Large cap companies are businesses with a market capitalization of $10 billion or more. These companies are typically well-established and have a stable financial history, making them less volatile than smaller firms. They often dominate their industries and are considered safer investments, attracting both individual and institutional investors. Examples of large cap companies include Apple, Microsoft, and Amazon. These firms usually have significant resources for research and development, marketing, and expansion. Their size allows them to benefit from economies of scale, which can lead to higher profit margins and consistent growth over time.
