This thesis discusses whether price momentum returns differ in stable times compared to times when there is political uncertainty. First, this thesis investigates whether price momentum returns are still significantly positive. Furthermore, price momentum returns are compared over different years in Belgium, when there was no government active at that time period. The years 2008 up until 2011 are taken into account. I used t-tests to investigate whether the returns of the different years differ from each other. I found that price momentum positive returns still exist, but there is not enough evidence to state that price momentum returns differ significantly during times of uncertainty.
