A few times a year, Slack Investor likes to take a snapshot of the markets using the Cyclically Adjusted Price to Earnings ratios (CAPE) which use ten-year average inflation-adjusted earnings. I first started using CAPE as a “value” tool in September 2021 and, my most recent look was in mid-November 2023. I have decided to do this CAPE market value analysis every 3 months – as I like to keep a feel of where we are – as the market cycles. The next update will be in mid-May 2024.
By plotting this CAPE over a period of time, we can look at how the whole sharemarket is currently valued in terms of historical data – this way we can track the whole share market as it oscillates between overvalued and undervalued.
Using monthly CAPE data from Barclays, the 40-yr mean is calculated and plotted together with the CAPE values. A “fair value” zone is created in green where the CAPE is within one standard deviation of the mean (average).
ASX 200 Value
FTSE 100 Value
S&P 500 Value
At the end of January 2023, the FTSE 100 (11% below the 40-yr average) is the only followed market “ON SALE”. I love a price reduction!
The ASX 100 (4% above the 40-yr average) is in the “Fair Value” zone. However, the S&P 500 still looks well overvalued at 32% above the 40-yr average – and has just moved above the “Fair Value” zone.
