What is Portfolio manager, sub-portfolio manager, pod analyst?

A portfolio manager is the person who decides the positions of a portfolio within the limits of an owner of the capital and answers for its result. On a platform, a sub-portfolio manager runs a slice of a portfolio manager’s capital with its own limits and a share of its own profit, inside the manager’s team. A pod analyst works for a portfolio manager on research, data and position monitoring, without capital of their own.
