We present a new approach to identifying asset price bubbles based on options data. Given their forward-looking nature, options are ideal instruments with which to investigate market expectations about the future evolution of asset prices, which are key to understanding price bubbles. By...

While Over-The-Counter (OTC) markets have widely been studied for equity and interest-rate products, there is only scarce literature on OTC derivative equity markets. In this paper we use use Market Data for regular Eurex Options and OTC-Blocktrades to study differences for OTC and regular...

Are options on more volatile assets expected to provide higher or lower return? Using analytics, we show the ambiguous nature of the answer when the volatility differential is due to the systematic/priced risk. Here the difference in the expected return of the assets also matters and has an...

In this paper, we consider hedging and pricing of illiquid options on an untradable underlying asset, where an alternative instrument is used as a hedging instrument. We assume that the trade price of the hedging instrument is subject to market impacts caused by the hedger, as well as the...

I introduce and test a method to identify market expectations about value creation in mergers. Post-announcement market prices reflect beliefs about both merged and standalone firm values, and the likelihood of either outcome. Stock prices alone do not contain sufficient information to identify...

This paper documents a robust new finding that delta-hedged equity option return decreases monotonically with an increase in the idiosyncratic volatility of the underlying stock. This result can not be explained by standard risk factors. It is distinct from existing anomalies in the stock market...

We present a new finding that the return autocorrelation of underlying stock is an important determinant of expected equity option returns. Using an extended Black-Scholes model incorporating the presence of stock return autocorrelation, we show that expected returns of both call and put options...

Numerous studies find S-shaped pricing kernels, which is conflicting with standard theory. In contrast to that, based on a novel GARCH model with structural breaks, I show that the pricing kernel is consistently U-shaped. The results are robust to variations in the methodology and hold for...

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...

Contingent convertible bonds (CoCos) are increasingly popular financial instruments used by banks to satisfy capital requirements. CoCos with market-based conversion triggers in particular receive much attention in the literature. The pricing of CoCos with such a market trigger is problematic as...
