The leverage ratio is an important concept in the stock market. It reflects the relationship between stock prices and market conditions. When market conditions change, stocks with high leverage ratios will react quickly with large fluctuations in price, while stocks with low leverage ratios will react slowly with smaller fluctuations. Therefore, investors need to evaluate the leverage ratio of stocks when making investment decisions to better grasp the trend and risk of stock prices. Understanding the leverage ratio can help investors make more informed investment decisions and improve investment returns.
