Everything You Need To Know About the CAPE Ratio

I just got back from 5 days backpacking and fishing in King’s Canyon (next to Sequoia) at a place called Rae Lakes.  It has been on my bucket list for years, and it did not disapoint.  Here is a quick photo before we dive into all things valuation related.  Lots and lots of (little) trout.

So, there has been a lot of discussion about the CAPE ratio on social media lately.  I’ve been writing on CAPE for a long time, including dozens of blog posts, a white paper, and a book – Global Value.  (I’ll even send you a free copy if you agree to write an honest review on Amazon, just email me.)  We launched an ETF on the findings at has been one of the top 5 launches of the year.  Barry did a nice post with links to a lot of writers thoughts on the topic.  I’ll add some of my findings with links below from the blog over the years.
