This paper analyses the share prices of the world's largest car manufacturers with a focus on the sensitivity to the price of lithium. Most car manufacturers display no relationship with the price of lithium except seven manufacturers, of which six are Chinese and exhibit strong positive lithium...

In this article, the Universal Approximation Theorem of Artificial Neural Networks (ANNs) is applied to the SABR stochastic volatility model in order to construct highly efficient representations. Initially, the SABR approximation of Hagan et al. [2002] is considered, then a more accurate...

We investigate the impact of the magnitude of current sales changes on asymmetric cost behavior. We expect that managers are likely to consider small (large) current sales decreases as temporary (permanent). Therefore, they will be less (more) likely to cut costs for small (large) current sales...

Cryptocurrencies are often thought to operate out of the reach of national regulation, but in fact their valuations, transaction volumes and user bases react substantially to news about regulatory actions. The impact depends on the specific regulatory category to which the news relates: events...

Whether high sentiment among investors is associated with lower risk aversion (Yu and Yuan [2011]) is not so clear. First, in regressions of returns on a proxy for variance, high sentiment comes with a relatively larger noise-to-signal ratio (lower power) and a bigger errors-in-the-regressor...

The most popular method of calculating asset prices is the capital asset pricing model (CAPM). What is the appropriate amount of years to use in the estimation and which variation of the capital asset pricing beta provides the best results? This research looks at the out of sample forecasting...

We show that the pre-FOMC announcement drift in equity returns occurs mostly in periods of high market uncertainty or risk premium. Specifically, this abnormal return is explained by a significant reduction in the risk premium (implied volatility and variance risk premium) prior to the...

Biomedical innovation in oncology has become riskier and more expensive, precipitating a withdrawal of private sector funding from the sector. In this article, we consider a portfolio-based approach to funding in which multiple distinct ovarian cancer treatment candidates are funded within a...

We investigate the option-implied investor preferences by comparing equilibrium option pricing models under jump-diffusion to option bounds extracted from discrete-time stochastic dominance (SD). We show that the bounds converge to two prices that define an interval comparable to the observed...

In this study, we separately estimate the implied volatility from bid prices and ask prices ofdeep out-of-the-money (OTM) put options on the S&P500 index. We find that the impliedvolatility of ask prices has stronger stock return predictability than that of bid prices. Our finding is robust to...
