Small-cap stocks refer to stocks with a relatively small circulating capitalization. Generally, stocks with a circulating capitalization of less than 100 million are classified as small-cap stocks. The characteristics of small-cap stocks are that they have a relatively small market value, and most of them are stocks of small and medium-sized enterprises. They are easily influenced by market sentiment and have greater price fluctuations. Small-cap stocks often exhibit more active performance in the market and have more frequent trading, making them suitable for short-term investors.

The investment advantage of small-cap stocks lies in their small market capitalization, which is easy to be manipulated by the market, so higher investment returns can be obtained. In addition, small-cap stocks have greater growth potential because most of them are growth companies with high performance growth potential. However, small-cap stocks also have higher risks because their price fluctuations are greater and are easily influenced by market sentiment.

For investors, selecting small-cap stocks requires attention to factors such as the company's fundamentals, market prospects, and also requires a certain risk tolerance. When investing in small-cap stocks, investors should focus on controlling risks, reasonably allocate assets, and avoid blindly following the trend and excessive speculation.
