Mutual Fund Performance and the Market Timing Ability - Finnish Evidence

The purpose of this thesis is to examine the performance of Finnish equity funds and their market timing ability. Fund performance is evaluated by using annual returns and various risk-adjusted measures, including Sharpe ratio, DDSR, SKASR, Treynor ratio and Jensen’s alpha, whereas portfolio manager’s timing ability is examined with Treynor-Mazuy model and Henriksson-Merton model. The data is collected from the Finnish fund market during the sample period from January 1997 to February 2010. Results show that Finnish equity funds have been able to outperform the market return on a risk-adjusted basis, but these results are influenced heavily by the exceptionally good performance during the IT-bubble. Market timing models show that fund managers have been, to some degree, able to time the market but not a single fund have been able to possess security selection ability and market timing ability simultaneously.

Pohjoismaisten yhdistelmärahastojen menestyminen vuosina 1999–2012

Tämä Pro Gradu -tutkielma tarkastelee Pohjoismaisten yhdistelmärahastojen menestymistä vuosina 1999–2012. Tutkimuksen tavoitteena on tutkia rahastonhoitajien markkina-ajoituskykyä kolmella eri periodilla. Periodit koostuvat vuosista 1999–2005, 2006–2012 ja 1999–2012. Tutkimuksessa käytetään monia tunnettuja riskin huomioivia mittareita, kuten esimerkiksi Sharpen indeksiä ja Jensenin alfaa. Markkina-ajoituskykyä testataan Treynor-Mazuy ja Henriksson-Merton -malleilla. Tutkimus osoittaa, että vain harvoilla rahastonhoitajilla on markkina-ajoituskykyä. Tutkimuksesta ei myöskään löydetä viitteitä siitä, että tietyn-tyyppiset yhdistelmärahastot suoriutuisivat paremmin markkinoilla.

Tutkielmassa pyrittiin arvioimaan SRI-rahastojen riskikorjattua suorituskykyä tavallisiin rahastoihin verrattuna tavanomaisin mittarein. Lisäksi tutkittiin salkunhoitajan ajoituskykyä kummallakin rahastoryhmällä kahdella eri mallilla, Treynor-Mazuy mallilla ja Henriksson-Merton mallilla.

Performance of active portfolio management and the effect of stock market trend

Purpose of the study is to evaluate performance of active portfolio management and the effect of stock market trend on the performance. Theory of efficient markets states that market prices reflect all available information and that all investors share a common view of future price developments. This view gives little room for the success of active management, but the theory has been disputed – at least the level of efficiency. Behavioral finance has developed theories that identify irrational behavior patterns of investors. For example, investment decisions are not made independent of past market developments. These findings give reason to believe that also the performance of active portfolio management may depend on market developments. Performance of 16 Finnish equity funds is evaluated during the period of 2005 to 2011. In addition two sub periods are constructed, a bull market period and a bear market period. The sub periods are created by joining together the two bull market phases and the two bear market phases of the whole period. This allows for the comparison of the two different market states. Performance of the funds is measured with risk-adjusted performance by Modigliani and Modigliani (1997), abnormal return over the CAPM by Jensen (1968), and market timing by Henriksson and Merton (1981). The results suggested that in average the funds are not able to outperform the market portfolio. However, the underperformance was found to be lower than the management fees in average which suggests that portfolio managers are able to do successful investment decisions to some extent. The study revealed substantial dependence on the market trend for all of the measures. The risk-adjusted performance measure suggested that in bear markets active portfolio managers in average are able to beat the market portfolio but not in bull markets. Jensen´s alpha and the market timing model also showed striking differences between the two market states. The results of these two measures were, however, somewhat problematic and reliable conclusions about the performance could not be drawn.
