Include or not include, and where?

Getting my resume together this summer as I enter my final year of undergrad. I have the basics down as far as schooling and internships, but there are a few things I'm not sure to include. I want to go into S&T, particularly trading, and don't know if in my other skills/interests section is appropriate.

I was thinking about including two things, one is my personal account P&L. I have heard here that in an interview, banks may care about your own account with real money, even if it is small. NOT a fake account, but is this appropriate to put on a resume?

Also I own my own small business selling sporting goods. I want to express my entrepreneurial interests but is this appropriate for that section of the resume? Thanks in advance!
