I recently caught on CNBC radio, comments by Jim Cramer regarding his dislike of trading Ultra Short ETF's and their negative tax effects to traders and their accounts. please share those comments or discussions or what you remmeber from those comments from his prior shows, if you have his text or printed articles, please share those too
He has compared the performance of the ultra short ETF's with that of the underlying securities and has proved they are not correlated, or at least not nearly as much as they should be. He basically says they are good for traders but useless for investors. I don't have a link for you but search www.thestreet.com as he's written multiple articles on this subject.
