Do Firms Buy Their Stock at Bargain Prices? Evidence from Actual Stock Repurchase Disclosures

Using new monthly data we investigate open-market repurchase executions of US firms. We find that firms repurchase at prices which are significantly lower than average market prices. This price discount is negatively related to size and positively related to market-to-book ratio. Firms' repurchase activity is followed by a positive and significant abnormal return. Importantly, the market response occurs when firms disclose their actual repurchase data in earnings announcements, and this positive response is followed by a one month drift. Consistent with these results, we find that insider trading is positively related to actual repurchases
