Time to Transfer the Profits to Salmon Else? An emperical analysis of the stock market’s reaction to the announced resource rent tax on Norwegian aquaculture

On the 28thof September 2022, the Norwegian Government announced a proposal for resource rent taxation on the Norwegian fish farming industry. This thesis examines the Norwegian stock market's reactions to the proposal to raise awareness of its financial implications. These implications are answered using the event study methodology described byMacKinlay (1997). The sample consists of five salmon farming companies listed on the Oslo Stock Exchange, where all the companies are directly impacted by the implementation of resource rent tax. The primary objective is to identify if the resource rent tax announcement leads to a cumulative abnormal return significantly different from zero on the event day and in our main event window [-5, 5]. In addition, the thesis will investigate if there are signs of information leakage prior to the announcement and examine if there are any post-event price drifts. We will also attempt to determine how operational and financial flexibility affect the stock market's response. The analysis finds a cumulative abnormal return of -27.60% on the event day. The steep cliff shows that the market instantly changes the fish farming companies' valuation following receiving the information about the resource rent tax. In the main event window [-5, 5], we find a cumulative abnormal return of -44.03%. This cumulative abnormal return is distributed between the pre-event and post-event window. In the pre-event window [-5, -l], we find a cumulative abnormal return of -8.47%. Our findings could indicate information leakage prior to the event, but that would only be speculation. However, in the post-event window [ l , 5], we find a cumulative abnormal return of -7.96%, and we notice a price drift after the 28th of September 2022. All cumulative abnormal returns mentioned above are calculated using the market model and are significantly different from zero on all conventional levels. To measure operational flexibility, we have used harvested volume in Norway as a ratio of the total harvested volume. We identified a trend towards a higher concentration of harvested volume in Norway, resulting in a lower cumulative abnormal return. Further, to measure financial flexibility, we use a net debt to assets ratio. Also, here, we identified a trend towards a higher net debt to assets ratio resulting in a lower cumulative abnormal return. However, the results should be interpreted with caution due to the small sample size in our research.
