Research signals

  • BuyRule T1: buy signal for 60 sessions
    Sep 17, 2024 · Pre-unlock quality
    Past signals (642, deals of $50M and over): rose 47% · median -2.6% · dropped 25%+ during the hold 35%
    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.

  • Sell or shortRule E1: sell or short signal for 60 sessions
    Jul 30, 2024 · Weak earnings reaction
    Past signals (186, deals of $50M and over): fell 70% · median -13.6% · rallied 25%+ during the hold 33%
    backtest

    Short-selling risk: losses on a short position have no limit and can exceed the amount put up; brokers can demand more margin, recall borrowed shares or close the position; borrow fees and any dividends are owed while short and are not in the figures shown; recent IPOs are often hard to borrow and prone to squeezes.

  • BuyRule R20: buy signal for 100 sessions
    May 16, 2024 · Day-20 risk tier
    Past signals (389, deals of $50M and over): rose 46% · median -2.7% · dropped 25%+ during the hold 39%
    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.

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.
