Research signals
No rule has triggered for this IPO.
Rules frozen as v1; signals dated from Oct 29, 2026 are live, earlier ones show what the frozen rules would have flagged. See methodology.
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.
