HCBK hasn't gone up through $7 recently because the company has been doing brilliantly.
It's mostly a case of a rising tide lifts all boats. The recent stress tests performed by the Fed, came out making poophills looking like roses, allowing JP Morgan & a lot of other banks to distribute a lot more in dividends & stock buybacks.
This lifted the whole banking index, lifting HCBK at the same time.
I don't see a reason why HCBK would be making more money. Mortgage rates are still pretty low. They need a lower cost of funds. Until rates start going back up, HCBK isn't going to be making a whole lot more money.
