EC's on common app

<p>I was wondering if I could put these on my EC's for the common app and if so how to word them. The summer between sophomore and junior year, I bought wholesale Zipnotes (cool post-it note invention) and sold them to businesses and made a little over a thousand dollars after all expenses and I do a lot of practice investing in stock simulators because I am working on a portfolio to use my own money.
A side question would these EC's be something that would help set me apart from other competition at schools like NYU Stern and Cornell?</p>

<p>Bump I need responses please</p>
