Portfolio structure and a look to the future
The updated data for December 31, 2025, shows that despite the broad diversification, the fund is not afraid to make sharp adjustments to its core holdings.
While it significantly increases exposure to giants like $COST and $TSLA, it chose to divest from most of its $NVDA holding, perhaps due to an assessment that the short-term upside potential has been exhausted.
The current investment mix presents a combination of high-growth technology and stable consumer companies, a strategy that attempts to balance risk and return under current market conditions.
