We discuss recent empirical and theoretical work showing that statistical properties of financial time series are rather complex under several ways. Specifically, they are complex with respect to their (i) temporal and (ii) ensemble properties. Moreover, the ensemble return properties show a behavior which is specific to the nature of the trading day reflecting if it is a normal or an extreme trading day.", "revisions": [ { "version": "v1", "updated": "2001-04-19T15:21:30.000Z" } ], "analyses": { "keywords": [ "financial markets", "financial time series", "complexity", "ensemble return properties", "extreme trading day" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable" } } }
