"Mid-cap" refers to companies with a market capitalization typically between $2 billion and $10 billion. These companies are often seen as a balance between the growth potential of small-cap companies and the stability of large-cap companies. Investors may find mid-cap stocks appealing due to their potential for growth while still being relatively established in their industries. Mid-cap companies can be found in various sectors, including technology, healthcare, and consumer goods. They often have more resources than small-cap firms, allowing for expansion and innovation, but may still offer higher growth rates compared to larger, more mature companies. Investing in mid-cap stocks can provide diversification in an investment portfolio.
