Key Holdings

The portfolio is dominated by large-cap technology and ETF exposure, with a strong emphasis on the artificial intelligence (AI) infrastructure trade.

  • INVESCO QQQ TR (QQQ): This is the largest holding, accounting for 10.71% of the portfolio ($7.28B). It was established as a new position this quarter, signaling a strategic shift to gain broad-based exposure to the Nasdaq-100 rather than selecting individual winners exclusively.
  • NVIDIA (NVDA): Despite a reduction of 10.6% (selling $199M worth of shares), NVDA remains the second-largest holding at $3.80B (5.59%). This indicates continued conviction in the primary AI semiconductor beneficiary, even while taking some profits.
  • Tesla (TSLA): TSLA is the third-largest position ($2.82B). The firm reduced this stake by 14.6% ($461.74M), potentially trimming exposure after a strong run or rotating capital into other growth areas.
  • CoreWeave (CRWV): A standout position is CoreWeave, a specialized cloud provider for AI workloads. The firm aggressively increased this position by 1,548.1%, adding $1.83B. CRWV now represents 2.91% of the portfolio, highlighting a high-conviction bet on the "picks and shovels" of the AI industry.
  • Strategy (MSTR): The firm opened a massive new position in Strategy (formerly MicroStrategy) worth $982.73M, representing a significant bet on Bitcoin exposure through a corporate proxy.
