<p>This thesis is an empirical analysis on momentum effects on the Swedish stock exchange’s sector indicesduring the period 2001 to 2009. The momentum effect is investigated by buying previous winner andshort selling previous losers with holding and formation periods over an intermediate time period (1-12month period). Our results are not coherent with previous studies conducted on the U.S market or theworld market, instead our results indicate that the Swedish stock exchange’s sector indices experience acontrarian effect over the intermediate time period. The results are adjusted for systematic risk and aresignificant on the 5%-level. Our result show that the weak form of the efficient market hypothesis isviolated and we therefore believe that a demand exists for easy and convenient investment vehicles withsector specific exposure, which could have a positive effect on the efficiency of the market.</p>

In particular, the examination will go through the most passive strategy, namely buy & hold, to a different degree of active indexing management such as sector and/or asset class rotations based on bottom-up, top-down and technical indicators. The analysis show that active strategies, if properly implemented, obtain risk-adjusted returns substantially higher than a passive approach, overcoming the issues of transaction costs and diversification which are typically claimed by a passive management. / O objectivo deste projecto é a comparação entre os prós e contras de gestão passiva e ativa através da realização de um estudo estatístico de várias estratégias através dos Exchange-Traded Funds. Em particular, a análise vai passar pela estratégia mais passiva, ou seja, buy and hold, para um grau diferente de active indexing management, tais como rotações do sector e / ou classe de ativos com base no bottom-up, top-down e indicadores técnicos. A análise mostra que as estratégias ativas, se forem devidamente aplicadas, conseguem obter retornos ajustados ao risco substancialmente superiores quando comparados com uma abordagem passiva, superando as questões de custos de transação e diversificação que normalmente são reivindicadas por uma gestão passiva.
