Top Whale Tickers in Mid-November 2026: ROKU Disposition Surge, Dollar Leaders Rotate, and Fresh Form 4 Filings

Top whale tickers in mid-November 2026 show another leaderboard rotation. As of November 13, 2026, ProBors ranks ROKU first with 210 whale-class prints in 14 days—almost entirely code D RSU dispositions from Jeff Hastings, not open-market sales. UTHR remains the busiest code S story with 163 sales in 185 prints and about $44.7 million in net reported selling, while KNSA and MSI now dominate net dollar outflow as MSGR drops off the top-thirty frequency board. Fresh multi-million-dollar sales from Hagerty (HGTY), Liberty Media (FWONK), and Carl Icahn on CTRI landed the week of November 12. This guide maps the mid-November board, a five-step triage framework when print leaders and dollar leaders diverge, recent large Form 4 rows worth a footnote read, and what leaderboard volume does not prove. This is research context, not investment advice.

Why the mid-November whale board rotated again

Whale leaderboards rank large Form 4 prints by frequency and reported value—they are not sentiment scores. Compared to the board as of November 6, 2026, three shifts stand out:

• Print-count leadership moved to Roku. ROKU shows 210 whale-class prints with about $21.0 million in net reported value. ProBors indexes 100 of those rows as code D RSU dispositions from Hastings; only 4 summary lines count as open-market sales on the 14-day board. That is a vesting-and-disposition wave, not a sudden insider exit headline.
• SUPN is still loud, but no longer alone at the top. SUPN still stacks 202 prints (merged across duplicate issuer labels) with roughly +$9.95 million net reported value—mostly non-code S activity, as in early November.
• Dollar leadership shifted away from MSGR. MSGR no longer appears in the top-thirty print ranks for this window after late-October trust distributions dominated dollar headlines. KNSA (about $69.0 million net, 53 code S sales) and MSI (about $89.2 million net, 57 sales) now carry more of the negative net-value load.

The 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 13, 2026)

The table reflects ProBors whale activity over the last 14 days as of November 13, 2026. Duplicate issuer labels for the same ticker (for example two SUPN rows) are merged by symbol. Net reported value sums directionally in the platform; sales and dispositions show as negative.

ROKU is the clearest example of why print count alone misleads: frequency exploded while open-market sales stayed rare. UTHR still rewards filtering to code S when you want exit-heavy flow—see UTHR whale insider sales explained for officer-cadence habits that persist into November.

A five-step triage framework for mid-November flow

Use the same checklist when ROKU-style dispositions compete with MSI-scale dollar selling for your attention.

1. Split print leaders from code S leaders. Sort the 14-day board, then filter Sale on tickers like ROKU, SUPN, and KVUE before inferring discretionary selling.
2. Read SEC transaction codes on every highlighted row. Grants (A), exercises (M), tax withholding (F), distributions (J), and dispositions (D) tell different stories than code P purchases and code S sales.
3. Compare net dollars to print count. MSI and KNSA can rank below ROKU on prints but ahead on net reported value—dollar rank is where estate, fund, and officer exit waves show up.
4. Measure filing lag in calendar days. A same-day November 12, 2026 filing on a same-day trade is routine; a three-day gap on an open-market purchase still deserves a footnote check.
5. Use ProBors signal scores as a queue sort, not a verdict. Scores of 5 on multi-million-dollar sales flag attention; a 0 on a small open-market buy is expected noise. Cross-check the chart and any congressional markers on the ticker workspace before sharing.

Recent filings worth a second look

The table below shows deduplicated whale rows from ProBors as of November 13, 2026. Values are as indexed in the platform; sales and dispositions appear as negative amounts.

How to read this snapshot without overfitting:

• HGTY and FWONK are fresh, same-day code S sales above nine figures combined—priority footnote reads, especially if you track media or holding-company structures.
• ROIV shows code J holder activity, not open-market selling; treat it like other distribution rows until the filing explains the transfer mechanics.
• CTRI stacks multiple Icahn sales across consecutive trade dates in the same filing window—one table row is not the full stake story.
• ASR is a rare open-market P purchase amid a sell-heavy board, filed about three calendar days after the trade date—useful for contrast, not proof of a sector-wide insider buy signal.

How to research mid-November whale flow on ProBors

1. Open the Whales tab and sort by filing date to catch November 12, 2026 batches like HGTY, FWONK, and CTRI.
2. Use the top tickers view for the 14-day window to compare ROKU print frequency against MSI and KNSA net dollars.
3. Filter by transaction type Sale when you want to hide code D and code J noise on names like ROKU and SUPN.
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 price context and any congressional markers on the same ticker.

What this does not prove

Mid-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 from summary tables alone
• That ROKU’s disposition stack means the same thing as UTHR’s sustained code S cadence
• That falling off the top-thirty list (as MSGR did this week) means insider activity ended entirely

Leaderboards are a queue, not a forecast.

FAQ

Why does ROKU rank first if most rows are not open-market sales?

Print count includes all large indexed Form 4 rows in the window. ROKU’s 210 prints are dominated by code D RSU dispositions from one reporting owner. Only four summary sales appear on the 14-day board—frequency and exit intensity measure different things.

Is United Therapeutics still the main code S story?

UTHR still shows 163 sales within 185 whale-class prints and about $44.7 million in net reported selling in this window—heavy open-market activity even as ROKU tops raw print count.

Why did MSGR disappear from the leaderboard?

MSGR trust and holder distributions inflated late-October dollar ranks. As those filings aged out of the 14-day window, other tickers like MSI and KNSA moved up on net reported value. Ticker-specific views may still show older MSGR rows.

What does signal score 5 mean on a nine-figure sale?

In ProBors, 5 marks a row worth a closer look based on size, role, and pattern—it does not prove illegal trading or predict price direction.

Where can I check ingestion health before sharing a row?

Use the public ProBors data status page, then verify any row against the original SEC filing.
