Listed companies across all equity markets are generally classified into three categories - large-caps, mid-caps, and small-caps. Large-caps are typically those companies that have larger revenues and profits, which get reflected in their large market-caps. They would typically be a part of several frontline indices of exchanges, on which, they are listed. The mid-caps and small-caps are typically smaller companies on these metrics and often act as a supplier to larger corporations. In some cases, these companies operate in a niche business and have limited competition. However, this aspect also restricts their market purview to a large extent.
