BRAND STACKING!!!1!11! (angry fist)

[Brother22]

I have been noticing a pattern with my highest ROI keywords. The company I work for sells a ton of different brands. Over the last month one by one my ranks are droping down by about three to the parent companys brand stack. Now I know that Google favors brands but it seems in the last month they have become much more aggressive with brand stacking. Has anyone else noticed this problem or has there been some action on the part of Google to make this happen?

lol.... Brand Stacking... I have not heard that term used before.  Thanks.

In my SERPs I am seeing Wikipedia and .gov stacking.
