Investing in small-cap stocks can be a great way to diversify your portfolio and potentially earn higher returns. Small-cap companies are those with a market capitalization between $300 million and $2 billion, and they often have higher growth potential than larger companies due to their ability to innovate and adapt more quickly to changing market conditions. Higher returns are one of the main advantages of investing in small-cap stocks. Investors can diversify their portfolios and lower risk by making investments in small-cap stocks. Small-cap companies sometimes operate in specialized industries or have ground-breaking goods, which can protect them from general market downturns.
