The market implied volatilities for target stocks during the period between an acquisition announcement and the transaction resolution were examined for differences between samples of successful and failed transactions. By constructing volatility ratios for all cash and pure stock swap transactions, I find that market implied volatilities for successful and failed transactions diverge over time for cash bids but not stock bids.
