摘要

我们分析了 2008 年卖空禁令期间期权和 CDS 市场的价格发现。在被禁股票中，那些未平仓认沽认购比率高、合成股票价格比率低或 CDS 比率高的股票在随后几天表现不佳。此外，在禁售期间，未被禁售股票的期权价格更有效。这些研究结果表明，知情投资者会在市场高度低迷的情况下参与衍生品交易，而且衍生品价格包含了更多关于禁售期间股票价格的信息。

Trading options and CDS on stocks under the short sale ban

We analyze price discovery in the options and CDS markets during the 2008 short-sale ban. Among the banned stocks, those with high open-purchased put–call ratios, low synthetic-to-stock price ratios, or high CDS rates exhibit poor performance in the following days. Additionally, options prices are more efficient for unbanned stocks during the ban period. These findings suggest that informed investors engage in derivative trading during highly distressed market conditions and that derivative prices contain more information about stock prices during the ban.
