Research signals
- SellRule RL: sell signal for 60 sessionsJan 7, 2026 · Pre-unlock risk tierPast signals (233, deals under $50M): fell 69% · median -13.9% · rallied 25%+ during the hold 49%backtest
Deal under $50M: published as a sell signal only, because shorting such shares is usually impractical (hard to borrow, high borrow fees, frequent squeezes).
- BuyRule C1: buy signal for 40 sessionsNov 25, 2025 · CapitulationPast signals (357, deals under $50M): rose 42% · median -6.8% · dropped 25%+ during the hold 49%backtest
Buy signals passed on returns relative to IPOs of the same year, size and age, most of which fall after listing. A buy signal can beat its peers and still lose money.
- SellRule F1: sell signal for 100 sessionsMar 5, 2025 · Microcap dealPast signals (387, deals under $50M): fell 73% · median -29.0% · rallied 25%+ during the hold 50%backtest
Deal under $50M: published as a sell signal only, because shorting such shares is usually impractical (hard to borrow, high borrow fees, frequent squeezes).
- SellRule R20: sell signal for 100 sessionsMar 5, 2025 · Day-20 risk tierPast signals (280, deals under $50M): fell 76% · median -33.9% · rallied 25%+ during the hold 50%backtest
Deal under $50M: published as a sell signal only, because shorting such shares is usually impractical (hard to borrow, high borrow fees, frequent squeezes).
Rules frozen as v1; signals dated from Oct 29, 2026 are live, earlier ones show what the frozen rules would have flagged. See methodology.
The rules run independently, so one IPO can carry buy and sell signals at the same time; each label reports only its own rule's history.
Past figures cover all 4,312 signals the published frozen v1 rules produce on 2014–2025 IPOs, close to close over each signal's holding period. Returns start at the close of the signal session; signals are published after that close, so the first price available to a reader is the next session's. Only 1,192 of 2,368 operating-company IPOs from those years have usable Yahoo Finance price data; most of the rest no longer trade under their IPO ticker (delisted, acquired or renamed), so the figures probably understate declines. These are hypothetical results, not trades: the rules were selected on these same years with the benefit of hindsight, so the figures likely overstate what live signals will do. The live track record is the real test. Trading costs and borrow fees are not included. Past results do not predict future results.
Research signals only, not investment advice. Lock-up terms come from prospectuses; prices from Yahoo Finance and may be delayed or wrong.
