| Pattern | Evidence | Reliability |
|---|---|---|
| Yield Curve Inversion → Recession | Inverted before every recession since 1970 (1973, 1980, 1989, 2000, 2006, 2019, 2022). Lead time: 6-24 months. | |
| Fed Hike Cycle → Market Top | S&P peaked within 6-18 months of last hike in 6 of 8 cycles since 1970 | |
| CPI Above 5% → Forced Fed Action | Every time CPI exceeded 5%, Fed hiked aggressively within 6 months (1973, 1979, 2022) | |
| Unemployment Below 4% → Overheating Signal | Sub-4% unemployment preceded corrections in 2000, 2007, 2020, 2022 | |
| Oil Shock → Stagflation → Deep Bear | 1973 (-48%), 1990 (-20%), 2022 (amplifier). Oil is the most reliable external trigger. | |
| "Fed Pivot" → Rally | Markets rallied within 3-6 months of first rate cut in every cycle since 1982 | |
| Fastest Drops Recover Fastest | 1987 (-34%, recovered 20mo), COVID (-34%, recovered 5mo). Slow grinds (2000-02, 2007-09) take years. | |
| Dual Trigger (Fed + World) = Deepest | Worst corrections combine Fed policy error with external shock: 1973(-48%), 2000(-49%), 2008(-57%), 2022(-25%) |
