Small companies
Small-cap companies are modest sized ($2 billion or less in market capitalization) and often young firms that bring new products and services to market—though some are mature and stable businesses. They operate in niche markets or relatively new industries with long-term growth potential. Investors tend to incorporate small caps into their portfolios because they don’t move directly in lockstep with the broader market, providing diversification.
