#风险回报比

Risk-return ratio (also known as risk-reward ratio) is a core indicator in investment decision-making, measuring the expected level of returns for investors when taking on specific risks. This concept emphasizes the dynamic balance between returns and risks, essentially helping investors determine whether it is worth taking on corresponding risks for potential returns through quantitative analysis. For example, when market sentiment improves, the risk-return ratio may decrease due to inflated asset prices, at which point it is necessary to adjust positions to avoid potential "pricing collapse points"; conversely, in structural corrections, high cost-performance assets often accompany a better risk-return ratio, becoming good opportunities for positioning. In practice, investors can evaluate the risk-return characteristics of products using tools such as the Sharpe ratio and maximum drawdown rate, or use the Kelly formula to calculate optimal positions, balancing win rates and odds with mathematical methods. It is worth noting that the risk-return ratio is not a static indicator and needs to be dynamically adjusted in conjunction with market conditions, personal risk preferences, and investment goals to achieve long-term wealth growth.
