How have Early-stage-graded names performed?
The forward returns of all Early-stage-graded names since each grade was recorded — the bucket this name currently sits in, not a forecast of this individual stock.
| Window | Forward record vs the S&P | Median |
|---|---|---|
| ~1 month | 45% of Early-stage-graded names beat the S&P over 21 sessions (95% CI 29–62%, N=31). | Median excess vs the S&P was -3.2%. |

How have this name's flags scored?
| Flag | N | Mean excess vs S&P |
|---|---|---|
| Burning cash — operating margin is negative. | 36 | -6.5% |
| Heavy dilution (~19%/yr) — top-decile share issuers have historically underperformed. | sample still too small to report (need ≥ 8) | |
| Parabolic one-day spike (+34%) in the last month — extreme single-day moves tend to mean-revert. | sample still too small to report (need ≥ 8) | |
| Volume 3.3× normal alongside the move — attention-crowded names tend to reverse over the following weeks. | sample still too small to report (need ≥ 8) | |
These per-flag figures are observational — a flag firing is not a randomized assignment, so any edge can reflect what kind of names trip a flag, not the flag itself. Descriptive, not causal.
Scope: these are forward returns vs the S&P among names still covered at each horizon's end, within the curated universe — not a survivorship-clean whole-market backtest. Names later dropped from coverage are counted as attrition (not hidden), and single-session moves beyond ±300% are treated as split/data artifacts and excluded.

AI take — daily, AI-generated
AI leans cautious
Mixed grade, no visible growth or margin data, and only 14.5 months of runway; too opaque and risky.
Generated by an AI model from the day's news — an opinion for context only. Not financial advice, not a recommendation, and not a price target.
