Small Caps Underperformed Large Caps Last Week



Market cap analysis

Large-cap stocks above $10 billion make up 87.3% of the Financial Select Sector SPDR Fund (XLF). These stocks have lost 4.7% YTD (year-to-date) and have lost 5.0% during the week ended December 11. In comparison, the broad-market S&P 500 ETF (SPY) lost 3.5% during the same period.

Smaller-capped stocks, those under $10 billion market capitalization, have underperformed large-cap stocks both year-to-date and last week. They have generated negative returns of 6.7% year-to-date and 6.4% last week. The underperformance of small caps relative to larger companies during the year hints at the vulnerability in the broader market. The sense is that investors choose to stay with large caps as they are safer bets amid uncertain global conditions.
