Wrt to CAPE:
1. The data to me appears to indicate a change in relationship since 1988 and a tendency towards higher valuations.
2. Interest rates alone cannot account for this as other low interest rate periods did not accompany valuation increases like this e.g 3 month treasury bills were below 0.5% from 1942-1946.
3. The main contender I can see is the Fed or central bank put, which started with Greenspan after the 1987 stockmarket crash:
An unkind interpretation is that the central bankers are a bunch of serial bubble blowers (whatever a bubble is). A less severe interpretation is that they save the system from systemic risk and this has the side-effect of possibly increasing accepted valuations over time.
In terms of value investors relying on CAPE, central banks may have not only taken away their lunch (deprived them of low CAPE periods) but also given them a massive prolonged wedgie (in terms of higher CAPEs for longer than they imagined possible).
Valuations matter, but I'm very sceptical of the CAPE valuation narrative.
