Can Norwegian Mutual Fund Managers Pick Stocks?
Abstract
This thesis examines the performance and persistence of Norwegian mutual funds using
a comprehensive dataset (surviving and non-surviving funds) over the period 1983-2015.
We examine the performance of Norwegian mutual funds on aggregate level and individually,
using the Carhart (1997) four-factor model as our performance model. We find that
Norwegian mutual funds, on aggregate, do not produce significant abnormal risk-adjusted
returns. When examining mutual funds individually, we apply a cross-section bootstrap to
distinguish between skill and luck. The bootstrap is necessary for proper inference because
the cross-section of alphas has non-normalities in the tails of the distribution due to idiosyncratic
risk-taking and non-normalities in the individual fund’s alpha distribution. We
find no evidence of skills among the top performing funds. We do however find evidence
of bad skill among the poorest performers. There is no evidence of persistence among top
performers, but the performance of poor funds persists in short-term.
