Caligan Partners LP
 Caligan Partners LP Investment ManagersFinance Caligan Partners seeks to identify companies it believes are undervalued, potentially because their sectors are out of favor or may be undergoing significant transition and where the firm believes its influence can act as a catalyst for a re-valuation of the investment or help to change the underlying performance of the investment, whether through financial or operational restructuring or a strategic repositioning or transaction. Their focus on undervalued securities is due to its belief that purchase price is the most important determinant of the success of an investment. | Chief Executive Officer | 01/09/2017 |
