Depending on who you ask, large-cap stocks have a market capitalization above $5 billion, $8 billion, or $10 billion. Regardless of the cap cutoff you choose, large caps are definitely the biggest fish in the equities pond. When you think of most household names, chances are good that they're large caps. Apple Inc. (AAPL), Microsoft Corporation (MSFT), and The Coca-Cola Company (KO) are all considered large-cap stocks, to name a few.

Large-cap stocks are generally considered good bets for long-term investment strategies and hold many advantages. This is particularly true for buy-and-hold investors who are looking for stability that is often sweetened with a dose of dividend yield to balance the portfolio. Because of their size, large caps are less likely to succumb to economic pressures and conditions that can interrupt operations and drive down profits for smaller organizations.

If you're looking for some large-cap exposure for your IRA or another investment account in 2020 and beyond, exchange-traded funds (ETFs) offer a great alternative to choosing individual equities. ETFs are generally cheap to own and have high liquidity, making them suitable for any type of investor. In 2020, a number of factors are helping to fuel gains in technology and growth stocks, which make up a good portion of large-cap stocks. Catalysts include e-commerce, cloud computing, artificial intelligence, an improving economy, and the passing of U.S. tax reform. Speculators believe savings from tax reform could help tech and growth companies to invest tax savings on greater research and development.
