Jumps or staleness?
A Kolokolov, R Renò - Journal of Business & Economic Statistics, 2024 - Taylor & Francis
Even moderate amounts of zero returns in financial data, associated with stale prices, are
heavily detrimental for reliable jump inference. We harness staleness-robust estimators to …

Powers Correlation Analysis of Returns with a Non-stationary Zero-Process
The higher order dynamics of individual stocks is investigated. We show that classical
powers correlation analysis can lead to a spurious assessment of the volatility persistence or …
