Worth including on my resume?

Hello,

I have a question on whether or not I should include these two items on my resume when applying for jobs or if they should just be brought up in interviews. I am in my fourth year of undergrad at a reasonably strong Canadian school and I am looking for an AM or HF research position once done in May, I am also taking the CFA level 1 test in June. Last summer I was fortunate enough to have been offered a great opportunity at a fantastic buyside firm and I am also one of the managers for the school trust fund. My question is whether or not it would be worthwhile to include the two portfolios I manage and the articles I have started writing for Seeking Alpha or if that would just be clutter? I have been trying to keep my resume to just one page which if I included these items I would most certainly have to remove other items including a case competition. I would appreciate opinions on if that would be too much or too focused for a resume?

Thanks
