Large-cap securities, or those invested in companies with a market capitalization of more than $10 billion, provide stability in price, and often, steady dividend payouts that enhance the overall return on a portfolio. In the large-cap equities market, core mutual funds, which allow investors to gain exposure to specific market segments through a single investment position, are a popular choice. Core mutual funds with a focus on large-cap positions provide investors access to all aspects of the large-cap market, including growth- and value-tilted stocks. While investing in a large-cap core mutual fund provides some advantages, investors should be aware of the potential loss of principal and volatility inherent to equity holdings.

Among the top large-cap mutual funds to consider are the Columbia Large-Cap Enhanced Core Fund (NMIAX), the Fidelity Large-Cap Core Enhanced Index Fund (FLCEX), the Schwab Core Equity Fund (SWANX) and the BlackRock Advantage Large-Cap Core Fund (MALRX). The information presented here was current as of Oct. 13, 2018.

Fund managers focus on investment holdings in the U.S. market, with the majority of securities falling in the giant- and large-cap ranges.

Fund managers have the flexibility to invest in domestic and foreign issuers as they see fit, although the investment mix is focused within the United States.
