RESEARCH — THE FILING TAPE #173

Sixteen of 147: The Superinvestors' Verified Cohort Cut Analog Devices 29.5% While the Full Market Added 17.5% — and Its Insiders Have Never Bought a Share.

October 24, 2026

GetCoattail Research — The Filing Tape #173. Analog Devices (ADI) is one of the most-searched stocks on Zacks.com as of October 23, 2026 — up 0.8% over the past month against a −1.2% S&P 500, per the Zacks note. The filings show 16 of 147 tracked funds holding 6,341,679 shares of Analog Devices common stock, $2.52 billion reported, as of June 30, 2026: the verified continuing cohort cut 29.5% in Q2 while the full 13F market added 17.54% more shares; insiders recorded zero open-market buys in our 141-filing parsed record; three members of Congress disclosed small trades; the passive 13G register's largest current holder is Vanguard Capital Management at 7.47% after The Vanguard Group dropped below 5%; and short interest is down 28.3% from the June settlement, at 1.78% of shares outstanding.

① The Hype

Analog Devices is not a story stock in the way this series usually means it. It is a $200-billion analog semiconductor maker — the kind of name that trends when the market is working through a tech sell-off rather than chasing one. On October 23, 2026, Zacks.com noted that ADI "has been one of the most searched-for stocks on Zacks.com lately," alongside a modest past-month return of +0.8% against a −1.2% S&P 500 composite, while its industry bucket (Zacks Semiconductor — Analog and Mixed) lost 5.5%.

The price context around that note is a stock that ran hard and then cooled. Our price file ends October 2, 2026, with ADI at $417.15 — up 23.9% in Q2 (from $320.58), up 52.4% year to date, up 72.6% from a year earlier. The daily-refreshed close is fresher than our file: $385.76 on October 22, 2026 — 13.5% below the 52-week high of $445.91. So the search spike sits on a pullback, not a breakout.

Our file cannot verify the Zacks note's price figures themselves — they are external, stated as such, and the link is above. What the files can do is check whether the searchers' interest is matched by the filings.

Superinvestors. Sixteen of 147 tracked funds held ADI common stock at June 30, 2026: 6,341,679 shares, $2.52 billion reported — 1.447% of all 13F-reported ADI shares. The direction is the story: 11 of the 16 cut, 3 added, 2 are new. The verified continuing cohort (14 funds, paired by unique CUSIP-overlap accession matches) fell 29.5% in Q2 — from 8,994,218 shares to 6,338,363, a reduction of 2,655,855 shares. A stricter pairing method (13 funds, requiring the label recompute to match) gives −28.2%: same direction, same magnitude. The cuts ran deep: Cantillon Capital Management −95.4% (1,911,491 to 88,014), D1 Capital Partners −65.1% (292,444 to 102,040), Giverny Capital −45.4% (171,052 to 93,310), AKO Capital −40.1% (1,029,523 to 616,881). The increases were smaller: Atalanta Sosnoff +10.4%, Winslow Capital +10.2%, PineStone Asset Management +7.2%. First Pacific Advisors remains the largest tracked holder at 1,598,506 shares (25.2% of the cohort) — but even it cut 7.2%. The two new lines are token: Maverick Capital 2,704 shares, Brave Warrior Advisors 612 shares. First Eagle exited its 48 shares. The cohort's implied price of $397.17 lands exactly on the June 30 close — clean arithmetic, a shrunken register.

Verified tracked cohort in ADI
Chart 2: Verified share change per tracked manager, Q1 to Q2 2026 (n = 14 continuing holders paired by unique accession matches, cohort −29.5%; n = 2 genuine new holders; 1 trivial exit of 48 shares; register reconciles to zero residual both quarters). 13F figures are as of Jun 30, 2026; funds have up to 45 days after quarter-end to file. Source: SEC EDGAR; GetCoattail collection (adi_lens_data.csv).

All institutions. The broad 13F market moved the other way. Filers grew to 2,289 (+189, +9.0%), reported shares grew 17.54% to 438,163,853 — a net add of 65.4 million shares — and reported value rose 50.82% to $170.27 billion (value includes option rows, so shares are the cleaner signal). The single-CUSIP fixture check matches exactly. While the tracked cohort's verified continuing line fell 29.5%, the full market's register added 17.5% more shares — a clean divergence between the smart-money cohort and the institutional average.

Insiders. The parsed record is a one-way ledger: 141 filings from January 3, 2025 to September 23, 2026, zero open-market buys, 278 sells totaling 477,064.79 shares and $141.63 million from 10 distinct sellers. Over the last year, 201 sells of 289,797.79 shares ($99.39 million) from 9 sellers. In the last 90 days: 18 filings, 59 sells of 46,179 shares ($17.16 million) from 4 sellers, with 6 officer sells and zero officer buys. Implied sale prices pass their price gates in every window (w90 $371.53, w1y $342.97, full-record $296.87 — each inside the price file's range for the same window). Our site's insider aggregate shows the same direction (zero buys) but counts fewer 90-day sells (36 vs our 59; $11.79M vs $17.16M) — an aggregation-method difference, stated here so both numbers are on the record.

Congress. Small prints, both sides of the tape. The combined aggregate (through October 3, 2026) records 1 buy and 5 sells. The member file names three: Rep. Josh Gottheimer (D) bought once, in the $1,001–$15,000 band, on May 19, 2026; Rep. Thomas Kean (R) sold twice through June 30; Rep. Richard McCormick (R) sold twice through July 30. The single Senate sell is unattributed in the members file — an attribution gap in our data, though the totals reconcile. Every disclosed amount sits in the lowest reporting band.

13D / 13G. Seven filings, three reporters, four amendments — all passive. The register maximum is The Vanguard Group's SC 13G/A at 10.0% (49,618,676 shares, filed March 6, 2026, as of February 28, 2025). Then the interesting row: Vanguard Group filed another SC 13G/A on March 26, 2026 — at 0.0 shares, 0.0% — dropping below the 5% reporting threshold. The largest current print is Vanguard Capital Management's SC 13G at 7.47% (36,512,048 shares, filed April 29, 2026, as of March 31, 2026). JPMorgan Chase cycles between 4.3% and 5.0% passive across four filings. The aggregate matches the parsed filings exactly. There is no activist (13D-family) row in the register.

Short interest. Shorts covered steadily into September. From the June 30, 2026 settlement (12,030,161 shares), the series fell to 8,621,427 shares at September 15 — −28.3%, with 2.67 days to cover and 1.78% of shares outstanding. That is +3.2% versus a year ago (8,350,588), and the 2021 peak of 42.4 million shares is 79.7% above the current print — the bears have been leaving for years, and kept leaving through Q3.

③ The Gap

The search story and the filing story disagree on where the conviction sits. Zacks' searchers are arriving after a stock ran 23.9% in Q2 and then faded 13.5% off its high. The filings show the tracked money fading with it — the verified cohort cut 29.5% in the same quarter the price was rising. One plausible reading is that the Q2 rally ran ahead of the filings: the cohort took the strength as an exit window while the broad register kept accumulating. But the record shows positions and quarter-ends, not intent or intra-quarter timing — so that reading stays marked as a reading.

The second half of the gap is sharper. Across the same climb that took the stock 72.6% higher year over year, insiders sold: 278 sells, 477,064.79 shares, $141.63 million across our parsed record, with zero open-market buys in 141 filings. Not a single officer purchase. The congressional record adds one small buy and five small sells — all in the lowest reporting band, closer to noise than signal. The 13G register's most telling row is the one at zero: Vanguard Group's drop below 5%, reported on March 26, 2026, leaving Vanguard Capital Management's 7.47% as the largest current passive print.

If anyone was selling into the Q2 strength, the filings name the four managers that cut hardest: Cantillon's 95.4% cut alone removed 1,823,477 shares, D1's 65.1% cut another 190,404, Giverny's 45.4% another 77,742, AKO's 40.1% another 412,642. That is the cut side. The add side — the full market's +17.54% shares and +9.0% filers — sits outside the tracked 147, in the institutional average. The tape does not say who is right; it says the smart-money cohort and the full market moved in opposite directions in Q2, while insiders never bought and shorts kept covering.

④ What Would Change the Picture

Nothing above is a recommendation. It is a record. The next filing cycles will rewrite that record one row at a time — here is what would change the picture, all checkable in future filings:

Four of five congressional stock buys land in a stock the superinvestors hold — 688 shared names. But ticker by ticker, how often Congress buys a stock has almost nothing to do with how many managers hold it (ρ = 0.099), and the shared names did not pay better.
