Short selling, and its informational role in the formation of stock prices have been the epicenter of prior literature. Is there a relationship between short selling and abnormal returns? While numerous studies found a negative relationship, researchers do not unanimously agree on the existence, nor the strength, of this relationship. Using net short positions extracted from the registry of the FI for stocks listed in the OMX Stockholm 30 Exchange from January 2017 to December 2020, we examine this relationship exclusively in Sweden. The results have been scrutinized via regression analysis to verify if there is any significant relationship between the announcements of total net short positions and the non-adjusted, as well as the risk-adjusted abnormal returns. We did not find enough evidence to validate previous studies that supported the notion that heavily shorted stocks generate negative abnormal returns for the long buyers. There was a perceptible increase in both risk-adjusted and non-adjusted abnormal returns within a three-day window after the announcement of a short position. Yet, the value was merely zero, inferring that a higher level of short interest does not lead to negative stock returns.
