Ultimately, to answer to your question would require a lot more information. If it means anything though, I to have been looking at EWZ.
I hope I'm not too presumptuous, but I think there is a much bigger concern with what you currently have in your portfolio (portfolio generally indicates long term holdings), than what you want to add to it. Specifically, it appears that two thirds of the portfolio are in leveraged ETF's, and I have my concerns about QAI as well. Without getting into all of the gory details, holding leveraged ETF's are not generally ideal for the long term portfolio . . . They are instruments for short term "trading", not long term "investing". So be sure to learn all you can so that you use them effectively.
Don't get me wrong, I love the leveraged ETF's. But they have to be used properly to actually benefit from them. There are some good postings on this web site that explain the pitfalls of holding leveraged ETF's in a long term portfolio.
Once you fully understand what you already have, and the erosion that occurs as the market cycles up and down, then you can begin to consider other additions to your portfolio. The link below may begin to help you understand some of the consequences of using leveraged ETF's, as well as my concerns with QAI.
