Despite abundant empirical evidence of informed trading ahead of major corporate events, no such evidence has been reported in the case of corporate spinoff (SP) announcements. This is surprising, as SP announcements are unexpected, and are also associated with a positive price jump in the parent company’s stock. Using a sample of 280 US announcement events from 1996 to 2013, we document significant pre-announcement informed trading activity in options for about 9 to 16% of events in our sample. In contrast, we find statistically insignificant evidence of informed trading in stocks, suggesting that informed traders employ leverage through options. In …
Option Listing And Information Asymmetry, Jianfeng Hu
Option Listing And Information Asymmetry, Jianfeng Hu
Research Collection Lee Kong Chian School Of Business
Option listing increases informed and uninformed trading by 12.4% and 23.9%, respectively, in the US between 2001 and 2010, hence reducing relative information risk. We establish the causal effects using control stocks with similar propensities of listing and a quasi-natural experiment using option listing standards. The benefits are more prominent for stocks with active options trading and opaque stocks. The reduction of information risk is larger for good news than bad news, and the stock price response to earnings surprise weakens after listing. The results suggest that options improve the overall market information environment beyond substitutional effects to stock trading.

This study examines the relationship between company management guidance, and ex-ante crash risk over the duration of 2008(Jan 2006-Dec 2009) financial crisis using the implied volatility skew, which is based upon ex-ante volatility implied by the pricing model developed by Black-Scholes (1973). The study finds that over the duration of this crisis period, management guidance decreases with a rise in ex-ante crash risk. Further, the study provides evidence on the relationship of management guidance and earnings volatility, and how that is affected by a firm's industry product concentration based on the Herfindahl-Hirschman Index (HHI) score.

Using a sample of cash tender offers occurring between 1993 and 2002, we find evidence that the options market has become the preferred venue for traders attempting to profit on anticipated announcements. Options offer advantages relative to stocks. Traders gain leverage by trading in options and multiple options contracts on an individual stock. The results of our study indicate that a substitution effect does exist. Abnormal volume in the option market replaces abnormal volume in the stock market prior to cash tender offer announcements, and this abnormal option volume precedes abnormal stock volume for targets with or without traded options.
