RESEARCH — THE FILING TAPE #128

Twelve of 147: Oakmark Holds 55.6% of the Tracked Equifax Stake, and the Verified Cohort Fell 4.2% in a Quarter When the Price Fell 11.9%

October 19, 2026

GetCoattail Research — The Filing Tape #128. Equifax surfaced on a trending-stocks screen this week listed as a Moderate Buy with one Buy rating and two Holds, and the filings describe a register leaning the other way: 12 of the 147 superinvestors held the stock at June 30, 2026, totalling 13,398,441 shares, and the nine holders both register methods could pair against the first quarter fell a combined 4.2% while the price fell 11.9%. Insiders have bought exactly once in the parsed record, Congress shows a single sale and no purchase, and short interest more than doubled in a year to within 0.6% of its series record.

The Hype

Equifax's attention this week is a screen story. The stock appeared on TipRanks' Trending Stocks by Analyst screener — SMTC, SCHW and JBHT topped the page's order, followed by covered, skipped or just-published names including BNY, USB, CRWV, META and TRU — listed as a Moderate Buy with a price target of $201.33 (24.86% upside as printed), 1 Buy, 2 Hold and 0 Sell ratings, a printed one-month change of -1.56%, a market value of $18.94B as printed, in Industrials, with its last rating dated October 16, 2026. TipRanks Our price file shows the path behind the screen: the stock fell 11.9% in the second quarter, from $180.07 on March 31 to $158.72 on June 30, then fell again to $140.00 by October 2 — down 11.8% from the June 30 close, down 35.5% year to date, and 41.6% below the 252-session high of $239.68 (October 8, 2025).

The Tape

For Equifax — the one hundred and twenty-eighth Filing Tape audit — the tape shows twelve June holders whose verified core shrank 4.2% in a falling quarter, a full market shedding filers while adding shares, an insider record with one purchase against 63 sales, a Congress row that records a single sale and nothing else, an all-passive 5% register whose two largest recent prints point down, and a borrow that more than doubled in a year.

Lens 1 — the superinvestors: twelve June holders, one at 55.6% of the stake, a verified cohort down 4.2%. We track 149 managers whose 13F portfolios we collect from SEC EDGAR — 147 are in the collection (144 at a June 30 period-end, 3 early filers at September 30, none of them holding this name, so there is no period split) — and the June 30, 2026 register for the common stock (CUSIP 294429105) is 12 distinct managers holding 13,398,441 shares worth $2,126,605,872, long only, with no option rows and no debt rows: 5 are labelled DECREASED, 3 INCREASED, 2 NEW and 2 UNCHANGED, with one exit. Bill Nygren - Oakmark Funds is the largest: 7,447,263 shares worth $1,182,029,617 — 55.6% of the tracked stake — at a 1.57% portfolio weight, labelled DECREASED at -1.1% (filed August 14, 2026). The second holder, Generation Investment Management, holds 1,832,583 shares (13.7%, INCREASED +3.2%, at a 2.83% weight), so the top two hold 69.3% — 9,279,846 shares — between them. The remaining holders are Darsana Capital Partners (1,500,000 shares, UNCHANGED 0.0%, at a 1.07% weight), John Armitage - Egerton Capital (1,481,188 shares, NEW, at a 2.27% weight), Jensen Investment Management (370,551 shares, DECREASED -52.7%, at a 1.43% weight), Harding Loevner (252,498 shares, DECREASED -22.3%, at a 0.38% weight), Wallace Weitz - Weitz Investment Management (191,980 shares, INCREASED +2.3%, at a 2.11% weight), AKO Capital (134,439 shares, DECREASED -66.7%, at a 0.50% weight), Vulcan Value Partners (90,748 shares, NEW, at a 0.44% weight), Thomas Gayner - Markel Group (72,850 shares, UNCHANGED 0.0%, at a 0.09% weight), Hillman Capital Management (12,541 shares, DECREASED -7.5%, at a 1.44% weight) and Lindsell Train (11,800 shares, INCREASED +2.6%, at a 0.07% weight). The change verifies row by row for nine of the ten continuing holders under two register methods that agree exactly (methodology): those nine held 12,198,344 shares at March 31 and 11,692,066 at June 30 (-506,278 shares, -4.2%), with Jensen alone cutting 412,549 shares. The tenth continuing holder, AKO Capital, could not be paired by either method, but the pipeline register carries its rows directly — 403,774 shares at March 31 and 134,439 at June 30, exactly reproducing its -66.7% label. The full register reconciles with no residual: 14,393,497 shares at March 31 (the verified 12,198,344, plus AKO's 403,774, plus the 1,791,379 shares of William Von Mueffling - Cantillon Capital Management, the quarter's one exit) moving to 13,398,441 at June 30, a register change of -6.9% that differs from the verified cohort's -4.2% because the register also counts the two new holders, the exit and AKO's cut. Eleven rows imply $158.72 and one, Harding Loevner's, implies $158.74; the cohort implied price is $158.72, the June 30 close. 13F figures are as of June 30, 2026, published up to 45 days later.

Equifax through six filing lenses
Chart 1: Signal presence by cohort (n = 12 superinvestor holders among 147 managers, at Jun 30, 2026, long only; no option rows; no September 30, 2026 early filer holds this name). Superinvestors: 2026Q2 13F collection, as of Jun 30, 2026. Institutions: full-market 13F aggregation, Jun 30, 2026 (n = 835 filers). Insiders: Form 4 through Oct 2, 2026 (n = 100 filings). Congress: PTR aggregates through Oct 3, 2026 (Senate through Oct 1, 2026) — one recorded sale in the combined and House aggregates, no Senate row. 13D/G: parsed filings through May 14, 2026 (n = 11 filings). Short interest: FINRA settlements through Sep 15, 2026 (n = 137 settlements, symbol EFX only). Source: SEC EDGAR; FINRA; GetCoattail collections.

Lens 2 — institutions: 25 fewer filers reporting 12.7% more shares. At June 30, 2026, 835 institutions reported positions, down 25 from 860 at March 31 (-2.91%); 831 are long. Reported shares rose 12.7%, from 105,476,299 to 118,869,518 (+13,393,219 shares), and reported value rose 4.43% to $18,309,922,813, labelled "reported" because the aggregate includes option rows (methodology). Flow counts agree: 750 entered, 775 exited, net -25, and the by-CUSIP row matches the by-ticker row on every field. The reported value implies $154.03 against a June 30 close of $158.72 (-2.95%).

Lens 3 — insiders: one purchase in the entire parsed record, against 63 sales. The parsed Form 4 record holds 100 filings through October 2, 2026, and it contains exactly one purchase transaction: 2,400 shares for $464,928 by one officer buyer, inside the one-year window; the 90-day window holds no purchase at all. Sales run the other way, and every one of them is an officer sale. The last 90 days hold 9 sales: 42,291 shares for $7,352,074.58, by 2 sellers, across 5 filings. The one-year window holds 46 sales (195,013 shares, $38,459,419.26, 4 sellers), and the full record holds 63 sales (315,561 shares, $68,349,076.23, 5 sellers). The sales imply $173.84 per share over 90 days, $197.21 over one year and $216.60 over the full record, each inside its window's close range on our price file, and the single purchase implies $193.72, inside its window's range — so the dollar totals are cited for all three windows.

Lens 4 — Congress: a row, and inside it a single sale. The combined record (as of October 3, 2026) and the House aggregate (as of October 3, 2026) each carry a row for this name, and the row records 1 sale transaction, 0 purchases, and no member attribution — the aggregates print a member count of zero and an empty party list, so no member can be named from them. The Senate aggregate (as of October 1, 2026) carries no row. That is the whole of this lens: one recorded sale, no recorded purchase, no name attached.

Lens 5 — the 5% register: 11 filings, every one of them passive, maximum 12.34%. Our full parse holds 11 SC 13D/G filings matching the site aggregate — 0 SC 13D family and 11 SC 13G family (3 SC 13G, 8 SC 13G/A); 8 amendments, 7 reporter names across 12 reporter rows. The maximum is 12.34%: The Vanguard Group printed 15,282,951 shares at 12.34% as of September 30, 2025 (filed October 30, 2025, SC 13G/A) — and the same name later printed 0 shares at 0.0% as of March 13, 2026 (filed March 26, 2026, SC 13G/A), while Vanguard Capital Management separately printed 9,020,869 shares at 7.47% as of March 31, 2026. Capital International Investors printed four times on a path that ends lower: 9,093,568 shares at 7.3% as of December 31, 2024, rising to 10,682,406 shares at 8.6% as of June 30, 2025, then falling through 6,591,029 shares at 5.4% as of December 31, 2025 to 3,820,844 shares at 3.2% as of March 31, 2026 — the register's latest filing, filed May 14, 2026. T. Rowe Price Associates printed 7,046,601 shares at 5.6% as of March 31, 2025 and 5,895,460 shares at 4.7% as of June 30, 2025. Harris Associates printed 7,557,127 shares at 6.2% as of December 31, 2025, on two affiliated reporter rows for one position. BlackRock printed 8,547,536 shares at 6.9% as of December 31, 2024.

Lens 6 — short interest: a record set in August, more than double a year ago. The latest FINRA settlement, September 15, 2026, records 7,748,296 shares sold short — 6.60% of the 117,484,896 shares outstanding — at 5.64 days to cover, down 0.63% from the prior settlement. That prior settlement, August 31, 2026, is itself the story: 7,797,437 shares, the maximum across all 137 settlements in the series, which begins January 15, 2021; the latest reading sits 0.6% below it. The series minimum is 1,548,501 on November 30, 2021. Against June 30, 2026 (6,521,422) the latest is up 18.8%, and against a year ago (3,380,925 on September 15, 2025) up 129.2%. The recent path runs 6,521,422 (June 30), 6,626,153 (July 15), 6,973,116 (July 31), 6,407,622 (August 14), 7,797,437 (August 31) and 7,748,296 (September 15) — three rises and one fall before the small step back. The series is published as collected.

Chart 2: Shares sold short in Equifax at each FINRA biweekly settlement, Jan 15, 2021 – Sep 15, 2026 (n = 137 settlements, symbol EFX only; the issuer-name field appears in a single spelling, "Equifax, Incorporated"). The series maximum, 7,797,437 shares, was set on Aug 31, 2026; the latest reading, 7,748,296 shares on Sep 15, 2026, sits 0.6% below it, 18.8% above the Jun 30, 2026 settlement of 6,521,422 and 129.2% above the year-ago settlement of 3,380,925. No single-step ratio in the series reaches 2 times — the largest step is 1.477x — and no step falls to 0.5 times or below; the series is plotted as collected, with no smoothing.

The Gap

The narrative arriving this week is an analyst-consensus story: a Moderate Buy trending listing, one Buy rating against two Holds and no Sell, a printed target above the last close, on a stock down 35.5% year to date. The June tape does not back it. The tracked cohort's verified core shrank 4.2% in the quarter — five of its twelve holders cut, including a 52.7% cut and a 66.7% cut — and the register as a whole shrank 6.9% even as two new holders arrived. The full market added 12.7% more shares through 25 fewer filers, so the buying the aggregate shows is concentration, not breadth. Inside the company, the record holds one purchase ever against 63 sales. The 5% register's two clearest recent paths — Capital International from 8.6% to 3.2%, and the Vanguard Group name from 12.34% to a 0.0% print — point down. And the borrow more than doubled in a year to a series record in August. One plausible reading is that the filings describe distribution into a falling stock: the screen says Moderate Buy, while every lens that records a direction in this audit records more selling, trimming or borrowing than buying.

Six of the 83 superinvestors we track hold Tesla — one name is 84.8% of the cohort — and the cohort cut its aggregate share count 33.2% in the second quarter while all institutions added 27.9%, insiders filed one report in 90 days with zero purchases in a year, and short interest sits at 1.74% of shares outstanding.
80% Overlap, No Copycat Signal: Congress vs. the Superinvestors
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.
