Credit default swaps (CDS) are similar to out-of-the-money put options in that both offer a low cost and effective protection against downside risk. This study investigates whether put option-implied volatility is an important determinant of CDS pricing. Using a large sample of firms with both...

This article empirically analyzes some properties shared by all one-dimensional diffusion option models. Using Samp;P 500 options, we find that when sampled intraday (or inter-day), (i) call (put) prices often go down (up) even as the underlying price goes up, and (ii) call and put prices often...

Recent empirical studies find that once an option pricing model has incorporated stochastic volatility, allowing interest rates to be stochastic does not improve pricing or hedging any further while adding random jumps to the modeling framework only helps the pricing of extremely short-term...

This paper addresses several questions about Chapter 11 stocks regarding their trading environment, fundamental value, and performance. First, we show that there exists active trading for Chapter 11 stocks throughout the duration of the bankruptcy process. Second, applying option theory to the...

We test the hypothesis that insider trading impairs market liquidity, by analyzing intraday trades and quotes around 1,497 IPO lockup expirations in the period 1995-1999. We find that, while lockup expirations are associated with considerable insider trading for some IPO firms, they have little...

This paper examines the information embedded in both the stock and option markets prior to takeover announcements. During normal periods, buyer-seller initiated stock volume imbalances are significant predictors of next-day stock returns and option volume imbalances are uninformative. However,...

We study the dynamic relation between aggregate mutual fund flow and market-wide volatility. Using daily flow data and a VAR approach, we find that market volatility is negatively related to concurrent and lagged flow. A structural VAR impulse response analysis suggests that shock in flow has a...

This paper studies Nasdaq market makers' activities during the one-and-half hour pre-opening period. Price discovery during the pre-opening is conducted via price signaling as opposed to the auction used to open the NYSE or the continuous market used during trading. In the absence of trades,...
