Bottom line: the highest-information corporate ownership disclosure in the latest 30 days is NVIDIA's 9.3% beneficial ownership of Nebius. However, the SEC filing says most of it comes from a pre-funded warrant acquired on March 11—not a purchase on July 13. After stock-split and corporate-action adjustments, NVDA, JNJ and SNOW were net adds for five of the six Q2 early filers.
The timing distinction is essential. Schedules 13D/13G disclose beneficial ownership events such as crossing a 5% threshold and are generally more timely; 13F compares quarter-end portfolios. This report uses both but keeps them in separate tables and never treats event date, filing date and acquisition date as interchangeable.
Treat this as an idea-generation map, not an automatic buy list. Current valuation, earnings revisions, technical entry points and short exposure are outside the filing data. The sensible next step is to research high-consensus names now and rerun the screen after the full August filing deadline.
Filed in the last month does not mean bought in the last month
After stock-split and corporate-action adjustments, NVDA, JNJ and SNOW were net adds for five of six comparable Q2 early filers. AI infrastructure and defensive assets appeared together rather than as a one-factor risk-on trade.
Focus: strategic and large beneficial ownership from Schedules 13D/13G
The 30-day SEC index contained 1,312 unique 13D/13G accessions, including 456 initial, non-amended filings. The table below curates high-information cases involving well-known corporations or a major bank. Schedule 13G generally denotes passive ownership, while Schedule 13D may involve control or governance; neither automatically proves an open-market purchase.
| Filer → issuer | Filed / event date | Beneficial ownership | What it actually means | Signal |
|---|---|---|---|---|
| NVIDIA → Nebius (NBIS) Schedule 13G | Jul 20 / Jul 13 | 22,256,412 shares · 9.3% | 1,190,476 shares were already in NVIDIA's Q1 13F; the other 21,065,936 are underlying a pre-funded warrant acquired March 11. The warrant entered the 60-day beneficial-ownership window on July 13. This was not a 22.3m-share purchase on July 13. | High strategic value timing needs correction |
| Palantir → Surf Air Mobility (SRFM) Schedule 13G | Jul 1 / Jun 24 | 8,248,989 shares · 7.4% | An initial 13G confirms passive beneficial ownership above 5%. The filing does not provide cost basis, and the event date alone does not prove a same-day purchase. | Strategic watch |
| Renesas → SiTime (SITM) Schedule 13D | Jul 9 / Jul 1 | 3,558,691 shares · 11.9% | Renesas sold its timing business to SiTime for about $1.5bn cash plus these shares and gained a board nomination right. The stake was transaction consideration, not open-market buying. | High industrial logic |
| JPMorgan → ALGM / MKSI / KLIC / VICR four Schedules 13G | Jul 16 / Jun 30 | ALGM 6.8%; MKSI 5.0%; KLIC 5.0%; VICR 6.9% | The bank and its accounts crossed passive 5% ownership thresholds. This is useful position-size evidence, but it is not a JPMorgan corporate strategic investment or proof of concentrated July buying. | Institutional ownership |

1. Strongest cross-manager signals
Direction is based only on reported share-count changes in ordinary long equity positions. Estimated added notional equals added shares multiplied by quarter-end reported value per share. It is a proxy, not execution value or cost basis.

2. What each core manager changed
| Manager / filed | Q2 disclosed value | Raw New / Add | Representative adjusted initiations or adds | Quality note |
|---|---|---|---|---|
| Swedbank Jul 15 | $115.99bn | 44 / 326 | SpaceX new $609m; AMD +$521m | Holdings report; 2 other managers; KLAC is a reduction after split adjustment |
| Assenagon Jul 8 | $80.18bn | 176 / 461 | SNDK new $1.41bn; NVDA +$1.17bn; UBS +$808m | Large multi-strategy portfolio |
| Congress Asset Management Jul 7 | $16.25bn | 32 / 150 | ARM new $145m; KLIC new $117m; MIR +$100m | Normal early Q2 holdings report |
| ATP Jul 17 | $4.60bn | 18 / 107 | DAL new $32.2m; MRK new $30.6m; MTB new $30.2m | Danish supplementary pension fund; KLAC is a reduction after split adjustment |
| Avanza Fonder Jul 17 | $4.59bn | 13 / 246 | MSFT +$33.3m; AMZN +$31.1m; AAPL +$28.3m | Substantial indexed/fund exposure; KLAC is a reduction after split adjustment |
| Mitsubishi UFJ Morgan Stanley Securities Jul 15 | $32.7m | 10 / 12 | AMAT +$3.2m; AVGO +$2.2m; MRVL new $0.82m | Small portfolio; used as direction confirmation |
Raw New / Add counts are not fully corporate-action-adjusted and only describe turnover; they are not a buy count. Leading securities in the main screen and figures were checked for splits and identifiable CUSIP migrations. ETFs, convertibles and options still require security-level review.
3. Major banks, brokers and famous managers: Q2 still pending
| Major bank / broker | Latest main 13F | Largest Q1 net adds vs restated Q4 | Q2 status | Interpretation note |
|---|---|---|---|---|
| JPMorgan Chase | 2026Q1 · May 13 restatement | GOOG +$5.25bn; META +$3.39bn; MRK +$2.81bn | Pending | Restatement replaces original filing |
| Goldman Sachs | 2026Q1 · May 15 | MSFT +$3.63bn; NVDA +$2.46bn; GOOG +$2.36bn | Pending | High turnover and client exposure |
| Morgan Stanley | 2026Q1 · May 15 | AAPL +$3.55bn; NVDA +$3.35bn; AMZN +$2.57bn | Pending | Combination; Q4 uses later restatement |
| Bank of America | 2026Q1 · May 18 | JPM +$2.63bn; META +$1.53bn; BMY +$1.06bn | Pending | Consolidated firm and client accounts |
| Citigroup | 2026Q1 · May 11 | NVDA +$2.26bn; MSFT +$1.79bn; AAPL +$1.59bn | Pending | Not suitable for copy-trading |
| UBS Group | 2026Q1 · May 5 | MSFT +$1.85bn; AAPL +$1.39bn; TSM +$1.26bn | Pending | Combination; large client component |
| Nomura | 2026Q1 · May 15 | TECK new $377m; CTSH +$275m; WBD +$132m | Pending | Combination report |
Bank comparability QC: JPMorgan and Morgan Stanley had relatively stable reporting boundaries. Included-manager counts changed at Goldman, Citi, UBS and Nomura, while Bank of America's table-row count fell sharply. False AstraZeneca initiations caused by a CUSIP migration were removed. All estimates describe consolidated firm/client quarter-end positions, not proprietary trading.

Well-known corporate investment filers
| Corporate filer | Latest disclosed value | Representative change | Quarter status |
|---|---|---|---|
| Japan Post Holdings | Q2 · $5.97bn | Only AFL; reduced by 1,076,010 shares, no New/Add | Q2 filed |
| Glencore | Q2 · $4.87bn | Bunge and Century Aluminum share counts unchanged, no New/Add | Q2 filed |
| SoftBank Group | Q1 · $11.4bn | Ethos Technologies new ~$34.9m | Q2 pending |
| Markel Group | Q1 · $11.9bn | Sunbelt Rentals new $62.7m; MELI new $9.4m | Q2 pending |
| Loews | Q1 · $11.9bn | TEAM +$43.7m; BLDR +$37.9m; AMZN new $29.2m | Q2 pending |
The “well-known company” category only includes corporate entities that actually have a Form 13F filing obligation and a comparable securities portfolio. Famous public companies such as Apple or Tesla do not automatically file 13F simply because they are well known.
4. Portfolio message: offense and defense coexist
The broadest consensus spans offense and defense
NVDA, JNJ and SNOW reached 5/6. GOOGL, AVGO, MU and COHR reached 4/6 alongside defensive PEP, WMT and PG. The early sample is not a one-factor AI or risk-on basket.
Equal votes do not mean equal capital
MUMSS reports only about $32.7m versus Swedbank's roughly $116bn portfolio, yet each manager receives one breadth vote. Breadth must be paired with estimated notional and manager concentration.
Initiations deserve extra diligence
Congress initiated ARM, KLIC and MU; Assenagon and Avanza initiated SNDK; multiple managers initiated SNOW. Corporate actions, CUSIP changes and reporting-scope changes still need to be ruled out.
The complete answer arrives after mid-August
Many large managers file close to the deadline. This is a first-pass radar, and the consensus screen should be rerun after August 14.
5. How to use the screen
- Good for: discovering institutional consensus, finding initiations, building sector watchlists and validating durable themes.
- Not good for: timing entries, inferring actual cost basis, observing equity shorts or estimating net exposure.
- Next update: rerun after the August 14 deadline and add valuation, estimate revisions and price performance.
6. Method and safeguards
| Step | Method | Reason |
|---|---|---|
| Filing universe | SEC master index; Jun 22–Jul 21; 13F-HR and 13F-HR/A | Separates filing date from report date |
| Core sample | Original Jun 30 13F-HR filings with an adjacent Mar 31 filing | Excludes old-period amendments and delayed disclosures |
| Aggregation key | CUSIP + put/call + SH/PRN | Avoids issuer-name and class-text drift |
| Direction | New/Add/Reduce/Exit based on ordinary-long share counts | Market-value changes include price movement |
| Corporate actions | Adjust stock splits and map verifiable CUSIP migrations before comparing quarters | Prevents mechanical share-count changes from becoming false trades |
| Options | Excluded from the main ranking | 13F lacks strike, expiry, cost and delta |
| Quality control | Flags amendments, confidentiality, combination reports and other managers | Scope changes can create false buys |
