Buying compute fear while holding concentrated platform stock positions

The author is aggressively buying IREN and CRWV into the selloff, arguing that AI infrastructure fear is excessive because compute demand keeps rising. GOOGL is the largest disclosed position, alongside a multimillion-dollar UBER holding. Late in the window, the author reports increasing IREN to 71,250 shares and separately recaps a quick profitable NBIS flip.

Direction this week

The author treats the compute selloff as a buying opportunity, explicitly adding IREN and CRWV on October 14 and reporting a larger IREN holding of 71,250 shares on October 15. IREN accounts for 50% of the compute theme's signals, warranting concentration and pump-risk monitoring; GOOGL remains the largest disclosed portfolio position, while the NBIS activity is a completed quick-profit trade.
