We examine the stock market valuation of large and systemic U.S. banks over the period 2003Q4-2014Q1. These are the banks included in a series of supervisory capital review and stress tests conducted annually since 2009 by the Federal Reserve. We extend Gordon's growth model of stock valuation,...

We find that exogenous structural shocks caused by terrorist attacks, wars, political turmoil and gold market specific events have a strong role to play in the analysis of dynamic relationships between gold and stock market returns. Our main finding is that the interaction between the gold...

Blockchain, based on the distributed ledger technology, provides immediate settlement of transactions of digital assets and direct ownership. Since settlement of transactions is immediate, the blockchain system requires an ultra short tenor interest rate curve that is always up-to-date. Today,...

We reveal a novel channel through which market participants' sentiment influences how they forecast stock returns: their optimism (pessimism) affects the weights they assign to fundamentals. Our analysis yields four main findings. First, if good (bad) “news” about dividends and interest...

In this paper, we derive a closed-form explicit model-free formula for the (Black-Scholes) implied volatility. The method is based on the novel use of the Dirac Delta function, corresponding delta families, and the change of variable technique. The formula is expressed through either a limit or...

An insidious form of market inefficiency, by which prices lose their informativeness and wealth is distributed arbitrarily, translates into V-shapes, that is sudden changes of the sign of the price drift. We use this insight to develop a new tool for the detection of reverting drift, the...

This paper uses machine learning tools to study the serial dependence (lead-lag relations) of commodity futures returns during the post financialization period (January 2004 – December 2019). We use LASSO (Least Absolute Shrinkage and Selection Operator) to select the predictors as the number...

In this paper we address three main objections of behavioral finance to the theory of rational finance, considered as “anomalies” the theory of rational finance cannot explain: (i) Predictability of asset returns; (ii) The Equity Premium; (iii) The Volatility Puzzle. We offer resolutions of...

We study the effect of a huge sports sentiment shock, unrelated to economic conditions or government actions, on stock market outcomes. After Brazil's 7-1 humiliating defeat to Germany in the 2014 World Cup, which is likely to be one of the largest sports sentiment shocks ever, the stock market...
