The Wisconsin 30 Index is an equal-weighted stock index that is updated annually on December 31.

The index was originally constructed to reflect the 30 largest Wisconsin stocks based on market capitalization as of 12/31/19. The index is rebalanced on an annual basis to reflect year-end market capitalizations. Returns prior to 12/31/19 are based on 12/31/19 constituents looking backward, with adjustments if a name did not exist in earlier periods.

The reports linked on this website were developed by students in the Lubar College of Business Investment Management Certificate Program under the supervision of faculty.*
