The vol profiles for AVB are quite amazing. Long term value at 133 is likely to keep attracting price.
The POC at 161 has not built enough volume yet to escape the higher value YET. But it looks nice and wide and looks like it will. So I would say that the higher POC at 172 is not part of the leg down, which is why I'm making the symmetry projection down from the high at 189.
In any case, I think 133.28 is a fantastic place to look for long term buyers in AVB to step back in and push price higher. The proportions are all there and value looks to be developing nicely long term.
