Zero-Commission Trading: From Hero to Zero By Jeff Bacidore, Founder and President, The Bacidore Group LLC I was originally going to call this post “Ceci n’est pas une GameStop Post”, since it is a post inspired by GameStop but not really about GameStop. But after double-checking Wikipedia to make sure I was using this reference correctly (I wasn’t), I realized I should avoid trying to appear cultured and stick with references I am fairly certain I understand. With that said, I have no desire to discuss GameStop, as I don’t think I have much to add. (I may be selling myself short, but please don’t tell the Reddit guys! Haha.). But I came across an extremely timely paper on the broader effect zero commission trading has on markets. And given the current debate, I thought it might be useful to summarize some of the authors’ findings.
