Filer Agreement Splits the Mega-Caps Along the Silicon Line
In the latest 13F window, institutional filers are near-unanimous on Nvidia and Apple and nearly evenly divided on Microsoft and Amazon — and the attention data sits on the same side of the split.
Sterling scan summary
Mega-cap filer agreement is now name-specific: near-unanimous on silicon, nearly split on cloud software.
Why Sterling flagged it
- The 13F rotation check flagged 14 names with at least six filers moving the same direction over the 45-day window; within the six-name top sample, the adder-to-reducer ratios diverge sharply — NVDA 12:2, AAPL 10:1, TSLA 7:1 against MSFT 9:6 and AMZN 9:7.
- The split does not track disclosed size: Apple carries $90.2bn of sampled disclosed value versus Microsoft's $29.9bn and Amazon's $19.8bn, yet the tightly-agreed and the evenly-divided names sit on both sides of that range. Alphabet sits between at 9 adders / 4 reducers.
- News pressure concentration flagged 85 tickers clearing six or more articles in 48 hours, led by NVDA (68) and MU (39) — both on the silicon side of the 13F split, with GOOG (26) the only other mega-cap in the top sample.
- Congressional disclosure produced one qualifying pair in the 14-day window: a JPM buy by three members totalling roughly $48.5k at midpoint. No technology symbol/direction pair qualified.
- No insider buy cluster and no insider sell cluster corroborates the pattern in the 7-day Form 4 window; the sector-breadth check was not evaluated for a historical scan date.
How Sterling got here
- Observation
The 13F check flagged 14 qualifying names. In the six-name top sample, direction ratios are not uniform: NVDA 12 adders / 2 reducers, AAPL 10 / 1, TSLA 7 / 1, GOOGL 9 / 4, MSFT 9 / 6, AMZN 9 / 7. The check's threshold is six filers moving one way; several of these clear it by a wide margin while others clear it only on the adder side with a near-matching reducer count.
- Cross-check
News pressure concentration flagged independently — 85 tickers with six or more articles in 48 hours. Its top sample is led by NVDA (68) and MU (39), with RACE (29), BNO (29), GTLL (38) and GOOG (26) filling the rest. The attention leaders sit on the same side of the 13F split as the tightly-agreed names.
- Independent confirmation
Disclosure data does not corroborate. The only qualifying congressional pair in 14 days is a JPM buy by three members, roughly $48.5k combined at midpoint — outside technology entirely and small in absolute terms. Neither Form 4 clustering check produced a qualifying cluster.
- Inference
The combination implies the mega-cap complex is no longer being positioned as one object, and that the cleanest filer agreement currently sits where attention is heaviest. That is a reversal in composition from earlier Sterling scans this month, when Nvidia drew the window's only disclosed sell cluster; it is not evidence of a directional view on any name.
- Status
What is not corroborated: any insider or congressional confirmation inside technology, any dollar-weighted measure of the 13F split, and any live sector-breadth read. The signal rests on two flagged checks — one lagged and filer-counted, one an attention proxy — and should be treated as a configuration to monitor rather than an established rotation.
What data Sterling analyzed
Sterling's Embedded Intelligence ran six deterministic checks against the 2026-05-26 bundle; three flagged, and only two point the same way.
| Check | Sources | Result | Detail |
|---|---|---|---|
| 13F institutional rotation | 13F filings, 45-day window | FLAGGED | 14 names with ≥6 filers moving the same direction; top sample shows NVDA 12:2 and AAPL 10:1 against MSFT 9:6 and AMZN 9:7. |
| News pressure concentration | Scored news feed, 48-hour window | FLAGGED | 85 tickers with ≥6 articles; NVDA (68) and MU (39) lead the top sample. |
| Congressional trade clustering | STOCK Act disclosures, 14-day window | FLAGGED | One qualifying pair — JPM buy, 3 members, ~$48.5k combined midpoint. |
| Insider buy clustering | Form 4 filings, 7-day window | CLEAR | No qualifying buy cluster. |
| Insider sell clustering | Form 4 filings, 7-day window | CLEAR | No qualifying sell cluster. |
| Unusual sector move | Daily sector breadth (live sessions only) | CLEAR | Not evaluated for historical scans. |
What would confirm
- Marvell (May 27) and Dell (May 28) — results that separate compute-supply demand from enterprise buyer spending would support the split the 13F ratios describe.
- Salesforce (May 27) and Palo Alto Networks (June 2) — software-side prints landing on different terms than the silicon-side prints would reinforce the two-profile reading.
- April Durable Goods Orders (May 28, estimate 3.5% MoM vs 1.3% prior) — a print near or above estimate would be consistent with hardware demand running ahead of the broader spending track.
- Next 13F window — MSFT and AMZN reducer counts holding at or above six while NVDA and AAPL ratios stay above six-to-one would escalate this from configuration to trend.
What would invalidate
- Ratio convergence — MSFT and AMZN reducer counts falling toward the one-to-two range seen on AAPL and TSLA would dissolve the split entirely.
- Attention broadening — the news concentration check leading with names outside silicon would remove the second leg of the convergence.
- A tech disclosure cluster — any qualifying congressional or Form 4 cluster in mega-cap technology would reframe the read around insider and legislator positioning rather than filer composition.
- Common demand driver — Dell and Marvell guidance pointing at the same underlying cycle as the software cohort would favor the mechanical explanation over the primary reading.
