What it reported after the quarter end (Q2 2026)

The 13F shows the portfolio as of Jun 30, 2026. Since then Sio Capital Management has filed these own trades with the SEC (Form 4, when it owns more than 10% of a company or holds a role in it) and stakes above 5% (13D and 13G). It is not everything it did: only what it must report before the next 13F.

What changed this quarter

73 positions with a change (14 new, 9 added to, 21 trimmed, 29 sold); also, 1 exited through an acquisition or merger. 12 are listed here: those of 0.5 points of the portfolio or more (up to 12).

The figure on the right: for positions added to or trimmed, the change in the number of shares (%); for new and sold ones, the points of the portfolio moved (pp). Below, the portfolio weight before → after. Traded weight: what it bought or sold, excluding price effects.

Top holdings

“Since”: first quarter of the current run, unbroken until today. In the details, prices are the quarter-end prices of the quarters in which it added shares, per the 13F. The manager may have bought at any price within each quarter; the SEC only publishes the value at quarter end.

Traded turnover: the weight it bought plus the weight it sold in the quarter, divided by two, excluding price moves. The plain “turnover” in the header does include that effect. With a free account: the full history and sectors over time.

Declared options (2)

Besides stocks, Sio Capital Management declared 1 put (they gain if the stock falls) and 1 call (they gain if it rises) with a notional of $20.8M. The 13F reports the value of the underlying shares, not the premium paid, so these figures look large and are not added to the portfolio. Nor does it say whether the option is bought or written, or its strike or expiry: it may be a hedge.

Stakes above 5% (13D/13G)

Companies where this filer reported holding 5% or more of the shares. It is the figure from its latest filing on each one; history since December 2024.

How we classify it

Investment firm, per its Form ADV of Mar 18, 2026 (high confidence).

The data, as reported: SIO CAPITAL MANAGEMENT, LLC (CRD 165989): 7.B private funds: 2 hedge (gross assets $685M); 5.D assets by client type: pooled vehicles 53%, other advisers 47% (of $1.3 bn)

The type comes from a rule applied to that data. If it looks wrong, tell us.

Similar managers by type and size

Same type of filer and a 13F portfolio value between a third and three times this one. It is not a comparison of what they hold.
