Blue-chip stocks represent the largest and most well-established companies in the market, typically with a long history of stable earnings, strong balance sheets, and a reputation for reliability. These companies often have a large market capitalization, which is the total value of all their outstanding shares, making them among the largest in the market. Additionally, blue-chip stocks tend to have high levels of liquidity, meaning there is significant trading activity, making it easy for investors to buy or sell shares without significantly affecting the stock price. Due to their size, stability, and liquidity, blue-chip stocks are considered safer investments compared to smaller or riskier companies.
