We address the issue of pricing multi-asset options in the context of asynchronous markets. Using the criterion that the carry P&L vanish we derive the expression of the correlation estimator for the asynchronous case. We study its historical behaviour for the case of the Stoxx50, S&P500, and Nikkei indices, then consider the special case of correlation swaps and compare our correlation to popular heuristic estimators. Finally we characterize practical situations whereby correlations larger than 1 are materialized as a P&L.
