Abstract We derive the limit of infill asymptotic distribution for the sum of positive returns of prices or log-prices in a given period of time. The framework is multivariate and quite general: it allows for the presence of leverage effects and jumps with finite activity. In a second step, the results are used to estimate the drifts (or rather, the Sharpe ratios) of the continuous part of the processes.

Joint work with Nour Meddahi

All interested people are warmly invited to take part Best regards in the meantime, Cecilia
