SEC Filing Impact Tracker
How stocks actually react to high-importance SEC filings. SEC filings only — news-wire events are not included. Every statistic is computed from Wiseek's scored filing feed (importance 7–10, U.S.-listed companies) joined to captured closing prices — free, source-linked, and downloadable. Updated several times daily.
Key findings
- Negative-sentiment filings scored 9–10 trade a median -9.44% from their publication price, and 70.8% are below it (n=589).
- Severity is monotonic: median move since publication falls from -1.02% for score-7 filings to -2.48% for score-8 and -4.94% for score-9 (n=1552/1818/1011).
- 64.7% of score-9 filings have moved at least 5% in either direction since publication — these are genuinely market-moving events, not noise.

Next-trading-day reaction, by Wiseek score (30 days)
Why are these samples small? This measure needs the closing price of the trading day after each filing, and Wiseek began capturing daily closes on July 24, 2026 — so most filings in the window do not have a measurable next-day close yet (a historical backfill is in progress and the sample grows every trading day). Currently 311 measured observations (one per ticker per trading day, after the exclusions listed in the methodology) against 5,646 raw filings in the window. A cell publishes nothing until it reaches 30 measured observations — a statistic is never computed from a handful of data points.
| Wiseek score | Median next-day move | Middle 50% range | Moved ≥5% | Measured |
|---|---|---|---|---|
| Score 7 | +0.46% | -1.30% … +2.82% | 18.7% | 139 of 1,910 filed |
| Score 8 | 0.00% | -3.13% … +2.69% | 31.3% | 128 of 2,251 filed |
| Score 9 | -0.99% | -4.45% … +2.23% | 27.9% | 43 of 1,372 filed |
| Score 10 | not enough data yet — 1 measured, needs 30 | 1 of 113 filed | ||
Share of negative score 9–10 filings that closed lower the next day: not enough data yet — 21 measured, needs 30. This fills in as daily closes accumulate.
| Group | Median next-day move | Hit rate | Measured filings |
|---|---|---|---|
| Score 9–10, negative sentiment | not enough data yet — 21 measured, needs 30 | 21 | |
| Score 9–10, positive sentiment | not enough data yet — 20 measured, needs 30 | 20 | |
| Score 7–8, negative sentiment | -0.07% | 50% | 50 |
| Score 7–8, positive sentiment | +0.95% | 58% | 162 |

Methodology
Universe: all SEC filings scored 7–10 by Wiseek's importance model for U.S.-listed tickers. Price at publication is captured when the article is published. Two reaction measures are reported. The move since publication is the change from the publication price to the ticker's most recent captured close — holding periods therefore vary within the window (0–30 days) and this measures cumulative reaction, not a fixed horizon. The T+1 result is the percentage change from the price at publication to the ticker's closing price on the next trading session after the filing's New-York calendar date. For filings published during market hours, the window includes the remainder of that session. Closing prices are the last regular-session trade from Wiseek's market-data snapshot, captured after 5:15pm ET — not the official consolidated close.
Exclusions (counted, never silently dropped): missing next-session close; price at publication under $0.10; absolute move over 300%; any stock-split taking effect inside the measurement window; sessions our capture missed. Current 30-day T+1 exclusion counts — sub_10c: 2 · calendar_gap: 5011 · missing_close: 249. For the since-publication measure, events without a captured latest close are excluded and the measured share is shown beside those tables; because delisted or halted names drop out, its negative aggregates are lower bounds.
Aggregation order: exclusions are applied first; surviving events are collapsed to one observation per ticker per NY trading day (highest score wins); statistics use the median (robust to outliers); any cell with fewer than 30 observations is reported as "not enough data yet" rather than a number. Every statistic carries its sample size.
Every underlying filing links to its Wiseek article and the primary source on SEC EDGAR. The full dataset is downloadable as CSV. You are welcome to cite these figures with attribution to Wiseek. Questions or corrections: see our editorial policy and contact page.
