Stock market tail risk, tail risk premia, and return predictability
Journal of Futures Markets, 2021AbstractIn this study, we use the S&P 500 options prices to derive various tail risk indexes. We then decompose the option‐implied tail risk indexes into the conditional tail risk of stock returns and equity tail risk premia. We examine the predictive power of the conditional tail risks and equity tail risk premia for various stock portfolio ...

We show that the beta with respect to an index of global ex ante tail risk concerns (𝔾ℝ𝕀𝕏), which we construct using out-of-the-money options on multiple global assets, negatively drives cross-sectional return variations across asset classes, including international equity indices, foreign currencies, and government bond futures.

Journal of Economic Behavior & Organization, 2020
We study changes in expectations by incorporating tail risk in a Bayesian learning framework with information frictions. Using a signal extraction problem, we find that economic agents behave differently in the face of tail risk. First, under tail risk, uncertainty shocks lead to a decrease in expectations, which implies more pessimistic forecasts.

SSRN Electronic Journal, 2004
This paper discusses the notion of tail risk, and the ability of a tail risk measure to reflect this kind of risk. In particular, Yamai and Yoshiba's (2001, 2002) notion of strict risk measure tail risk is discussed and linked with a different notion of tail risk, the pK-tail risk, which is the risk associated with the probability measure conditional ...

A Theory for Measures of Tail Risk
Mathematics of Operations Research, 2016The notion of “tail risk” has been a crucial consideration in modern risk management and financial regulation, as very well documented in the recent regulatory documents. To achieve a comprehensive understanding of the tail risk, we carry out an axiomatic study for risk measures that quantify the tail risk, that is, the behaviour of a risk beyond a ...

Oil tail risk and the tail risk of the US Dollar exchange rates
Energy Economics, 2022This study tests both the in-sample and out-of-sample predictive value of oil tail risk for the tail risk of US Dollar exchange rates (USD/CAD, USD/GBP and USD/JPY), where the conditional autoregressive value at risk (CAViaR) of the Engle and Manganelli (2004) is used to estimate the tail risks under 1% and 5% VaRs.

We examine the pricing of tail risk for 43,000 stocks from 46 countries between 1995 and 2013. We decompose tail risks into those with respect to local and global market returns and find that both risks are independently priced. Due to the increased demand for hedging tail risks, the premia for both tail risks are positively related to globalization ...

The Journal of Investing, 2014
For purposes of risk management, typically used returns distributions are asymptotic to zero, the most popular being the Gaussian and Power Functions. Yet, this asymptotic property of tail risk is relatively unexploited in thinking about the most vexing of managerial behaviors, the tendency to ignore the most threatening hazards facing the organization.
