What I like: you have huge exposure to different products within an asset class. If you are an equity trader, you may focus on only 1,2 products. But being an equity market risk manager, you and your team (3, 4 people) will have to oversee all products within equity: cash equity, program trading, margin loan, equity derivatives, exotics, etc. It's good knowledge for early career.
What I don't like: it's a monitoring role. Risk doesn't have that much a say in big decision making. And many times trader will do something over the limit and then ask risk for an exception - and we need to give them. Risk is not the profit generating department, and unfortunately, that means we are not the core.
