Seven of 147: Bill Nygren - Oakmark Funds Is 68.3% of the Superinvestors' State Street Stake. Its Insiders Have Bought Once.

GetCoattail Research — The Filing Tape #116. State Street surfaced on a trending-stocks screen this week listed as a Moderate Buy, after a quarter in which its price rose 34.0% — and the filings describe a small, shrinking tracked register: 7 of the 147 superinvestors hold the stock, the top holder at 68.3% of the stake, verified continuing holders down 45.2%, insiders with exactly one purchase in the full record of 138 filings — 2,500 shares, and never an officer — and short interest at 1.91% of shares outstanding.

The Hype

State Street's attention this week is a screen story. The stock appeared on TipRanks' Trending Stocks by Analyst screener — in crawl order BAC, BLK, SCHW, WDAY, UNH, META, SMTC, JBHT, C and RKLB, all already covered in this series, came first, and State Street followed, listed as Moderate Buy trending in a snippet dated October 16, 2026. TipRanks Our price file describes why a screen would catch it: the stock rose 34.0% in the second quarter, from $126.56 on March 31 to $169.60 on June 30, then added 3.8% to close at $175.96 on October 2 — up 36.4% year to date, 9.4% below the 252-session closing high of $194.26 (September 4, 2026) and 58.5% above the 252-session low of $111.00 (October 10, 2025). That is exactly the setup this series exists to check against the filings.

The Tape

For State Street — the one hundred and sixteenth Filing Tape audit — the tape shows a seven-holder cohort whose continuing members verified down 45.2% in a quarter when the price rose 34.0%, a full market adding filers and shares, an insider record with exactly one purchase against 38 sales, a congressional row of one sale and no purchases, five passive 5% filings headed by a 13.04% print, and a borrow at 1.91% of shares outstanding, 19.9% below its 2021 peak.

Lens 1 — the superinvestors: seven holders, the top one 68.3% of the stake, and the continuing five verified down 45.2%. 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 holding this name) — so all seven holders sit on the June 30, 2026 period-end, on the single CUSIP 857477103, totalling 6,979,936 shares worth $1,183,799,812, long only, with no option rows at all. Bill Nygren - Oakmark Funds is 68.3% of that stake: 4,765,306 shares worth $808,195,891 — at a 1.07% portfolio weight, decreased 22.5%. GQG Partners holds 1,106,046 shares worth $187,588,074 — 15.8% of the stake — labelled NEW at a 0.35% weight; the top two together are 84.1%. Yacktman Asset Management holds 919,740 shares worth $155,987,904 — 13.2% — at a 1.93% weight, increased 1.2%. Then Christopher Davis - Davis Advisors at 147,966 shares worth $25,095,034 — 2.1% — decreased 2.8% at a 0.11% weight; Dodge & Cox Funds at 33,325 shares worth $5,651,920 — 0.5% — decreased 99.0%; Guinness Asset Management at 6,322 shares worth $1,072,211 — 0.1% — decreased 30.6% at a 0.02% weight; and Richard Pzena - Pzena Investment Management at 1,231 shares worth $208,778 — 0.0% — labelled NEW. Both NEW labels are genuine: neither name has a first-quarter register row under its filing prefix. The five continuing holders verify row by row against the first quarter, moving from 10,718,321 shares at March 31 to 5,872,659 at June 30 (-4,845,662 shares, -45.2%) — Oakmark from 6,147,935 to 4,765,306, Davis from 152,200 to 147,966, Dodge & Cox Funds from 3,499,879 to 33,325, Yacktman from 909,191 to 919,740 and Guinness from 9,116 to 6,322; no tracked manager exited — the Dodge & Cox position, cut 99.0%, still holds 33,325 shares. Every row implies exactly $169.60, the June 30 close. 13F figures are as of June 30, 2026, published up to 45 days later.

Lens 2 — institutions: 140 more filers, 14.96% more shares, and a reported value up 51.51%. At June 30, 2026, 1,257 institutions reported positions, up 140 from 1,117 at March 31 (+12.53%); 1,252 are long. Reported shares rose 14.96%, from 217,573,709 to 250,132,983 (+32,559,274 shares), while reported value rose 51.51% to $40,900,751,503, from $26,996,283,865, labelled "reported" because the aggregate includes option rows (see methodology). Flow counts agree: 1,089 entered, 949 exited, a net of +140. The name carries a single CUSIP in this aggregation, and the by-CUSIP row matches the by-ticker row on every field. The reported value implies $163.52 per share against a June 30 close of $169.60, a gap of -3.59% — below the close, printed as found.

Lens 3 — insiders: exactly one purchase in the full record, none by an officer, against 38 sales. The parsed Form 4 record holds 138 filings through October 2, 2026, and it contains exactly one purchase transaction: 2,500 shares for $312,475.00, by 1 buyer, in the last year — and no officer purchase in any window. The last 90 days hold 0 purchases and 4 sales: 30,334 shares for $5,588,538.08, by 4 sellers, all 4 of them officer sale transactions, across 9 filings. The one-year window holds the single purchase and 18 sales: 143,534 shares for $21,098,012.36, by 8 sellers, 18 of them officer sales, across 68 filings. Across the full record: 38 sales totalling 323,204 shares for $39,280,669.10, by 12 sellers, 34 of them officer sales. Every window prices inside its range — the purchase implies $124.99, 90-day sales imply $184.23, one-year sales $146.99 and full-record sales $121.54 — so dollar totals are cited for every window.

Lens 4 — Congress: a row of one sale and no purchases, and no Senate row. The combined record (as of October 3, 2026) carries a row for this name recording 0 purchase transactions and 1 sale transaction, with no member listed in the row, no last-purchase date and no party recorded. The House aggregate (as of October 3, 2026) carries the identical row, and the Senate aggregate (as of October 1, 2026) carries no row — so the recorded congressional activity in our archives is one sale sitting in the House file, and nothing else.

Lens 5 — the 5% register: five filings, all passive, headed by The Vanguard Group. Our full parse holds 5 SC 13D/G filings matching the site aggregate — 3 SC 13G and 2 SC 13G/A, 2 amendments, 5 reporter names in 6 reporter rows, no 13D at all. The register maximum is The Vanguard Group at 37,212,748 shares (13.04%) as of June 30, 2025 (filed July 29, 2025, SC 13G/A), and the latest filing prints a pair: FMR LLC at 13,854,212.89 shares (5.0%) and Abigail P. Johnson at the same 13,854,212.89 shares (5.0%) as of June 30, 2026 (filed August 6, 2026, SC 13G). The remaining filings are Vanguard Capital Management at 20,493,476 shares (7.35%) as of March 31, 2026, Vanguard Portfolio Management at 16,181,474 shares (5.8%) as of March 31, 2026, and The Vanguard Group at 0 shares (0.0%) as of March 13, 2026, recorded as filed. The 101,596,123.78-share total counts reporter rows across dates, not distinct stakes — the FMR pair alone prints the same shares twice.

Lens 6 — short interest: 1.91% of the share count, 19.9% below its 2021 peak, with no flagged step in the series. The latest FINRA settlement, September 15, 2026, records 5,247,276 shares sold short — 1.91% of the 274,701,765 shares outstanding — at 3.51 days to cover, up 12.33% from the prior settlement (4,671,416 on August 31, 2026). The series maximum across 137 settlements is 6,554,892 on March 31, 2021, so the latest sits 19.9% below that peak; against the June 30, 2026 reading of 5,016,917 it is up 4.6%. The recent path runs 5,016,917 (June 30), 5,064,704 (July 15), 4,853,653 (July 31), 4,648,897 (August 14), 4,671,416 (August 31) and 5,247,276 (September 15). No single-settlement step reaches 2 times: the largest is 1.59 times on March 31, 2022.

The Gap

The narrative arriving this week is a quality-and-momentum story: a Moderate Buy trending listing on a custodian bank that rose 34.0% in the second quarter. The filings describe tracked money reducing into that strength while the broad market added. The five continuing tracked holders cut a verified 45.2% in the quarter — including a 99.0% cut at Dodge & Cox Funds, which kept only 33,325 shares — while the two new tracked holders added 1,107,277 shares between them, insiders bought exactly once across 138 filings and never through an officer, and the congressional row holds one sale and no purchases. The broad market moved the other way: 140 more filers and 14.96% more shares. The borrow, at 1.91% of shares outstanding, is small and sits 19.9% below a peak set in 2021. One plausible reading is that the trending case rests on the price path and the broad register, while the June tape for the tracked cohort specifically shows a register getting smaller at the top — Oakmark at 68.3% after cutting 22.5% — not larger.

What Would Change the Picture

Nothing above is a recommendation. These filings would change it:

• 1. The 2026Q3 13F season (filing window closing mid-November 2026). All seven holders sit on a June 30 period-end. Whether Oakmark's 4,765,306-share position — 68.3% of the cohort, after a verified 22.5% cut — and Dodge & Cox Funds' remaining 33,325 shares are still there decides whether this lens reads as trimming or as an exit in progress.
• 2. A second insider purchase, or a first officer purchase. The record holds exactly 1 purchase — 2,500 shares — in 138 filings, and 0 officer purchases. A second purchase would break the one-purchase record; an officer purchase would be the first of its kind here.
• 3. A first congressional purchase. The combined and House aggregates record 1 sale and no purchases, and the Senate archive holds no row. A first recorded purchase in either chamber would open this lens.
• 4. A fresh 5% print above 13.04%, or a first 13D. The register's maximum is The Vanguard Group print of 13.04% as of June 30, 2025; its newest filing is the FMR pair at 5.0% as of June 30, 2026. A new filing moving the maximum, or a first 13D, would change this lens.
• 5. Short interest back through the March 2021 peak. The borrow stands at 5,247,276 shares, up 12.33% on the settlement and 19.9% below the March 31, 2021 peak of 6,554,892. A reading at or above 6,554,892 would set a new series high.

Methodology and data notes

• As-of & limits: The lenses rest on different clocks, none live: 13F is a June 30, 2026 snapshot published up to 45 days later; Form 4 runs through October 2, 2026; Congress aggregates run through October 3, 2026 (Senate through October 1, 2026); 13D/G through August 6, 2026; short interest through September 15, 2026; the price file ends October 2, 2026. Five limits are specific to this audit. First, the roster expanded before the recent audits — from 85 managers (83 filing) to 149 (147 filing) — so "of 147" counts are not comparable to earlier pieces' "of 83" figures. Second, this name carries a single CUSIP (857477103) and no option rows appear in either the tracked collection or a second full-market CUSIP, so no put/call separation is needed anywhere in this audit. Third, the full-market reported value implies a price below the June 30 close (-3.59%); the gap is printed as found and filer and share counts are headlined. Fourth, the congressional aggregates carry a row whose member field is zero while recording one sale transaction; the row is reported exactly as it stands in the files, and no member, party or purchase date is inferred from it. Fifth, the TipRanks screener listing (snippet dated October 16, 2026) postdates the 13F snapshot and the short-interest series; the listing is known to this audit only from outside coverage, not from our own files, and none of its price figures are cited here; every price figure here is from our own price file.
• Superinvestor lens: 147 managers in the collection (of a 149-manager roster; 144 at a June 30, 2026 period-end and 3 early filers at September 30, 2026, none of them holding this name) collected directly from SEC EDGAR Form 13F (managers_13f collection, regenerated October 15, 2026 for the expanded roster); State Street positions are counted on CUSIP 857477103, long rows only. Seven distinct managers hold long positions, all at June 30, 2026, totalling 6,979,936 shares worth $1,183,799,812, with a direction count of 4 DECREASED, 2 NEW and 1 INCREASED, and no option rows. Bill Nygren - Oakmark Funds' share of the stake is 68.3% = 4,765,306 / 6,979,936; GQG Partners' is 15.8% = 1,106,046 / 6,979,936; Yacktman Asset Management's is 13.2% = 919,740 / 6,979,936; Christopher Davis - Davis Advisors' is 2.1%; Dodge & Cox Funds' is 0.5%; Guinness Asset Management's is 0.1%; Richard Pzena - Pzena Investment Management's is 0.0%; the top two together are 84.1% of the stake. All five continuing holders verify row by row against the first quarter under the rule used in the previous audits — a holder's first-quarter row accepted only when it sits under the same filing-agent prefix as the manager's second-quarter accession and its implied shares-change reproduces the EDGAR shares-change label at one decimal place — so the verified continuing total is 10,718,321 shares at March 31 moving to 5,872,659 at June 30 (-45.2%), with no unverified holder. The NEW-label register cross-check was run for both NEW holders: neither GQG Partners nor Richard Pzena - Pzena Investment Management has a first-quarter register row for this CUSIP under its second-quarter filing prefix, so both NEW labels match the register and both entries are genuine; the two new holders total 1,107,277 shares. The early-filer cross-check has no case to run — no September 30 holder exists for this name — and passes vacuously. The pipeline register reconciles in both quarters with no residual (first quarter: 5 rows and 10,718,321 shares, equalling the verified continuing total; second quarter: 7 rows and 6,979,936 shares, equalling the verified continuing total plus the new holders, 5,872,659 + 1,107,277; the register change is -34.9%). Implied per-share value: all seven rows imply exactly $169.60, the June 30, 2026 close, so the cohort implied price is $169.60, 0.0% against the close. No tracked manager exited.
• Full-market lens: SEC Form 13F Data Sets full-market aggregation. The primary table is the full13f collection's by-ticker file (holders = distinct filers reporting the ticker's CUSIP; 1,252 reported long positions out of 1,257 filers). State Street carries a single CUSIP in this aggregation (857477103), and the backfill fixtures' by-CUSIP row matches the by-ticker row exactly on every field — holders (1,257), long holders (1,252), shares (250,132,983), reported value ($40,900,751,503), prior holders (1,117) and prior reported value ($26,996,283,865). The by-ticker file's entered/exited fields (1,089 and 949, a net of +140 that matches the change in holder count) are gross flows, so this audit headlines the net change. Reported-value caution: the aggregate value ($40,900,751,503 over 250,132,983 shares) implies $163.52 per share against a June 30, 2026 close of $169.60 in our price file, a gap of -3.59% — printed here as found. The aggregate sums the VALUE of every information-table row — including put and call option rows — while the share count covers long common-stock rows only, so we headline filer and share counts and label dollar values "reported."
• Insider lens: full-parse Form 4 aggregation (agg_by_ticker), record as of October 2, 2026 (138 filings). Sale and purchase counts are transaction-code counts (S and P) in non-derivative rows; grants and exercises are not counted as purchases, and one filing can contain many transaction rows. The 90-day window (July 5 to October 2, 2026) holds 0 purchase transactions and 4 sale transactions (30,334 shares, $5,588,538.08, 0 buyers, 4 sellers, 4 officer sale transactions) across 9 filings. The one-year window (October 3, 2025 to October 2, 2026) holds 1 purchase transaction (2,500 shares, $312,475.00, 1 buyer, 0 officer purchase transactions) and 18 sale transactions (143,534 shares, $21,098,012.36, 8 sellers, 18 officer sale transactions) across 68 filings. The full record holds the same 1 purchase transaction and 38 sale transactions (323,204 shares for $39,280,669.10 by 12 sellers with 34 officer sale transactions). The site's insider aggregate (90-day window, as of October 18, 2026) carries a row for this name that matches the full parse's 90-day window (site: 0 purchases, 4 sales, $5,588,538.08, 4 sellers; insider_site_match_w90=true) — no mismatch to flag for this name. Window price checks on our price file: the purchase implies $124.99 per share, inside both the one-year close range ($111.00 to $194.26) and the full-period range ($59.84 to $194.26); the 90-day sales imply $184.23, inside the 90-day close range ($174.59 to $194.26); the one-year sales imply $146.99, inside the one-year range; the full-record sales imply $121.54, inside the full-period range — so dollar totals are cited for every window.
• 13D/G lens: full-parse SC 13D/G parsed filings (5 filings matching issuer CIK 93751 on CUSIP 857477103: 3 SC 13G and 2 SC 13G/A, 2 of them amendments, no SC 13D), filings through August 6, 2026. The site aggregation carries this name under a ticker-keyed row; that row (5 filings, 0 D-filings, 5 G-filings, 2 amendments, 5 reporters, latest date August 6, 2026, maximum 13.04%, total reported 101,596,123.78 shares) matches the parsed filings on filings, form mix, amendments, latest date, maximum and the cross-date reported total. The total sums reporter rows across filings and dates (6 reporter rows), so it is a filing-volume total, not a stake — and within the latest filing, FMR LLC and Abigail P. Johnson each print the same 13,854,212.89 shares, so that filing contributes the same shares twice to the total. The filings are reported as filed, under the names exactly as they appear: The Vanguard Group printing 37,212,748 shares at 13.04% as of June 30, 2025 (filed July 29, 2025, SC 13G/A — the register maximum) and 0 shares at 0.0% as of March 13, 2026 (filed March 27, 2026, SC 13G/A); Vanguard Capital Management printing 20,493,476 shares at 7.35% as of March 31, 2026 (filed April 30, 2026, SC 13G); Vanguard Portfolio Management printing 16,181,474 shares at 5.8% as of March 31, 2026 (filed April 29, 2026, SC 13G); and FMR LLC and Abigail P. Johnson each printing 13,854,212.89 shares at 5.0% as of June 30, 2026 (filed August 6, 2026, SC 13G — the latest filing). The parsed coverage for this issuer holds these 5 filings; a 5% holder that has not filed in the covered window would not appear here.
• Congress lens: Senate PTR archive and House PTR archive as maintained on this site. The combined record (as of October 3, 2026) carries a row for this name (0 members listed in the row, 0 purchase transactions, 1 sale transaction, no last-purchase date, no party recorded); the House aggregate (as of October 3, 2026) carries the identical row; the Senate aggregate (as of October 1, 2026) carries no row. The identical combined and House rows mean every recorded transaction for this name sits in the House archive as we hold it, and the Senate absence is recorded as it stands: no recorded Senate transaction for this name sits in that archive. The zero member field is printed as it stands in the aggregate; no member is inferred from it.
• Short interest lens: FINRA Equity Short Interest files (biweekly settlement dates), collected directly from FINRA's public distribution. The published series covers all 137 settlements under the symbol from January 15, 2021 (5,493,415 shares) to September 15, 2026. Every settlement row under the symbol is this issuer's row, under a single issuer-name variant across the file vintages — "State Street Corporation" on all 137 settlements (January 15, 2021 to September 15, 2026, with an NYSE market-class code), recorded as printed; there are no other-issuer rows under the symbol. The latest reading is 5,247,276 shares on September 15, 2026, up 12.33% from the prior settlement (4,671,416 on August 31, 2026), down 19.9% from the series maximum of 6,554,892 on March 31, 2021 and up 4.6% from the June 30, 2026 reading of 5,016,917, at 3.51 days to cover. Series discontinuity check — none found: no single-settlement step at or above 2 times occurs in the series; the largest step is a ratio of 1.59 on March 31, 2022, when the print rose from 2,751,890 (March 15, 2022) to 4,376,591, and the smallest step ratio and the full series are published as collected, with no smoothing or rebasing. The series minimum is 2,198,464 shares on January 12, 2024. The recent path runs 5,016,917 (June 30), 5,064,704 (July 15), 4,853,653 (July 31), 4,648,897 (August 14), 4,671,416 (August 31) and 5,247,276 (September 15). FINRA publishes each settlement about two weeks after the fact, so the October price action is not yet in this series. The share-count ratio (1.91%) uses the fundamentals file's shares-outstanding figure below.
• Fundamentals note: our fundamentals collection carries State Street's revenue of $13,944,000,000, net income of $2,945,000,000 and assets of $366,047,000,000 — all three labelled fiscal 2025 in the file and all sourced to the same financial-series cache, so there is no vintage split to flag. The file is marked ok for this name, with no missing fields: shares outstanding of 274,701,765 (sourced in the file to the shares-outstanding count as of July 28, 2026, from the entity common-stock shares-outstanding line) and a file-computed market value of $48,278,835,198.75. The file does not flag the issuer as a foreign private issuer, and it carries SIC 6022, State Commercial Banks, and an NYSE listing. The file's price for the name is $175.75 as of October 6, 2026; our daily-close file ends October 2, 2026 at $175.96, and we keep the two files' figures separate rather than blending them.
• Prices: our own daily-close file for STT through October 2, 2026 ($175.96 close, +36.4% year to date on that file; the 252-session closing high is $194.26 on September 4, 2026, so the last close sits 9.4% below it; the 252-session closing low is $111.00 on October 10, 2025, so the last close sits 58.5% above it; closes of $126.56 at March 31, 2026 and $169.60 at June 30, 2026, a second-quarter change of +34.0%; change from June 30 to October 2 of +3.8%; change from the September 30, 2025 close of $116.01 of +51.7%; change from the October 2, 2025 close of $115.12 of +52.8%; the December 31, 2025 close is $129.01; the September 30, 2026 close is $174.59).
