The paper proposes a novel direction to rationalize and quantify investors' flipping behavior and its effect on underpricing in IPOs through the use of a structural approach mode. The outcome is a proxy value that replicates investors' flipping behavior. When tested empirically, the model...

The implied volatilities provided by OptionMetrics in the IvyDB database suggest substantial deviations from put-call parity that do not really exist. In S&P 500 options, artificial deviations occur because OptionMetrics uses non-synchronous index and option prices and an average implied...

Stocks with high idiosyncratic volatility perform poorly relative to low idiosyncratic volatility stocks. We offer a novel explanation of this anomaly based on real options, which is consistent with earlier findings on idiosyncratic volatility (the positive contemporaneous relation between...

We analyze how informed investors trade in the options market ahead of corporate news when they receive private, but noisy, information about the timing and impact of these announcements on stock prices. We propose a framework that ranks options trading strategies (option type, maturity, and...

In recent years there has been a remarkable growth of volatility options. In particular, VIX options are among the most actively trading contracts at CBOE. These options exhibit upward sloping volatility skew and the shape of the skew is largely independent of the volatility level. To take into...

In this paper, we promote the approach of relative indifference pricing as a conceptual enhancement of real options theory whenever incompleteness comes into play. As until now the discussion of this concept is limited to the field of mathematical finance, our goal is to stimulate its diffusion...

Market option prices in last 20 years confirmed deviations from the Black and Scholes (BS) models assumptions, especially on the BS implied volatility. Implied binomial trees (IBT) models capture the variations of the implied volatility known as "volatility smile". They provide a discrete...

We examine the informed trading in the options market for firms announcing CEO turnover and their suppliers and find that pre-announcement options trading in both announcing firms and the suppliers have predictive power for abnormal returns around forced CEO turnover events. This effect is...
