Top Whale Tickers in Early November 2026: SUPN Print Surge, MSGR Dollar Flow, and Fresh Form 4 Filings

Top whale tickers in early November 2026 still skew sell-heavy, but the leaderboard stories have rotated again. As of November 6, 2026, ProBors ranks SUPN (Supernus Pharmaceuticals) with 202 whale-class prints in 14 days—the highest frequency on the board—while MSGR (MSG Rangers) carries about $238 million in net reported value, far ahead of every other ticker on dollars. UTHR and CRWD remain loud on print count, PANW stacks officer sales into a nine-figure net total, and MSM is a rare name with positive net reported value driven by grants and exercises rather than open-market buys. This guide maps the early-November board, a five-step triage framework when print leaders and dollar leaders diverge, recent large Form 4 filings worth a footnote read, and what leaderboard volume does not prove. This is research context, not investment advice.

Why the early-November whale board shifted from late October

Whale leaderboards rank large Form 4 prints by frequency and reported value—they are not sentiment scores. Three changes stand out compared to the board as of October 27, 2026:

• Print-count leadership moved to Supernus. SUPN shows 202 whale-class prints with about +$9.95 million in net reported value over 14 days. Most of that activity is non-open-market codes (holder and plan rows), not a wave of code S sales—UTHR still shows 110 code S sales in the same window.
• Micron dropped off the top-fifteen frequency list. MU dominated late-October dollar headlines through tax withholding and officer sales; it no longer appears in the top print ranks as of November 6. That does not mean Micron insider activity stopped—only that other tickers crowded the 14-day window.
• Family-holding dispositions drove the dollar rank. MSGR sits near $238 million in net reported value with 101 prints and zero open-market sales on the board summary—code J trust and holder rows explain most of the dollar stack.

The research task is unchanged: decide which tickers deserve a footnote read on SEC EDGAR, not whether the board is “bullish” or “bearish.”

14-day whale leaderboard (as of November 6, 2026)

The table below reflects ProBors whale activity over the last 14 days as of November 6, 2026. Tickers that appeared twice in the feed under slightly different issuer labels (for example SUPN) are merged here by symbol. Print counts include large Form 4 rows indexed in the platform; net reported value sums directionally (sales, dispositions, and withholding show as negative).

MSM is the clearest reminder that positive net value does not always mean open-market insider buying. ProBors indexes 5 buy-side rows on the summary, but the underlying filings in the window are dominated by grants (A), exercises (M), and withholding (F)—verify codes before you treat the name as a purchase cluster. For purchase-pattern habits, see insider buying clusters: what to look for.

Note on mixed codes: Tickers like KVUE, MSGR, and SUPN can rank on print count with low code S totals because dispositions (D), distributions (J), and plan activity also flow through whale feeds. Open the underlying filing before treating rank as a directional signal.

A five-step triage framework when prints and dollars disagree

Use the same checklist when SUPN tops frequency but MSGR tops dollars so trust distributions do not masquerade as discretionary selling.

1. Confirm the SEC transaction code

Open-market sales use code S; open-market purchases use code P. Tax withholding (F), dispositions (D), distributions (J), grants (A), and option exercises (M, X) are different economic events. ProBors shows the code and trade type on each whale row—filter here before reacting to dollar size.

2. Separate one trade date from a multi-week program

Three code S lines from the same officer on one trade date may be one decision split across tranches. PANW President Jenkins William D Jr filed multiple sales on November 4, 2026 that landed on November 5, 2026—group by trade date and filer before you count signals.

3. Measure filing lag in calendar days

Form 4 is generally due within two business days after the transaction. A 4-day lag is worth a footnote check even when the delay is not automatically a red flag. CrowdStrike CFO Podbere Burt W. shows a 2-day lag on a November 2, 2026 trade filed November 4, 2026.

4. Read signal scores as a sort key—not a verdict

ProBors signal scores weigh size, role, timing, and pattern history. A score of 10 on STX CEO MOSLEY WILLIAM D open-market sales flags sustained attention; a score of 5 on a large MSGR distribution row still deserves a footnote read when the dollar value is unusual for that filer. Sort by signal after filtering codes. For scoring details, see how ProBors trade signal scores work.

5. Cross-check chart and congressional context

Open the ticker workspace on ProBors: review price reaction since the trade date, any congressional markers, and whether the AI summary flags earnings, M&A, or lock-up events. Whale flow plus politician activity on the same name is a stronger research prompt than either feed alone—for PANW, see also PANW congressional disclosures explained.

Recent filings worth a second look

The table below shows deduplicated whale rows from ProBors as of November 6, 2026, chosen to illustrate code mix and filing lag. Values match reported amounts indexed in the platform.

How to read this snapshot without overfitting:

• KNSA combines a large same-day CEO sale with ongoing biotech exit flow across the 14-day window—one row is not the whole story.
• MSGR trust and holder code J lines can repeat similar dollar values across entities on one trade date; treat them as one distribution event until footnotes say otherwise.
• UTHR still prints heavily on code S sales even as SUPN tops raw print count with plan and holder activity.

How to research early-November whale flow on ProBors

1. Open the Whales tab and sort by filing date (newest first) to catch fresh batches like the November 5, 2026 UTHR and PANW filings.
2. Use the top tickers view for the 14-day window to compare print count (SUPN, UTHR) against net reported value (MSGR, PANW).
3. Filter by transaction type Sale when you want to hide code J and grant noise on names like SUPN and MSGR.
4. Click a row for SEC code, insider title, signal score, and a link to the original filing.
5. Jump to the Market workspace for the ticker to overlay price action and any congressional markers.
6. Add tickers with sustained officer code S cadence (CRWD, STX) to a watchlist if you want alerts on the next filing batch—not on live price.

What this does not prove

Early-November whale leaderboard volume does not prove:

• That insiders traded on material non-public information
• That a ticker will fall because officers, trusts, or holders filed large rows
• Exact post-trade holdings (reported values are as indexed, not always full position snapshots)
• That every code S row was discretionary—many reflect 10b5-1 plans, tax events, or compensation vesting paired with sales
• That a positive net name like MSM or SUPN on the summary row means coordinated open-market insider buying
• That falling off the top-fifteen list (as MU did this week) means insider activity ended

Leaderboards are a queue, not a forecast. The value is in codes, roles, timing, and pattern—not in treating every whale print as a trade signal.

FAQ

Why does SUPN rank above UTHR if UTHR has more open-market sales?

Print count includes all large indexed Form 4 rows, not just code S sales. SUPN shows 202 prints with plan and holder activity, while UTHR shows 110 code S sales within 130 prints. Frequency and open-market exit intensity measure different things.

Why does MSGR top net dollars with zero sales on the board summary?

MSGR net reported value is driven by code J holder and trust distributions in late October 2026, not open-market sales. Dollar rank can reflect estate or family-holding mechanics that read differently from officer code S cadence.

What does signal score 10 on STX CEO sales mean?

A score of 10 flags Worth watching in ProBors—it prioritizes the row in your queue based on size, role, and pattern history. It does not prove bearish intent or illegal trading.

Did Micron insider activity stop?

MU simply fell out of the top-fifteen print-count ranks for this 14-day window as of November 6, 2026. Older October withholding and officer sales may still appear on ticker-specific views even when the cross-market leaderboard rotates.

Where can I check whether ProBors ingested the latest Form 4 batch?

Use the public ProBors data status page for ingestion health, then verify any row against the original SEC filing before sharing.
