Seems like you want a great browser app and stock analysis apps. What are you currently using for browser? Maybe brokerage firms offer apps? Otherwise what stock analysis app do you need to work well on phone? Anways, I was really thinking about hardware.. For me I want approx 6" screen, excellent camera, 2 day battery life with typical usage, high performance chip. 4 to 6 GB ram and 128GB memory on board with expandable memory. Good sound/speakers. Other stuff is nice but not essential like finger print scanner. .
