The biggest loser in all this is passive management and closet indexers. There's so much dispersion in the market now, which is healthy. In a good case, this happens over a long period, indexes rebalance, and new leaders emerge. In a bad case, you'd see a crash in the indexes. I'm watching implied correlation to make sure it's not a crash scenario; it's currently at 10, which means a massively rotational market, great for active management.
There were crazy program trades smashing down large cap index names and then slowly finding their way to other parts of the market. You can see it in real time getting reallocated.
