Key Holdings

The portfolio is characterized by high conviction in its top names, with the largest positions commanding significant weightings.

  • Cameco Corp (CCJ): This is the dominant holding, accounting for 19.86% of the portfolio ($72.37M). Arosa holds 863,000 shares, indicating a strong bet on the uranium and nuclear fuel sector.
  • Talen Energy Corp (TLN): The second-largest position at 12.15% ($44.26M), reinforcing a focus on power generation and utilities.
  • ETF Liquidity: Notably, the firm holds the SPDR S&P 500 ETF (SPY) and the Industrial Select Sector SPDR (XLI) as the 3rd and 4th largest positions, comprising roughly 21.5% of the portfolio combined. This suggests a desire to maintain liquidity or broad market exposure while actively managing specific stock picks.
