講題: The Informational Role of Index Option Trading
Do order flows in index derivatives play an informational role? Net buying pressure in index put options traded on the International Securities Exchange (ISE) positively and robustly predicts S&P 500 index returns. This result obtains symmetrically for net put buying and selling, indicating that it is not due to hedging via put buying. Instead, our finding accords with the notion that market makers have private information and set quotes to attract orders from outside investors. Supporting this notion, we find that the predictive ability of put order flow is higher when the differential between bid-to-bid and ask-to-ask returns is higher.
