To this end, we construct a sectorial strategy, taking as a market risk factor the sectorial index to which the securities belong. From our results, we conclude that the aforementioned strategy is of limited use, given that no extraordinary consistent yields are obtained. From this, we conclude that the hypothesis of the efficient market can be accepted.2015http://zaguan.unizar.es/record/15080610.1080/13504851.2015.1042137http://zaguan.unizar.es/record/150806oai:zaguan.unizar.es:150806APPLIED ECONOMICS LETTERS 22, 18 (2015), 1511-1514All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/closedAccess
