +10% within 14 trading days. No human stock-picking — the models decide from data.

Two engines — pick your style

Same exit rules (trailing stop), different stock-selection models.

Steady — 8 liquid breakout names, lower drawdown
Aggressive — 10 higher-volatility small caps, bigger swings

Both engines only work as designed if you diversify across the whole list — buying just one or two picks breaks the math.

Why it can make money while missing half the calls

It's not about hit-rate — it's about asymmetry: let winners run, cut losers fast. Winners can go +10%, +40%, sometimes +100%; losers get cut near −7%. A few big winners can cover many small losses. That's the trailing-stop principle — and why diversification across all picks is mandatory, not optional.

How we validate

  • Time-series deep-learning models trained on years of US market data.
  • Walk-forward validation — tested only on future periods the models never saw, retrained per fold, three consecutive years above the S&P 500 in simulation.
  • Continuous re-validation with new data; versions increment as models improve.
  • All performance figures are simulations assuming a broker with automated stop-limit orders.

Operating rules (fully disclosed)

  • Daily ranking by modeled probability — Steady 8 / Aggressive 10, equal weight.
  • Exits: −7% hard stop / 12% trailing stop from the peak / 60-trading-day cap — whichever comes first. No fixed profit target.
  • Only exited slots are replaced by the next-ranked stock (no mid-hold switching).
Predictions, not guarantees. This is a volatile strategy — simulated max drawdowns of −21% (Steady) and −26% (Aggressive), and around −40% in bear markets. No strategy wins 100% of the time. Diversify, and only use money you can afford to risk.
