英文摘要:
Prospect theory is widely viewed as the best available descriptive model of how people evaluate risk in experimental settings. According to prospect theory, people are risk-averse with respect to gains and risk-seeking with respect to losses, a phenomenon called \"loss aversion\". Despite of the fact that prospect theory has been well developed in behavioral economics at the theoretical level, there exist very few large-scale empirical studies and most of them have been undertaken with micro-panel data. Here we analyze over 28.5 million trades made by 81.3 thousand traders of an online financial trading community over 28 months, aiming to explore the large-scale empirical aspect of prospect theory. By analyzing and comparing the behavior of winning and losing trades and traders, we find clear evidence of the loss aversion phenomenon, an essence in prospect theory. This work hence demonstrates an unprecedented large-scale empirical evidence of prospect theory, which has immediate implication in financial trading, e.g., developing new trading strategies by minimizing the effect of loss aversion. Moreover, we introduce three risk-adjusted metrics inspired by prospect theory to differentiate winning and losing traders based on their historical trading behavior. This offers us potential opportunities to augment online social trading, where traders are allowed to watch and follow the trading activities of others, by predicting potential winners statistically based on their historical trading behavior rather than their trading performance at any given point in time.

中文摘要:
前景理论被广泛认为是人们在实验环境中评估风险的最佳描述模型。根据前景理论,人们对收益厌恶风险,对损失寻求风险,这种现象被称为“损失厌恶”。尽管前景理论在行为经济学的理论层面上得到了很好的发展,但大规模的实证研究很少,而且大多数都是用微观面板数据进行的。在这里,我们分析了一个在线金融交易社区的8.13万名交易员在28个月内进行的2850万笔交易,旨在探索前景理论的大规模实证方面。通过分析和比较盈亏交易和交易者的行为,我们找到了损失厌恶现象的明确证据,这是前景理论的本质。因此,这项工作展示了一个前所未有的前景理论的大规模实证证据,它对金融交易有直接的影响,例如,通过最小化损失厌恶的影响来开发新的交易策略。此外,我们还引入了三个受前景理论启发的风险调整指标,以根据历史交易行为区分胜负交易者。这为我们提供了扩大在线社交交易的潜在机会,在这种交易中,交易者可以根据其历史交易行为,而不是任何给定时间点的交易表现,通过统计预测潜在的赢家,从而观察和跟踪他人的交易活动。
