What is SueWallSt?

A public, reproducible scoring layer for U.S. securities-class-action–adjacent disclosure events. Free to use, open about its math, and built on data anyone can audit.

Why it exists

One number for severity

Securities-litigation triage is still a Bloomberg-and-spreadsheets workflow. Every desk reinvents the same vol-adjusted z-score against a different universe. SueWallSt is the shared denominator.

Plaintiff-side lawyers, expert economists, defense counsel, and litigation funders triage hundreds of potential securities cases per month. The status-quo workflow — manual terminal lookups, hand-keyed beta calculations, and bespoke damages spreadsheets — burns associate hours and produces results that are hard to compare across firms.

SueWallSt publishes a single 0–10 severity score (SMRS), an aggressive damages baseline (one-trader model), and a beta-matched recovery forecast for every active disclosure. Same math, same universe, same denominator — for everyone.

FAQ

Frequently asked questions

Is this legal advice?

No. Every score, damages estimate, and recovery forecast is a quantitative summary of public market data — not a litigation opinion, settlement target, or recommendation. Use it the way you would use a Bloomberg screen: as input to your own judgment.

Where do the numbers come from?

Daily OHLCV prices, sector ETFs, and the S&P 500 benchmark come from a public market-data provider. Securities-class-action filings come from a public RSS feed. The full upstream breakdown — including refresh cadence and known gaps — lives on the Data Sources page.

How often is the site updated?

New lawsuit filings are pulled hourly. SMRS scoring runs every 15 minutes against any unscored events. Damages are re-swept every 6 hours so PSLRA lookbacks stay current. Recovery cohorts refresh every 12 hours.

Why does some data look provisional?

Two structural reasons. (1) PSLRA caps per-share damages at the 90-day post-disclosure mean price; for cases filed in the last 90 days we use a rolling provisional lookback that updates on every sweep. (2) Recovery cohorts require a 60-day post-disclosure window to fit beta; events younger than that are held back from the cohort match.

Why is the SMRS for case X different from what I calculated by hand?

SMRS is a percentile-rank composite, not an absolute formula on raw inputs. Adding a single new event to the universe can shift every score very slightly because the percentile denominator changes. The four sub-scores (AR, MCL, AV, SR) are deterministic; the 0–10 scaling is universe-relative.

Can I use the data for a paper or a deck?

Yes — figures on this site are free to cite with attribution to SueWallSt and a link back to the underlying case page. The methodology is fully documented; we want the math to be auditable and the conclusions to be reproducible.

My ticker has no shares-outstanding number. Why?

Our upstream provider serves shares outstanding through a consent-gated endpoint that fails intermittently. When the field is missing we fall back to 0 and flag the score as low confidence — the SMRS is still computed, but the MCL sub-score is treated as neutral.

How do I report a bug or request a ticker?

Open an issue or email the team. We re-score on demand for any (ticker, disclosure date) pair, even outside the auto-ingested universe.
