Design looks great and works really well.
A couple of points:
- I think it would be really helpful to users to see filtering options on the portfolio page, sort by profit, loss, investment etc. Especially if they have a large portfolio.
- The dark grey blocks and font aren't doing it for me. I feel like the colours could be improved and with a nice font the portfolio page would really ping.
But great work, I'll use this site for sure. Very useful.
