There's speculation Twitter is finally focusing on co-founder Jack Dorsey as the permanent CEO, and big changes to the company's board could be announced as soon as Thursday.
Even though the stock is down 27 percent since Dorsey took over as interim CEO on July 1, SunTrust managing director Robert Peck believes Dorsey is the best fit for the top post and can successfully grow the user base.
"Internally, we think he has the executive support. We also think that for the employees he's [a] rallying point, they rally around him. Externally, we finally saw publicly shareholders come out and support Jack," Peck said Wednesday on CNBC's "Fast Money."
