Market Volatility Sours Americans' Moods in October

Americans' moods soured this month due to a volatile stock market.

The University of Michigan's consumer survey showed sentiment declined 6% in October.

The decline was driven by higher-income consumers and those with large stock holdings.

The S&P 500 index is down from its July peak, spooking investors.

Third-quarter earnings reports, especially from big tech, could move markets.
