The Nasdaq Just Had Its Worst Day in 4 Months. Here's the Level That Would Signal a Correction, and What History Says Investors Can Do About It.

The Nasdaq fell 2.6% on October 22, its worst day in 4 months, driven by tech stock selloffs amid concerns about AI infrastructure spending payoff. The index would need to drop an additional 4.1% to enter correction territory. While corrections are occurring more frequently due to faster information dissemination and algorithmic trading, historical data shows recoveries are swift. Investors are advised to diversify portfolios across sectors and focus on quality companies rather than rotating out of growth stocks.
