"And other forms of speculation"... Like buying the stock? You're not talking about reform - you can't remove speculation from the stock market without banning stock markets entirely. I agree that market manipulation (especially by those in power) is an enormous problem. Can we hope to truly fix that? Or are we just going for damage control by banning derivatives or the entire stock market?
