Investing in Large-cap stocks can be a great way to diversify a portfolio and benefit from the stability that larger companies often offer. Large-cap stocks are typically those with a market capitalization of over $10 billion, and they can represent some of the most recognizable names in the stock market. Investing in these larger companies can provide a certain level of security due to their size and can help guard against the volatility that smaller companies often expose investors to. Large-cap stocks are also often associated with more reliable dividends and more stable earnings over time.
