Filing of the Day
The Filing of the Day is Tapeboard's curated single-selection of the one SEC filing from the last 24 hours that most deserves your attention. Surfaced from a composite of materiality, news-co-occurrence, and market cap weighted by where the form is filed (10-K, 8-K with MA, S-1) — the one you'd want to read first if you only had ten minutes.
SEC's EDGAR publishes 5,000+ filings a day. The vast majority are noise — routine 4 sales, 13F position shifts, S-8 cover registrations. The Filing of the Day is the Tapeboard algorithm's pick of the one filing that matters most — a high-materiality 8-K with a merger break, a 10-K restatement, an S-1 with a hot company finally going public — surfaced at the top of the Filings page with a one-paragraph explanation of why it matters, written in plain English.
What it is

A single highlighted card at the top of the Filings page, distinct from the chronological list below. The card surfaces: the form type (10-K / 8-K / S-1 / 13D etc.), the issuer + ticker, the filing date, a one-paragraph trust-the-data summary of what the filing is doing (no editorial interpretation, just what the form says), and a one-tap deep-link to the full EDGAR HTML or PDF.
When to use it
- Morning routine (4-8 AM ET): one tap on Filing of the Day covers the most material overnight EDGAR news in 30 seconds. If it's a 10-K, full read takes 10 minutes (skip the 50 pages of risk factors, scan the financial statements + MD&A way the summary points you). If it's an 8-K with MA language, the summary flags the specific section to jump to.
- Mid-session: refresh the Filings page after lunch; the Filing of the Day carries forward if no higher-materiality filing has dropped in the new session.
- Cross-reference: the Filing of the Day ticker is correlated with the Squeeze Scanner — a high squeeze-score ticker with a Material 8-K is the ignition kernel. Cross-reference before consuming.

Selection algorithm
The Filing of the Day is composited from:
| Signal | Weight | Why |
|---|---|---|
| Form type materiality | 40% | 10-K > S-1 > 8-K-with-MA > 13D > 4 > 8-K (other) — a 10-K auto-beats any number of routine 8-Ks |
| News co-occurrence | 25% | The same ticker in The News Surface's headline ticker-tagged feed inside a 4-hour window — a high news count co-occur with a 10-K filing raises the rate of "this filing matters today" decision |
| Issuer market cap | 20% | Rough proxy for relevance — a $50B company's 10-K moves more portfolios than $200M micro-cap's. Buffered so a small high-materiality 8-K can beat a larger-everything-else 10-K. |
| Recency (last 24h) | 10% | A 16-hour-old filing beats a 24-hour-old once they're otherwise tied. |
| Financial media reference count | 5% | Number of times Reuters, Bloomberg, and WSJ references appear today. (News-co + this are different signals — news-co is the form-co ticker vs prior mentions; this is third-party editorial.) |
The full ranking formula is internal (it doesn't materially affect users) but the algorithm prefers form-type materiality, news co-occurrence, and large-cap concentration — in that order.
One-tap drill
Click the card. The drill renders the underlying EDGAR filing inside Tapeboard's own document viewer, with:
- The financial highlights table extracted (revenue, gross margin, opex as % of rev, net income) — a one-stop way to see "are the numbers actually broken?"
- Citation links to the most-shared news coverage of the filing
- A form-type-aware subject-hint lane (Form 4 = the specific insider transaction; 13D = the activist position-size shift; S-1 = the IPO timeline — the "when does this price discover?" question)
Cross-references
- The Filing of the Day ticker pill links directly to that ticker's Research page (
/research/:symbol) - A Squeeze Scanner cross-ref badge appears on the card if the ticker is also a top-50 squeeze candidate (an 8-K with MA language × a top squeeze setup is the textbook squeeze ignition kernel)
- The same ticker's insider-screener badge (recent insider buys within the same 5 days) appears if applicable
Pro tips
- Don't skip the 13Fs. A 13D-late 5-trillion-dollar equity shop suddenly showing 4% in a small-cap name is a signal you should never miss, but the Filing of the Day flash card often misses it — go scan the chronological list once a week for the new 13Ds.
- 8-K with "Material Definitive Agreement" language + a top squeeze ticker is the perfect storm. Form 4 code 1.01 = the company signed a big-enough contract to need an 8-K. The Squeeze scanner numbers can't tell you that.
- Use the Expert Summary — that's what it's there for. The "why this matters" paragraph is a literal paragraph, not a 200-page MD&A. Read it first; the drill button is right there if you need more.
