Stock selection refers to the process of choosing which stocks or shares to invest in. It involves analyzing various factors such as financial statements, market trends, and company performance to determine whether a particular stock is likely to provide good returns for an investor. The goal of stock selection is to identify companies that are undervalued by the market but have the potential to grow significantly over time, resulting in high profits for shareholders. It requires careful research, analysis, and judgment on the part of the investor or fund manager to make informed decisions about which stocks to buy and hold.
