Activism Heats Up as Smart Money Quietly Rotates

A quietly eventful week on the activism front — the marquee stories are a founder pressing for resolution at lululemon and Ackman's methodical accumulation approaching the point of no return at Howard Hughes. The broader institutional flow picture meanwhile tells a striking story about where smart money is quietly rotating.

The week's marquee move

Dennis Wilson tightens his grip — and extends an olive branch — at lululemon. The yoga-apparel brand's founder raised his stake to 8.7% (up from 8.3% across 13 filings dating back to December 2024) and simultaneously signaled he wants a negotiated settlement, not a war. A May 18 press release showed Wilson publicly endorsing eight key terms the company proposed — while pushing back on the exclusion of customary settlement provisions such as replacement director rights and expense reimbursement that appear in at least 14 of the last 20 comparable activist resolutions. The tone has shifted from last December's hostile posture — when McDonald's surprise CEO departure had Wilson calling for board refreshment and succession oversight — to something closer to a handshake in progress. A deal or a proxy fight deadline is likely the next catalyst here.

Also worth knowing

Ackman keeps buying Howard Hughes, now sitting at 47%. Pershing Square's stake has grown by more than 9 percentage points across 11 filings since January 2025, with the latest amendment filed just 28 days ago. At this pace, a majority position is a matter of when, not whether; the structure of any eventual take-private or recapitalization will be the question to watch.

Casdin Capital has been quietly exiting BioLife Solutions. The life-sciences tools fund filed a 13D/A five days ago showing its stake more than halved — from 18.5% down to 9.7% over six filings — while flagging strategic alternatives in its intent. That's a meaningful stake reduction by a sector-specialist, and it warrants attention from anyone following the bioprocessing supply chain trade.

Deeper look — where institutional money actually moved last quarter

Stepping back from the wire: the dominant flow story of the most recent quarter is a large-scale rotation out of mega-cap tech and into energy and power infrastructure. Smart-money funds collectively pulled roughly $57 billion out of Microsoft and $46 billion out of Nvidia in net selling — not because they abandoned the names (both still carry over 400 notable holders), but because positioning had grown too heavy. On the other side, Canadian Natural Resources drew over $6 billion in net inflows from 150 notable buyers, and Constellation Energy attracted nearly $6 billion with 27 new notable fund entrants — a signal that the AI power-demand theme is being expressed through the grid, not the chip stack. Banks also featured: Fifth Third and Huntington together absorbed nearly $9 billion in combined net inflows, suggesting a quiet regional-bank re-rate trade is underway beneath the surface.

What we're watching

Lululemon settlement clock. Wilson's public endorsement of the company's framework suggests a deal is close — watch for a definitive agreement or a board seat announcement in the next few weeks.
Ackman at Howard Hughes. The next 13D/A will tell us whether he crosses 50%; that threshold likely triggers structural decisions about the company's future.
REH Advisors / HF Sinclair. A trimmed stake (7.6% → 6.3% over 4 filings) alongside a stated board-representation intent is an unusual combination — watch whether this resolves into a settlement or a quiet exit.

For information only, not investment advice. 13D/13G filings appear approximately 10 days after the activist crosses 5%; 13F position data is 45 days delayed. Track records, where referenced, are a 13F-replication proxy of disclosed long positions — not audited fund returns.
