摘要：

Under the assumption of options market makers' full delta hedging, the stock order flow captures private information in both the stock and options markets. Between 2001 and 2010, US stocks with newly listed options experience average increases of 16.8% in informed trading and 27.8% in uninformed trading in the following year compared to control stocks with similar propensities of listing. The disproportional increments reduce the overall probability of informed trading by 11.5% for the listing stocks. Dynamic analysis confirms that these structural breaks occur exactly around the option listing date. Information in the order flow is incorporated more quickly into the stock price after option listing. Finally, the option introduction benefits are positively correlated with the options trading volume.
