An investment firm looked at 200 mergers between small companies and found that 128 of the new (merged) company’s stock price dropped immediately after the merger. They also determined that 19 of the companies whose stock rose in price had merger managers with experience from prior mergers.

|Stock Price Rises||19||53||72|
|Stock Price Falls||33||95||128|
