Core CPI (Excluding Food & Energy) vs S&P 500 Price-to-Earnings Ratio (Forward)

How These Two Indicators Relate

Core CPI sits in the inflation category and S&P 500 P/E sits in the growth category, so they describe different parts of the same economy. Watching them together provides cross-checks: a coordinated move in both directions confirms a regime shift, while a divergence often reveals which sector of the economy is leading or lagging.

The two indicators are currently moving in opposite directions. Core CPI has moved higher +0.3% from the prior reading, while S&P 500 P/E has moved lower -1.20. Divergent moves on related indicators usually flag a regime shift in progress — one of the two is leading and the other is lagging.

What Core CPI (Excluding Food & Energy) Measures

Core CPI measures consumer price changes excluding food and energy, which are volatile and often driven by supply factors rather than monetary policy. It is the Fed's preferred gauge of underlying inflation trends.

Core CPI at 3.1% shows that underlying inflation remains sticky above the Fed's 2% target. Housing costs and services inflation are the primary culprits. For executives, sticky core inflation means the Fed is unlikely to cut interest rates soon, keeping borrowing costs elevated. Budget planners should assume inflation-adjusted cost increases of 3%+ for services, labor, and real estate.

Methodology: Core CPI uses the same methodology as headline CPI but excludes the food and energy components of the basket. This removes about 22% of the index weight. Shelter costs (rent and owners' equivalent rent) are the largest component of core CPI at roughly 44% of the core basket. Source: U.S. Bureau of Labor Statistics (series CPILFESL).

What S&P 500 Price-to-Earnings Ratio (Forward) Measures

The forward price-to-earnings ratio measures the S&P 500 index price relative to expected earnings per share over the next 12 months. It is the most widely used valuation metric for the U.S. stock market.

The S&P 500 forward P/E at 20.3x has declined from its recent highs but remains above the 25-year average of approximately 16.5x. Markets are pricing in solid earnings growth but are no longer at 'euphoric' valuations. For executives evaluating M&A, stock compensation, or capital market activity, current valuations suggest a market that is fairly valued to modestly expensive — not cheap, but not at bubble levels either.

Methodology: Forward P/E divides the current index price by the consensus estimate of aggregate earnings per share over the next 12 months. Analysts at major banks and research firms provide earnings estimates for individual S&P 500 companies, which are aggregated by data providers like FactSet, Bloomberg, and S&P Global.

How These Comparisons Are Built

Each pairwise comparison page is statically generated from the live indicator dataset — values, trends, and source links are pre-rendered into HTML at build time. When the underlying dataset refreshes (each indicator on its own publication schedule), the comparison page regenerates automatically. ExecBolt does not estimate, model, or interpolate any reading; every value comes from the publishing agency’s primary release. For the full sourcing approach, citation format, and known limitations, see the methodology page.

For tools that translate macro readings into business outputs (DCF, runway, break-even), see the calculators page. Authoritative external context comes from the Federal Reserve’s FRED database, the U.S. Bureau of Labor Statistics, the U.S. Bureau of Economic Analysis, and the SEC EDGAR system.
