Diversifying into Real Estate

[hlacheen]

My portfolio is currently made up of domestic/international equities. I want to diversify a bit into real estate. I'm thinking about putting 10% or so of my portfolio into SPDR DJ Wilshire International Real Estate ETF (RWX)

Here is some info about the ETF: https://www.ssgafunds.com/etf/fund/etf_detail_RWX.jsp
Here is a video interview with the guy who runs it I believe: http://publish.vx.roo.com/thestreet/port...amp;bitrate=300

The expense ratio is around 0.60% Its allocation is about 20% Australia, 19% Japan, 17% U.K., and I think 15 other countries make up 7% or less each.

Do you think will be a good addition to my portfolio? I have a very long horizon. Also, I'm just pulling 10% out of my ass... I don't know how one would figure out the proper percentage for this.

Thanks for the help.
