About Stanley Druckenmiller
**Stanley Druckenmiller – Duquesne Family Office**
Stanley Druckenmiller manages Duquesne Family Office, the private investment vehicle he established following the closure of Duquesne Capital Management in 2010. As of the Q1 2026 13F filing, dated May 15, 2026, the reported portfolio holds $3.4 billion in assets distributed across 68 disclosed positions. The portfolio is characterized by a sector rotator style, reflecting a pattern of frequent repositioning across asset classes and industries over successive quarters.
The latest filing discloses a concentrated top-tier structure, with the five largest positions accounting for 42.1% of total portfolio value. Natera Inc. (NTRA) represents the single largest holding at 18.1%, followed by iShares Inc. (ETHB) at 8.7%, Insmed Inc. (INSM) at 5.6%, Taiwan Semiconductor Manufacturing (TSM) at 5.0%, and Invesco Exchange Traded Fund Trust (IVZ) at 4.7%. The portfolio's largest reported sector classification is Unclassified, which accounts for 87.9% of disclosed holdings — a figure consistent with significant exposure to ETF vehicles and instruments that do not map cleanly to standard GICS sector categories.
Quarter-over-quarter activity in Q1 2026 reflects substantial portfolio reconstruction. Duquesne Family Office disclosed 31 new positions initiated during the period, alongside 23 full exits. An additional 12 positions recorded increased sizing, while 19 positions were reduced. The combined volume of new entries and full exits — 54 changes in total — is consistent with the active rotation profile observed across prior filings from this investor.

Bets on sectors more than specific names; rotates as themes shift.
The portfolio holds 68 positions valued at approximately $3.4 billion, with moderate concentration where the top five positions account for 42.1% of the total, while a low HHI score of 5.9 reflects relatively even distribution across the remaining holdings. A high sector tilt score of 77.7 combined with annual turnover of 54% characterizes a portfolio that rotates meaningfully across sectors, though 75.6% of positions are carried over quarter-to-quarter, indicating a mix of stable core holdings and active reallocation. AI and technology exposure is limited at 11.9%, suggesting the portfolio spreads across a broader range of sectors rather than concentrating in that theme.

Recent allocation changes include reductions in inflation-sensitive positions (IAU), with increased weight in defensive and long-duration assets. This shift in positioning is consistent with reduced near-term inflation concern as implied by observable portfolio weights. Dollar-sensitive positioning — including exposure to short-duration domestic assets and limited international/commodity allocation — reflects a relative dollar-strength signal from observable holdings.

Opening a new position can suggest the manager sees value or a thesis worth committing capital to. It does not necessarily mean they are bullish on the broader market — concentrated managers add positions infrequently while quants may rotate constantly.

Adding to an existing position may indicate higher conviction, scaling into a thesis, or rebalancing toward a target weight. It does not necessarily mean the position is undervalued at the current price.

Trimming a position may suggest portfolio rebalancing, profit-taking, or risk management. It does not necessarily mean the manager has turned bearish on the underlying company.

Fully exiting a position can suggest that the manager's thesis has played out, was wrong, or that capital is being redeployed elsewhere. It does not mean the company is broken — exits are often as much about portfolio fit as about the security itself.
