    Semiconductor stocks extend 10% weekly decline on geopolitical risk

    Question

    Semiconductor stocks extend 10% weekly decline on geopolitical risk

    Direct answer

    The semiconductor sector is facing a 'perfect storm' of high valuations, geopolitical instability, and concerns over AI capex sustainability. Despite Nvidia's 140% YoY earnings growth and dominant market share, the SOXX index is down 10% this week as traders reduce exposure ahead of the Federal Reserve's policy decision. The competition between Apple and Nvidia for the $5T valuation mark highlights the concentration of the current market, where a few names dictate the direction of the broader indices.
