β± 19 minute read Β· long-form π
Last reviewed: July 12, 2026 The fastest-growing economies of the last century produced some of the century’s worst stock returns. Emerging markets have lagged for fifteen years mostly because their booming economies issue a flood of new shares.

Strong Dollar and Your ETF: The 20% Effect
A strong dollar drags international ETF returns because funds like VXUS earn in euros, yen, and rupees, then convert those gains into fewer dollars. One NBER study, Obstfeld and Zhou 2023, puts roughly a fifth of emerging-market equity swings on the dollar cycle over two-year stretches. From 2014 through early 2024, developed international stocks more than doubled in local currency but returned 64 percent in dollars. The gap was currency translation, not company performance.

Yield Curve Recession: 60 Years, 1 Big Catch
Last reviewed: June 2026 Wall Street’s most reliable alarm rang in 2022, and four years on, the runway still has not ended.

Why a Strong Jobs Report Can Send Stocks Lower in 2026

Hold-versus-react projections were modeled in Python; the full methodology is open at /editorial-policy/. Sources verified June 2026, with corrections logged and timestamped.

CPI vs PCE: The Gap the News Won’t Tell You
📅 Last reviewed: June 9, 2026 Two gauges leave the same track and drift a little farther apart every year. CPI vs PCE inflation reads like one story until you set the two gauges side by side. The CPI you hear quoted has run about 0.4 percentage point a year hotter than the PCE the Federal Reserve actually targets. Stretched across a 25-year plan, a margin that small can compound into a six-figure swing in real value.
Fed Rate Decision: Why Timing Your Portfolio Costs You
⏱ 22 minute read · long-form The fed rate decision portfolio impact is mostly priced in: Bernanke and Kuttner found the S&P 500 reacts to the surprise, not the announced rate. Their event study put the typical move near 1% per unanticipated quarter-point cut. Because an expected cut is already in prices, selling before a meeting mainly forfeits time in the market. J.P. Morgan Asset Management shows the best days cluster near the worst, so stepping out risks missing the rebound.
