Which role is best suited for me?

Hi guys, this is my first post so a bit of background detail. I'm starting university (undergrad) in October in the UK. I've been given an offer for straight economics at a supposedly target uni. I'm looking to get some work experience sessions over the summer but think it would really help if I had an idea of what sort of graduate position I would be applying for in a few years. I like the sound of trading, but not sure I would enjoy being sat infront of a computer the whole time. Have also heard stories of good traders just having a bad year but being fired none the less. I think I would like a bit more job security than that.

So, I want to be able to research different markets/companies, use knowledge of current events in these areas (political instability/level of development) and act on them. I want to be able to propose to invest and specialise in investing in different areas. Preferably I won't be doing the same thing everyday, but that's slightly secondary to me. I want to use my knowledge of global events and not get stuck in a bubble of short/long, sell/buy, this is very important to me. I want to be in a job that allows me to progress through a business, without being subjected to a slow death of powerpoint presentations and Excel spreadsheets. And I want to earn plenty of dollar.

This is all probably very unspecific, but if these ideas fit a particular job description please tell me. I'm not scared by how competitive it may be, I just want a tangible goal to aim for, as opposed to my current situation which is far too vague.

Many thanks.
