About this series
`SP500_PE_TTM ÷ REAL_EPS_GROWTH_10Y`. The "real" PEG ratio that retail investing references invoke (CNBC, Investopedia, etc.) — uses TTM P/E, not CAPE's 10-year smoothed version like our companion CAPE_PEG tile.
Why it matters: Same intuition as PEG generally — "how many P/E points are you paying per percentage point of earnings growth?". Lower is better. The TTM version is more responsive to recent earnings inflections than the CAPE-based version, but also noisier — a 2009-style earnings collapse or a one-quarter blowout can warp it. Use both: TTM_PEG for the recent-cycle read, CAPE_PEG for the smoothed-cycle read.
How to read it: Like CAPE_PEG, no canonical level — read it relative to its own range. Sustained low readings (5-7) appear in regimes where the trailing P/E is reasonable AND growth is healthy; sustained high readings (15+) mark regimes where valuation has run ahead of growth. When TTM_PEG and CAPE_PEG diverge meaningfully, it's information: TTM_PEG below CAPE_PEG means recent earnings are running ahead of the 10-year average (cycle's hot); TTM_PEG above CAPE_PEG means the opposite (cycle's depressed).
Caveats: Same as CAPE_PEG — skips months where trailing 10-year real EPS growth is below 0.5%, leaving visible gaps in the Depression, post-WWII, and 2009 windows. Use those gaps as a "this metric is undefined here" signal rather than reading them as bullish/bearish.
