Buying and selling shares of companies, I work in a team of 10 and we manage roughly $10b (equivalent in USD).
Every day we will discuss new developments and how they affect our valuations for these businesses. These decisions are then factored into a portfolio model, which is then implemented by the dealer.
All in all, you have a lot of freedom, you aren't accountable for your time. I could be gone for the week and nobody would bat an eyelid, but the work is honestly so interesting you wouldn't squander your time like that.
