I have this link, but I always thought that it was not reliable:

As per your link, I would like to understand why the P/E of the Russel 2000 is so high…

The multpl.com P/E is actually an adjusted the P/E. It basically adjusts for cyclicality - it also is an argument that the market is not as cheap as many people say.
