Interesting action in COMMERCIAL R.E. shares

Long-time readers know I write about both fundamental and technical developments. One jumps out at me as potentially very important -- the action in the iShares Dow Jones U.S. Real Estate Index Fund, or IYR. This Exchange Traded Fund holds major commercial REITs -- apartment companies, office building owners, and the like.

Today, it's gapping below a long-term uptrend. This is the first sign of real technical weakness in this ETF in a long time. Hmm...
