How to Spot a 5% Buyback Authorization Before the Market Reacts

The information chain

Every corporate buyback authorization follows the same path:

1. Board approves the program
2. Company files an 8-K disclosing it (typically Item 8.01 "Other Events")
3. SEC EDGAR receives and posts the filing
4. Wire services and financial media pick it up
5. The story hits stock-alert apps
6. Retail investors see it in news feeds

Between step 3 and step 6 there's a window — usually 10 minutes to a few hours, sometimes days for smaller companies — where the information is technically public but not yet priced in by most participants. For small-caps with light analyst coverage, that window can matter.

The EDGAR feeds that carry the signal

SEC EDGAR publishes several real-time feeds. The relevant ones for buyback watchers:

• Full-text search RSS — search filings for keywords like "share repurchase program"
• Form 8-K feed — new 8-Ks as they arrive, filterable by ticker and item
• Company-specific RSS — per-CIK feed for any listed issuer
• Filing index — daily and hourly summary of all EDGAR receipts

These are all free. What most retail platforms do is scrape these feeds, enrich them, and re-publish on a delay. Reading them directly saves the delay.

The 8-K item numbers and keywords to filter on

Signal	Where it appears	Keyword to filter
New authorization	8-K Item 8.01 or 7.01	"repurchase program" AND "authorized"
Program expansion	8-K Item 8.01	"increase" OR "expanded" repurchase
ASR announcement	8-K Item 8.01	"accelerated share repurchase"
Tender offer	Schedule TO or 8-K Item 7.01	"tender offer" OR "Dutch auction"
Execution disclosure	10-Q Part II Item 2	"issuer purchases of equity securities"

How to spot the signal before the 8-K

The 8-K is already the fastest disclosure. But sometimes there are indicators that a buyback is coming:

• Cash flow trajectory. When a small-cap builds cash to a level that far exceeds working-capital needs, boards start asking about capital return. Watch the quarterly cash trend.
• M&A talk on earnings calls. A CEO who's been vocal about acquisitions and suddenly pivots to "we'll evaluate all capital allocation options" is often signaling a buyback.
• Analyst prompts on Q&A. If sell-side analysts start asking about buybacks on the call, management often provides a soft yes/no. A "we're evaluating" answer is often followed within a quarter.
• Post-drop 8-K frequency. Companies that have taken a large price drop are more likely to authorize a buyback within 30-90 days.

The filter to make it useful

Not every 8-K "repurchase program" is a real signal. Filters that separate signal from noise:

• Size floor: authorization at least 3% of market cap. Below that, it's likely SBC offset.
• Market cap filter: $50M-$2B — where buybacks actually shrink float.
• Prior execution filter: company has executed at least one prior buyback authorization to some degree.
• Insider filter: no simultaneous Section 16 insider selling.

Applied together, these filters reduce the daily "buyback announcement" firehose to a much smaller list of real signals — often just a few names a week.

Why this workflow beats the news feed

• You see the actual filing, not a summary
• You see it at the SEC's timestamp, not the wire's
• You control the filters — mega-cap noise is out
• You can cross-reference with insider Form 4 filings in the same window
