Several important anomalies are stronger for more complex firms. Despite conglomerates being on average larger and more liquid than single-segment firms, anomalies are stronger for conglomerates. In the conglomerates-only sub-sample, anomalies are stronger for conglomerates with more...

This paper is an attempt to study fundamentally the valuation of insurance contracts. We start from the observation that insurance contracts are inherently linked to financial markets, be it via interest rates, or – as in hybrid products, equity-linked life insurance and variable annuities –...

We fully characterize the absence of Butterfly arbitrage in the SVI formula for implied total variance proposed by Gatheral in 2004. The main ingredient is an intermediary characterization of the necessary condition for no arbitrage obtained for any model by Fukasawa in 2012 that the inverse...

The Chicago Board Options Exchange (CBOE) Volatility Index (VIX) is considered by many market participants as a common measure of market risk and investors' sentiment, representing the market's expectation of the 30-day-ahead looking implied volatility obtained from real-time prices of options...

This paper examines how a target firm's trading volume, bid-ask spread, and stock return volatility respond over a two-week period to the announcement of M&A deals ("nonprice reactions"). I find that these variables are strongly correlated with changes in risk arbitrageurs' holdings surrounding...

To understand deviations from Covered Interest Parity (CIP) it is crucial to account for heterogeneity in funding costs---both across banks and currency areas. For most market participants, the no-arbitrage relation holds fairly well when implemented using marginal funding costs and risk-free...

Non-fundamental demand shocks have significant effects on asset prices, but observing these shocks is challenging. We use the exchange traded fund (ETF) primary market to study non-fundamental demand. Unique to the ETF market, specialized arbitrageurs called authorized participants correct...

We develop a framework for computing the total valuation adjustment (XVA) of a European claim accounting for funding costs, counterparty credit risk, and collateralization. Based on no-arbitrage arguments, we derive backward stochastic differential equations (BSDEs) associated with the...

We analyze a model of anomaly discovery and test its new predictions on both asset prices and arbitrageurs' trading. Consistent with existing evidence, the discovery of an anomaly reduces its magnitude and increases its correlation with other anomalies. Using 99 anomalies, we test the new...

Arbitrageurs with a short investment horizon gain from accelerating price discoveryby advertising their private information. However, advertising many assets mayoverload investors' attention, reducing the number of informed traders per assetand slowing price discovery. So arbitrageurs optimally...
