The Nasdaq Composite fell 2.86% on Friday, led by selloffs in Alphabet (down 12%) and Intel (down 28%), exposing concentration risk in tech-heavy indices. The S&P 500 also dropped 1.8%, while the equal-weighted RSP ETF gained 5% in October. Investors are concerned about AI spending and slowing growth in core businesses. Nvidia, Apple, and other tech giants saw significant declines, with Nvidia losing its title as the world's most valuable company.
