This paper employs a robust portfolio sorting procedure to factor size characteristics into returns. The US size anomaly boils then down to a pure seasonal effect, fully supporting the “tax-loss-selling” hypothesis. We build a long-short calendar trading strategy, easily reproducible by an asset manager, being long the Smallminus-Big (SMB) portfolio in January (or in Q1), staying in cash in Q2 and Q3, and shorting SMB in Q4. The strategy achieves a mean yearly return close to 11% from 1963 to 2019. It does not decay over time, remains steady across all subperiods, and resists to the detection of false discoveries.
