Some visual feedback. I don't know if it's just me but the mission text "The easiest way to ask..." is blurry. I'd consider changing the shadowing/background color/font.
The front page could have some more sample data to help the user understand what they are getting into. Maybe a recent gainers/losers of stocks that are defined as "value". Or, since there is a good amount of research/literature/blogs that focus solely on value investing, it might be useful to add these as a supplement to the statistics you are planning on showing. I feel like people want to have as much information at there disposal when making investment decisions, and the mockups seem a little sparse to me as an individual investor.
I'm Azuldophin's partner, on a throwaway acct. Everyone's advice has been a great help so far. One thing to add, how would you compare certain neighborhoods in SF to ones in NYC? It would be great to have some context that we could relate to. For example, it sounds like the Mission roughly equals a more grungy Williamsburg.
