Stock Value - I don't get it

Hey,

the following screenshot shows the post game graph of the stock market value. Please focus on the events around 50.

Megaman bought Redymare

Bassmaster bought Razzk

How can it be that megaman's stock value only grew half as much as bassmaster's although he bought the more valuable (in terms of stock value) company and on top was worth more before?
