I'm sorry , but the stock was at 177 when Frank was still CEO in April. So it was while Frank's hands were still on the wheel when it dropped from 235 to 177.
The market dropped after someone finally had the ba--s to mention that Clover was not rainbows and kitty cats. That tells me that 235 was a lie because Frank didn't want anyone to be honest about the prospects of Clover. The market corrected after Frank's departure because now we have a leader that doesn't want to hide the dirty laundry.
The stock is up 10% since the market found out about Clover. It's not much, but it's better than the stock losing 25% of its value in the last 3 months of Frank's tenure.
Frank was a conman. It's clear to 90% of the employees. He destroys a company to boost the stock price, then he jumps ship. He did it with First Data, and he tried to do it with Fiserv. He was just a little too late jumping ship this time.
