Equity research

You spend a summer researching companies in one industry and then pitch an original investment idea to the people who run the money. This is a summer internship at Capital Group in London for MBA students, at the level the firm calls summer associate.

You do the work of an equity investment analyst, where equity means shares in companies. The summer builds to your recommendation on a company's shares, presented to portfolio managers and analysts, much as a full-time analyst would.
