Commonality in equity options liquidity: Evidence from European Markets

Research output: Contribution to journalArticle

Electronic versions



This paper examines commonality in liquidity for individual equity
options trading in European markets. We use high-frequency data to
construct a novel index of liquidity commonality. The approach is able
to explain a substantial proportion of the liquidity variation across
individual options. The explanatory power of the common liquidity
factor is more pronounced during periods of higher market-wide
implied volatility. The common factor’s impact on individual options’
liquidity depends on options’ idiosyncratic characteristics. There is
some evidence of systematic liquidity spillover effects across these
European exchanges.
