Examining liquidity change surrounding 195 open market share repurchase announcements over the period 1998-1990, Wiggins (1994) finds only a small decline in bid-ask spreads and no significant change in depths following the announcement day. Similarly, Miller and McConnell (1995) and Kim (2005) find no clear evidence of a significant liquidity change as a result of open market share repurchases in the U.S. stock market.
