US vs Emerging Markets: SPY/EEM Ratio (2003-2026)

Data source: Yahoo Finance daily adjusted close prices via yfinance. Tickers: SPY (S&P 500 ETF) and EEM (iShares MSCI Emerging Markets ETF). Prices are split- and dividend-adjusted.

Summary

The SPY/EEM ratio measures how many shares of EEM one share of SPY can buy. A rising ratio means US is outperforming emerging markets; a falling ratio means EM is outperforming.

Three distinct eras:

  1. 2003-2010: EM Dominance — Ratio fell from 6.3 to 2.8. The BRIC boom drove massive EM outperformance. China's WTO entry, commodity supercycle, and rapid industrialization powered EM equities.

  2. 2011-2024: US Dominance — Ratio rose from 2.8 to 14.2 (peak). US tech-led growth, QE tailwinds, strong dollar, and FAANG/Magnificent 7 drove relentless US outperformance. EM struggled with China slowdown, commodity bust, and USD strength.

  3. 2025-present: EM Recovery? — Ratio pulled back from 14.2 to 11.2. Early signs of EM catching up, possibly driven by China stimulus, AI supply chain diversification, and US valuation stretch.
