CAPM vs APT Under Varying Interest Rate Regimes
Here's a question: When central banks abruptly reverse rate-hike cycles like in 2023, which risk model better predicts equity reallocations — the CAPM adjusted for risk-free rate shifts or the Arbitrage Pricing Theory? CAPM's beta coefficients often destabilize after Fed fund rate pivots because of compounding duration risk exposures in long-duration sectors like real estate. Meanwhile APT's multifactor approach captures macroeconomic surprises better but lacks consensus on optimal factor weighting formulas. For instance, should housing price inflation get more weight in APT than consumer exuberance metrics when modeling rate-sparse scenarios? Has AlphaGen's Q4 asset flow data between 7% and 4% Fed fund thresholds shown clearer CAPM deviations or APT breakdowns? Thoughts before the May CPI report?
