The semiconductor sector is experiencing a significant selloff, with the SOXX ETF down -4.20%. The decline is primarily attributed to disappointing forward-looking guidance from key industry players like Lam Research, which overshadowed strong current earnings. Concerns are also mounting about the sustainability of the artificial intelligence (AI) infrastructure boom, fueled by Meta's increased spending outlook and Tesla's capital expenditure cuts, leading to investor anxiety about future profitability. Broader market weakness in the tech sector is exacerbating the selloff in these high-beta stocks.
