Abstract
The Husson Stock Index (HSI), developed by Marie Kenney under the supervision of Associate Professor J. Douglas Wellington, aims to track the performance of the Maine Economy through the tracking of various publicly traded companies. These companies are either Maine-based or contribute significantly to the economy in Maine through revenue or employment. Since its introduction, numerous companies have been removed from the index, bringing the total down to 23. Additionally, there has not been a major statistical review of the tracking efforts of the index since its creation. This study aims to identify new companies to be added to the index, create a new weighting system that more accurately represents each company’s contribution to the state, and conduct a statistical review of past performance in relation to the Maine economy. The addition of four new companies and the reformatting of the index proves to be necessary to further the development of the index. The statistical review has shown that the HSI and other relevant large stock indexes are ineffective in tracking the real GDP growth of the Maine economy. Beyond laying the groundwork for future additions of companies and new weighting methods, we also seek to open a new path towards the creation of a tracker for the real GDP growth of the State.
