- Description: Authorizations disclosed around 10 November total roughly $7.9B — Costco's $4B reauthorization and Steel Dynamics' additional $3.0B lead — while the insider digest printed zero new open-market purchases for a second straight day, a $26.59M Arista sale, and TSMC's cluster still forming at two buyers.

Corporate boards spent the last two days doing loudly what corporate insiders would not do at all. The capital-return tracker logged **seven buyback authorizations disclosed around 10 November totalling roughly $7.9 billion in stated size** — while the insider digest for 11 November recorded, for the second consecutive day, **zero new open-market purchases** by executives and directors across the tracked universe. The two tapes are telling opposite stories about the same prices.

## The authorization wave

- **Costco (COST) — $4 billion reauthorization** of its common-stock repurchase program, announced 10 November alongside its dividend declaration (the dividend itself unchanged at $1.47 per share quarterly). A reauthorization rather than a new program — the board renewing a standing tool at full size.
- **Steel Dynamics (STLD) — an additional $3.0 billion** authorization, announced 10 November in the same release as its fourth-quarter dividend. "Additional" is the operative word: the steelmaker is topping up an existing program, not starting one.
- **Graco (GGG) — $600 million accelerated share repurchase**, an ASR agreement with Bank of America dated 10 November. An ASR is the fastest form of buyback: shares retire on an accelerated schedule rather than dribbling through open-market purchases.
- **Sonos (SONO) — $150 million** new program, announced with the completion of its previous one; **Healthpeak (NHP) — $100 million**, authorized by its board on 4 November and disclosed in this window; **Castellum (CTM) — $6 million**, small in dollars but a meaningful fraction of a small capital base.

Dollar-weighted, this is a big-company wave: Costco and Steel Dynamics alone are $7.0 billion of the $7.9 billion total. Authorizations are permissions, not purchases — history says the cash deploys over quarters, and some of it never deploys at all — but the direction of boardroom intent is unambiguous.

## The silent tape

Against that, the insider side of the ledger is not merely quiet but empty at the top: **no new open-market insider purchases at all** in the 11 November digest, matching the zero printed on 10 November. What the tape does show runs the other way:

- **Arista Networks (ANET): a $26.59 million notable sale** across two tranches, the largest single insider disposition in the tracked universe this week — roughly double the $12.96 million Arista sale flagged the day before.
- **Microsoft (MSFT): a $3.22 million C-suite sale** tripping the notable-sale filter, with Netflix also flagged by the filter in the same run.
- The one forming cluster remains **Taiwan Semiconductor (TSM)**: two buyers, $371,000 of open-market purchases inside the rolling window — a cluster still one buyer short of the three-insider threshold the digest requires before it calls anything a cluster.

## Reading the split

Boards and insiders are different buyers with different information. A board authorizing a buyback is making a capital-allocation statement — often mechanical, frequently pre-planned, and sized against cash flow rather than conviction about next quarter. An insider buying with personal money, in the open market, on the record, is the rarest and cleanest bullish signal the tape offers — and for two straight days it has not appeared once, while $7.9 billion of board-level buying power was announced around it. Yesterday's edition of this tension had the buyback wave at $4.37 billion; it has now nearly doubled, and the insider side has not moved at all. When the two tapes disagree, the honest summary is the one the data keeps printing: institutions are content to retire shares at these prices; the people inside the companies are, for now, content to watch.
