The Relative Signalling Power of Dutch-Auction and Fixed-Price Self-Tender Offers and Open-Market Share Repurchases

Abstract

We compare three forms of common stock repurchases. Dutch-auction self-tender offers and open-market share repurchase programs are weaker signals of stock undervaluation than fixed-price self-tender offers. The price increase from buyback announcements is greater when insider wealth is at risk, greater following negative net-of-market stock returns, and unrelated to prior market returns. Buyback announcement returns are also increasing in the fraction of shares sought, which is consistent with both signalling and an upward-sloping supply curve for stock.
