The Fidelity Mega Cap Stock Fund primarily allocates at least 80% of its capital to the common stocks of companies characterized by substantial market capitalizations. For this fund, such firms possess market values comparable to those included in the Russell Top 200® Index or the S&P 100® Index. The portfolio has the flexibility to invest in both U.S. and international issuers, and it may pursue opportunities in either growth-oriented or value-focused companies, or a blend of both styles.
