Housing Market Signals (derived)
Signals derived from FRED's US housing series: 30-period annualized volatility of changes, 3-month momentum, year-over-year percent change (the Case-Shiller boom/bust gauge), 3-sigma anomaly flags, naive-drift 1-month forecasts, a per-date cross-series volatility rank, and the permits-to-starts pipeline ratio. Covers HOUST (monthly housing starts), PERMIT (monthly building permits), CSUSHPISA (S&P/Case-Shiller U.S. National Home Price Index), MORTGAGE30US (weekly 30-yr fixed mortgage rate) and HSN1F (monthly new one-family houses sold). All rows are normalized to country_code USA so they join cleanly with US macro data. Raw series: Federal Reserve Bank of St. Louis (FRED).
