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	69% of Early-stage-graded names beat the S&P over 21 sessions (95% CI 51–82%, N=32).	Median excess vs the S&P was +3.9%.
~3 months	building — 13 more sessions needed
~6 months	building — 76 more sessions needed

How have this name's flags scored?

Flag	N	Mean excess vs S&P
Burning cash — operating margin is negative.	35	+7.4%
Thin gross margin — keeps little of each sales dollar (judge it against its industry).	20	+2.1%
Heavy dilution (~22%/yr) — top-decile share issuers have historically underperformed.	sample still too small to report (need ≥ 8)
Hyper-expansion — assets up ~118% in a year; aggressive expanders have historically lagged.	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.

From the headlines

AI take — daily, AI-generated

AI leans cautious

Absurd growth figure (118k%) is a red flag for accounting anomalies; weak margins and early-stage metrics don't justify the hype.
