Greetings! Tough day today. I have been trying to exploit a relative strength based approach to rank ETFs. DTO has been the top ranked ETF for a long time now. I have been making weekly posts on my blog: http://investics.wordpress.com/etf-performance/ Please do take a read, I would love to hear your comments and promise to reply to ALL comments ASAP. I look forward to make weekly posts regularly. Good Luck!! PS:- I am a retail investor, I have nothing to sell, just curious to exchange ideas.
