What does a commodities summer analyst in purchase do ?

In my time as a Commodities Summer Analyst, I worked with each of the desks (crude oil, nat gas, metals, power) on a project that would add value to their everyday functions, most of which included data analysis in Excel and broad research. I was also able to shadow the traders and salespeople to get a sense of what their daily routine was like and get weekly lessons on option theory, the industry, etc. from my manager.
