<prompt> Human: Reading about the Etsy IPO a few days ago and how it shot up so quickly got me thinking about this; if I simply invested a few thousand dollars in Etsy right as it opened and used some automated trading software to ensure I would sell when the price started slipping, what kind of risk would I be taking? I realize the price might not go up at all, but by picking a very public and well advertised IPO I feel like that risk could be mitigated, and other than that I cant see why I shouldnt do this. Ive never invested in stocks before and have only a basic understanding of how it works, but if Im understanding this right I dont know why everybody wouldnt do this... am I missing something?  <response>: Ive never invested in stocks before and have only a basic understanding of how it works,Yes. We know.
