Subject: Re: OT: DEV ex US (IDEV ETF)
Ex-U.S. developed markets could be an interesting diversifier.

IMO (not worth much), it's not so much the current valuation level (e.g. current P/E, P/B) that's key, but how these levels are changing over some reasonable past stretch of time...

Looking at the valuation of individual firms makes good sense (rifle method). Some people also look at broader swaths of valuation (shotgun method).

If you're looking at ex-US markets in terms of top level valuation (The CAPE of the FTSE or Topix, etc) looking for good deals, two things to keep in mind:
(a) it's important to compare valuation levels to the historically average valuation levels of the same group, not to the US, and
(b) the group you're looking at has to be broad enough to be meaningful. A market dominated by 1-5 companies, or just 1-2 sectors, won't mean revert predictably to anything at all.

FWIW, here are some historically average CAPE values by sector for Europe and the US. Data up to 2013, I think it might have started 1973.
Top half tend to be more highly valued in the US, vice versa for the bottom half.

                Euro avg    US avg
Energy             15        18
Materials          15        19
Industrials        17        22
Healthcare         21        27

Telecom            20        18
Utilities          18        13
Financials         28        17
Tech               28        32
