This study aims to search the existence of calendar effects (also known as calendar anomalies) in the Portuguese Mutual Funds Market. Since mutual funds can contain other securities besides stocks, it becomes relevant to study this market, filling a lack found in the literature for the Portuguese markets. Additionally, calendar patterns can be helpful for consultants and managers, potentiating their performance; and also for individual investors since they can try to exploit these anomalies. Our study analyses a sample of the daily shares’ values of the Portuguese mutual funds from 2002 until 2012 and the effects studied are the following: Turn of Year Effect; Turn of Month Effect; Weekday Effect; Holiday Effect; September Effect. We have found some evidence for the Turn of Year Effect and strong evidence for the existence of a Turn of Month Effect. Likewise, there is some evidence that the Holiday effect is also present. Our findings reveal that this market has some lack of efficiency, since these effects could have, in fact, been predicted and they could have given a return of 6% (Turn of Year) or even 26% (Turn of Month). Keywords: Calendar effects; anomalies; Portuguese mutual funds; seasonality. iii INDEX ABSTRACT ................................................................................................................................ iii 1.

INTRODUCTION Since the work of Fama (1970) about the Efficient Market Hypothesis, the debate over this issue has been developing exponentially, given place to the birth of a new paradigm (or even subject) in that field, the Behavioural Finance. The latter, apart from the paradigm previously established, defends that economic agents are not fully rational and that there are limits to arbitrage and thus markets will not be efficient. If this is true, then there will be a mispricing and the actual returns will not be the same as the expected returns, this is, there will be abnormal returns (either negative or positive). Given that, an anomaly is referred as a persistent and well known mispricing, as defined by Singal (2004). Hence, each calendar anomaly is also a persistent and well known mispricing, because returns seem to be correlated with some specific periods of the calendar and not only with economic and financial variables. Knowing this, a lot of studies have been carried during the last decades and they had found empirical evidence of this type of anomalies, however the majority of the studies is applied
