An equity research analyst is generally a step up from an equity research associate. While you may still be working under a more senior equity research analyst, you may not be doing the more grueling research tasks such as financial modeling; you may have research associates for that. At this point in your career, you might also be expected to start specializing in a small group of firms.
What is very important to recruiters at this stage is how accurate your forecasts and reports have been. These allow fund managers to make financially beneficial decisions in the market. This resume does a good job of quantifying that accuracy and the subsequent financial gain of their previous employers.
