Subject: YEY Failure Analysis
Has anyone done any research into what, specifically, caused YEY to flatten out a decade ago, then come roaring back in the 2020's? I've heard mention that inclusion of MLPs may have contributed to the first demise, but I assume they're still in the current stock selection universe.

If we can identify a measurable trend shift or critical metric epoch, then we could improve our returns by moving between YEY and the new ROE_Cash screen rather than staying fully invested in both through thick or thin times.
