Insider Activity

Insider Activity is the Form 4 surface. Type a ticker, get the company's officer and director transactions — date, insider, buy or sell, shares, and dollar value — plus a monthly MSPR (monthly share purchase ratio) chart showing the buy-vs-sell tilt over time. Cluster buying near 52-week lows by multiple officers is a real signal; a single CEO 10b5-1 sell on schedule is not. The page surfaces the data so you can tell the difference.

What it is

A single-ticker insider-transactions feed sourced from official Form 4 filings. The MSPR chart computes monthly net sentiment from the transactions themselves: (buys − sells) / total × 100, bucketed by month. The transaction table groups rows by buy vs. sell (buy = positive change in shares, sell = negative), with each row deep-linked to the insider's Form 4 history on SEC.gov.

For market-wide insider screening (top officer buyers/sellers across all symbols today), the separate /insider-screener surface is the right entry point. This page is per-ticker only.

When to use it

When a name shows up on the scanner and you want to know who's transacting. Before any swing trade, glance at the last 90 days of insider activity — is the CFO selling into strength? Is the CEO buying on the dip? Cluster buys (three or more officers buying within a 30-day window) at the lows of a multi-year base are the highest-quality insider signal; 10b5-1 scheduled sells by executives diversifying away from a single name are background noise.

Open it

• Path: /insider (empty by default — enter a ticker); /insider?symbol=<TICKER> jumps direct and auto-runs the search
• Shortcut: none — accessible from the sidebar
• Tier-gate: free — the page itself is not tier-gated. The insider feed returns the same depth for all callers. (The Research dossier separately caps free users at the last 10 insider transactions; this dedicated page does not apply that cap)

How to use it

1. Open /insider. Type a ticker in the search box and hit SEARCH (or Enter).
2. The MSPR chart renders first — monthly bars showing the net buy-vs-sell percentage for that ticker. Positive bars (above zero) mean officers were net buying that month; negative bars mean net selling.
3. Below the chart, the transaction table lists every Form 4 on record for that ticker. The filter strip toggles ALL, BUY (rows with positive share change), or SELL (rows with negative share change).
4. Click any row to open the insider's Form 4 history on SEC.gov in a new tab — the link goes to sec.gov/cgi-bin/browse-edgar searching for that insider's name with type=4.
5. Land on the page from another surface via ?symbol=<TICKER> and the search runs automatically — used by the cross-link from Research and the scanner row context menu.

Fields

Transaction row

MSPR chart

Monthly bars: (buys − sells) / total × 100, where buys is the sum of positive-change transactions in the month and sells is the sum of negative-change transactions. Range: −100 to +100. Color: a single fill (#2962ff) regardless of sign — the bar's direction above or below zero carries the sentiment.

Limits

• Coverage depth varies by ticker. Foreign issuers and recently-IPO'd names often return shallow history (last 90 days or less)
• Transaction-type detection: rule is change > 0 → BUY, change < 0 → SELL. Option exercises that result in a net share increase classify as buys; the page does not separately tag option exercises vs. open-market purchases
• 10b5-1 plan filings are not flagged separately — a scheduled sell looks identical to a discretionary sell on the row. Cross-reference the Form 4 footnotes on SEC.gov (deep-link in the row) for the 10b5-1 indicator
• MSPR chart: monthly granularity only — no weekly or daily aggregation. Months with zero transactions render as zero (not omitted)
• No alerting on insider transactions — Form 4 filings don't trigger Tapeboard alerts; subscribe via SEC.gov RSS for that
• The SHARES column represents transaction shares (not post-transaction holdings); the dollar value field is not separately rendered — the table shows shares only
• Insider data refreshes on a several-minute cycle, so same-day Form 4 filings can take a refresh cycle to surface
• Cluster-buy detection is not surfaced as a flag — read the table

Troubleshooting

SEARCH_FOR_A_TICKER_TO_VIEW_INSIDER_ACTIVITY after searching a real ticker. The feed returned zero rows. Three causes: (1) the company has no Form 4 filers in the indexed window — common for recent IPOs and SPACs; (2) the ticker is a foreign issuer (coverage gaps); (3) typo — verify the symbol on /research/<TICKER> first.

MSPR chart is all zero bars but the table has rows. The transactions exist but their dates fall outside the months the chart computes — typically a coverage gap where shares were returned but no parsable transaction dates. Treat the table as truth; the chart is a derived view.

Row click opens SEC.gov to "No matching companies found." The insider's name has unusual characters that broke the EDGAR search URL encoding. Search EDGAR manually by name — the row gave you the spelling.

Same insider shows up 20 times in a single day. Multi-line Form 4 — one filing reports multiple transactions (e.g., an option exercise plus a same-day sale). Each line is a row. The MSPR chart sums them correctly; the table is line-level.

Page says no data but /research/<TICKER> Insider tab shows transactions. Same source — open a refresh on Research and re-run the Insider search. If the discrepancy persists, the dedicated page may be showing a stale entry; wait a few minutes and retry.
