Prof. David Ikenberry was the Chair of Finance at the University of Illinois at Urbana-Champaign and the Associate Dean of the Executive programs. Later he served as the Dean of the Leeds School of Business at the University of Colorado, Boulder, and now serves as the full professor in the School. He was an early pioneer among researchers examining long-horizon stock returns, particularly returns subsequent to major corporate news events. Much of his work relates to behavioral finance and the extent to which news is incorporated into market prices. His most noted work has studied open market stock repurchase programs.
