I've been actively trading MAA for the past couple of months because it has become so predictable. As of late it seems to hit a wall of resistance when it approaches ~$45/share.

Then again, looking at all the apartment REITS, they all seem to have topped. Here's what I have noticed with the ones I actively follow: BRE can't seem to hit $30 anymore, AVB can't seem to clear $76, CPT can't go over $40 for more than a few moments, PPS can't stay consistently in the mid $17 range, and ESS struggles to get over $79-$80.
