摘要：
本文研究提供了支持金融市场中新定义有效性的实证证据。作者开发了一种确定投资者风险态度的新方法。分析了1889-1978年美国金融市场投资者的风险态度，结果显示1977年投资标普500指数的权益投资者表现出风险厌恶，而投资美国国债的无风险资产投资者则表现出不足的风险寻求行为，可视为一种风险厌恶行为。这些发现表明，金融市场中的新定义准确反映了投资者行为，应在投资策略中加以考虑。
英文摘要：
This study presents empirical evidence to support the validity of new definitions in financial markets. The author develops a new method to determine investors' risk attitudes in financial markets. The risk attitudes of investors in US financial markets from 1889-1978 are analyzed and the results indicate that equity investors who invested in the composite S&P 500 index were risk-averse in 1977. Conversely, risk-free asset investors who invested in US Treasury bills were found to exhibit not enough risk-loving behavior, which can be considered a type of risk-averse behavior. These findings suggest that the new definitions in financial markets accurately reflect the behavior of investors and should be considered in investment strategies.
