摘要:
本研究采用事件研究法,调查美国证券交易委员会(SEC)将加密资产归类为证券的市场影响,聚焦被明确点名的加密资产,探索SEC干预如何影响资产回报与交易量。实证分析显示显著负面市场反应,公告后一周回报暴跌12%且持续一个月;市场反应的严重程度取决于情绪及资产特征(如市值、存续时间、波动率与流动性不足);还发现公告前存在显著的事前交易量效应,表明存在知情交易。
英文摘要:
This study employs an event study methodology to investigate the market impact of the U.S. Securities and Exchange Commission's (SEC) classification of crypto assets as securities. It explores how SEC interventions influence asset returns and trading volumes, focusing on explicitly named crypto assets. The empirical analysis highlights significant adverse market reactions, notably returns plummeting 12% over one week post-announcement, persisting for a month. We demonstrate that the severity of market reaction depends on sentiment and asset characteristics such as market size, age, volatility, and illiquidity. Further, we identify significant ex-ante trading volume effects indicative of pre-announcement informed trading.
