U.S. Dollar Index (DXY) vs S&P 500 Price-to-Earnings Ratio (Forward)

How These Two Indicators Relate

Dollar Index sits in the trade 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.

Both readings are currently moving lower. Dollar Index has moved lower -0.10 since the prior release; S&P 500 P/E has moved lower -1.20. When two related indicators decline together, the move usually reflects a real economic shift rather than measurement noise.

What U.S. Dollar Index (DXY) Measures

The U.S. Dollar Index measures the value of the U.S. dollar against a basket of major currencies (euro, yen, pound, Canadian dollar, Swedish krona, Swiss franc). It reflects the dollar's purchasing power in international markets.

The dollar has weakened to 103.0, down from a January peak of 109.4. A weaker dollar is mixed for U.S. businesses: it makes American exports more competitive abroad and boosts the dollar value of foreign earnings (positive for multinationals), but it increases the cost of imported goods and raw materials. For executives at companies with significant international revenue, dollar weakness is generally a tailwind for reported earnings.

Methodology: The DXY is a weighted geometric mean of the dollar's value against six currencies: Euro (57.6%), Japanese Yen (13.6%), British Pound (11.9%), Canadian Dollar (9.1%), Swedish Krona (4.2%), and Swiss Franc (3.6%). It was established in 1973 with a base of 100. The Federal Reserve also publishes broader trade-weighted dollar indices. Source: FRED at the St. Louis Fed (series DTWEXBGS).

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.
