We analyze the underlying markets with methods from large financial markets. More precisely, we show the existence of a strong asymptotic arbitrage (defined as in Kabanov and Kramkov [Finance Stoch. 2(2), 143-172 (1998)]) when the scaling factor converges to zero. We apply a result of Kabanov and Kramkov [Finance Stoch. 2(2), 143-172 (1998)] that characterizes the notion of strong asymptotic arbitrage in terms of the entire asymptotic separation of two sequences of probability measures. The main part of the paper consists of proving the entire separation and is based on a dichotomy result for sequences of Gaussian measures and the concept of relative entropy.","lang":"eng"}],"issue":"4","author":[{"first_name":"Fernando","id":"38874260","last_name":"Cordero","full_name":"Cordero, Fernando"},{"last_name":"Klein","full_name":"Klein, Irene","first_name":"Irene"},{"full_name":"Perez-Ostafe, Lavinia","last_name":"Perez-Ostafe","first_name":"Lavinia"}],"quality_controlled":"1","language":[{"iso":"eng"}],"type":"journal_article","publication_status":"published","user_id":"30615","date_created":"2019-02-04T12:33:28Z","department":[{"_id":"201230"}],"intvolume":" 5"}]
