How to Survive Extreme Market Volatility for the Rest of October

After the S&P 500 and Nasdaq Composite hit fresh record highs on Oct. 6, the tone on Wall Street shifted sharply within days. The Oct. 12–16 week was especially harsh for technology investors as renewed inflation concerns, elevated AI valuations, and pressure on semiconductor stocks drove a sell-off. By Oct. 16, the Nasdaq posted its worst weekly performance since June, falling 572.99 points, or 2.1%, to 26,140.03 on Friday. For the week, the Nasdaq lost 4.5% and the S&P 500 fell 1.9%, both their worst since June; the Dow gained 0.7%. The article links the volatility to past shocks like 1929 and Black Monday.
