RESEARCH — THE FILING TAPE #79

Three of 83: Ariel Is 90.2% of the Superinvestors' Hewlett Packard Enterprise Stake. Its Insiders Have Never Bought a Share.

October 15, 2026

GetCoattail Research — The Filing Tape #79. Hewlett Packard Enterprise fell about 5.1% on October 14 in Barron's account of a Barclays downgrade, and the filings describe a three-name tracked cohort that cut its stake 52.04% in the second quarter, a full market that added 149.8 million shares, an insider record with zero open-market purchases, no congressional record at all, and a borrow 41.0% below its January 2026 peak.

The Hype

Hewlett Packard Enterprise became a market story on October 14 for the wrong reason. Barron's market-movers coverage recorded the shares down about 5.1% that day, after Barclays cut its rating on HPE — and on Dell and NetApp as well — to Equal Weight from Overweight, judging that no meaningful AI inflection had arrived yet. Barchart's movers summary of the same session likewise put HPE down more than 4%, Dell down more than 6% and NetApp down more than 2% on the downgrade. The cut landed on a stock that, in our own daily-close file, had already run hard: the file ends earlier, on October 2, at $69.33 — itself the 252-session closing high, up 188.6% year to date on that file, after an 89.5% rise in the second quarter alone. The filings below ask a prior question: who held the stock before the downgrade was written.

The Tape

For Hewlett Packard Enterprise — the seventy-ninth Filing Tape audit — the tape shows a three-name tracked cohort whose share count fell 52.04% in the second quarter even as the full market added 149,752,865 shares, an insider record containing no open-market purchase at all against 41 sales, no congressional record in any aggregate, a 5% register that is entirely passive filings peaking at 8.9%, and a borrow 41.0% below its series maximum.

Lens 1 — the superinvestors: three holders, and the top one is nine-tenths. We track 83 large, mostly long-only managers whose 13F portfolios we collect directly from SEC EDGAR. As of June 30, 2026, 3 held Hewlett Packard Enterprise long, totalling 832,602 shares worth $37,558,677, with no option rows — every row on the single CUSIP. John Rogers - Ariel Investments holds 751,355 shares worth $33,893,624 — 90.2% of the cohort's position — at a 0.34% weight, and it decreased 54.7% in the quarter. Behind it sit Dodge & Cox Funds (63,450 shares, decreased 17.3%) and Lee Ainslie - Maverick Capital (17,797 shares, new in the quarter). Both continuing holders decreased, one manager entered, and no tracked manager exited. On a cohort basis — each manager's pipeline row matched by its EDGAR total value, with the implied changes matching the collection's labels exactly — the cohort held 1,736,152 shares at March 31 and 832,602 at June 30, down 903,550 shares (−52.04%). Ariel's cut alone, from 1,659,398 shares to 751,355, is 908,043 shares — more than the cohort's whole net decline, partly offset by Maverick's new 17,797-share position. The implied price, $45.11, sits exactly on the June 30 close. 13F figures are as of June 30, 2026; funds have up to 45 days to file, so this picture is complete — and always lagging.

Hewlett Packard Enterprise through six filing lenses
Chart 1: Signal presence by cohort. Superinvestors: 83 managers, 2026Q2 13F (as of Jun 30, 2026). Institutions: full-market 13F aggregation, same date. Insiders: Form 4 through Oct 2, 2026. Congress: PTR records through Oct 3, 2026 — no row for this name. 13D/G: parsed filings through Apr 30, 2026. Short interest: FINRA settlements through Sep 15, 2026. Source: SEC EDGAR; FINRA; GetCoattail collections.

Lens 2 — institutions: 340 more filers, 149.8 million more shares. At June 30, 2026, 1,442 institutions reported positions, up 340 from 1,102 at March 31 (+30.85%), 1,432 of them long. Reported shares rose 14.62%, from 1,024,205,557 to 1,173,958,422 shares. Reported value rose 116.53% to $52,903,999,889; the aggregate includes option rows, so we headline filer and share counts and label dollars "reported" (see methodology). The name reports under a single CUSIP, and the by-CUSIP row matches the by-ticker totals exactly on every field. The full market added shares at a pace the tracked cohort did not join — the cohort's entire position is 832,602 shares, and it shrank by more than half.

Lens 3 — insiders: no purchase in the entire parsed record. The parsed Form 4 record holds 143 filings through October 2, 2026, and zero purchase transactions — in the last 90 days, in the last year, and across the full record — with zero officer purchases in every window. The 90-day window holds 5 sale transactions totalling 325,131 shares and $19,307,415.22, by 4 sellers, 4 of the 5 of them officer sales. Across the last year the record holds 29 sales totalling 1,651,855 shares and $54,008,156.77, by 12 sellers, 25 of the 29 of them officer sales; across the full record, 41 sales totalling 2,371,169 shares and $70,211,718.37, by 13 sellers, 35 of the 41 of them officer sales. The site's own insider aggregate, compiled over the same 90-day window, matches the full parse exactly. We assign no motives; this is a register of sales with an empty purchase column, and this audit describes it as exactly that.

Lens 4 — Congress: no record at all. The combined record (as of October 3, 2026) carries no Hewlett Packard Enterprise row. The House aggregate (as of October 3, 2026) carries no row, and the Senate aggregate (as of October 1, 2026) carries no row either. There is no purchase, no sale, no member and no date to report from our congressional collections for this name.

Lens 5 — the 5% register: four filings, all passive, four reporting names. Our full parse holds exactly 4 SC 13D/G filings — two SC 13G and two SC 13G/A amendments, with no SC 13D-family filing at all — 4 reporting-person rows across 4 names, most recently filed April 30, 2026, matching the site aggregate's ticker-keyed row on every headline field. The register's maximum is BlackRock, Inc. reporting 118,699,078 shares (8.9%) as of December 31, 2025. The remaining rows carry Vanguard reporting names, printed here exactly as filed and not combined: The Vanguard Group reports 0 shares (0.0%) as of March 13, 2026; Vanguard Portfolio Management reports 74,077,721 shares (5.58%) as of March 31, 2026; and Vanguard Capital Management reports 99,882,727 shares (7.52%) as of March 31, 2026. There is no activist filer in this register at all.

Lens 6 — short interest: 55,958,000 shares, well under the peak, above a year ago. As of September 15, 2026 — the most recent of 137 FINRA settlements since January 15, 2021 — 55,958,000 shares were sold short, up 1.18% from the prior settlement. The series maximum, 94,785,356 shares on January 30, 2026 — verified by a maximum query over the whole series — leaves the latest 41.0% below it. The last five settlements read 65,104,946, 65,183,825, 59,572,842, 55,304,252 and 55,958,000. Against the year-ago 46,587,551 shares the latest is up 20.1%; against the June 30, 2026 settlement of 67,772,233 it is down 17.4%. Against 1,327,464,779 shares outstanding, it is 4.22% of the share count, at 1.58 days to cover.

The Gap

The narrative, as the downgrade coverage frames it, is a waiting question: the AI payoff has not yet shown up as a meaningful inflection, so a stock that had risen 89.5% in the second quarter and 53.7% more since quarter-end — on our price file, through October 2 — fell about 5.1% on October 14. The filings describe who held the stock before that question was asked, and the two ownership lenses point in opposite directions. The full market held 1,173,958,422 reported shares at June 30, up 149,752,865 shares (+14.62%), as its filer count rose by 340 to 1,442. The tracked cohort held 832,602 shares and cut 52.04% of them: both continuing holders decreased, the largest holder cut 54.7%, and the quarter's only entry was a new 17,797-share position. The 5% register holds no activist at all — passive filings whose reported maximum, 8.9%, dates to December 31, 2025. Insiders have recorded no open-market purchase in the parsed record against 41 sales, and sold $19,307,415.22 in the last 90 days. Congress has no record for this name in any aggregate. The borrow, at 55,958,000 shares and 4.22% of the share count, is well below its January 2026 peak but a fifth higher than a year ago. One plausible reading is that broad accumulation and a rising price carried the register while the tracked cohort concentrated into a single, shrinking position and the company's own officers sold into the same quarters. The record supports each clause separately; it does not say which side the next quarter favours.

What Would Change the Picture

Nothing above is a recommendation. It is a record. These filings would change the description:

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 through October 3, 2026 (Senate through October 1, 2026); 13D/G through the April 30, 2026 filing; short interest through September 15, 2026; our price file ends October 2, 2026. Two limits are specific to this name. First, the October 14 downgrade — the reason for the search interest — postdates every lens here, and the downgrade-day price move is known to this audit only from outside coverage, not from our own price file, so nothing in the tape yet reflects positioning after it. Second, the congressional lens is an absence in our aggregates, reported as such: our combined, House and Senate collections carry no row for this name.

Six of 83: The Superinvestors Hold Little Tesla — and Cut a Third of It in Q2
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.
