How to interpret this

These descriptive statistics compare how direction and magnitude differed across observed cases under the same condition. Positive values indicate dollar strength and yen weakness; negative values indicate dollar weakness and yen strength. A particular season or a past sharp move cannot be assumed to determine subsequent exchange rates. No comparison with unconditional changes over the full period or separate validation sample was performed, so no outperformance is claimed.

These are changes in spot exchange-rate or dollar-index quotes, not investment returns including dividends, interest, carry, transaction costs and foreign-exchange spreads. Examining multiple conditions within the same sample can produce chance findings. Thresholds are not natural economic laws, and results differ with other criteria. Follow-up windows within the same pattern do not overlap, but statistical independence is not guaranteed and cases can overlap across patterns. Federal Reserve data are published after their observation dates and may be revised, so these results do not establish real-time tradability or predictive power.

Conditions, methodology and sources

Examines valid daily observations from 2007-01-01~2026-10-02 in sequence, using 2006 data for preliminary calculations. The condition observation date is the first crossing when the change versus 21 valid observations earlier reaches +5% or higher. The same condition must not have been met on the preceding day. After selecting a case, no other case is selected from that date through the next 21 valid observations; only a new subsequent crossing is selected. All cases meeting this rule are included, without selecting by the direction of the outcome. The endpoint of the next 21 valid observations is not used to select the condition. The 21 observations represent roughly a month, not a calendar month; cases with insufficient follow-up observations remain ongoing. Source data are the Federal Reserve’s H.10 daily data. Missing status ND(-9999) is excluded without interpolation. Change is calculated as (ending observation / starting observation - 1) × 100 and stored to 8 decimal places. Quotes are yen per 1 dollar, with positive values indicating dollar strength and yen weakness; negative values indicate dollar weakness and yen strength. Dates are source observation reference dates, not publication times or times when trading was possible. The source is revised data from the release of 2026-10-05, not a real-time investment-strategy backtest.
