Look at my watch! Continuous information and the momentum effect in the market for luxury watches
摘要
We find a consistent momentum return premium of 1.25% p.m. in the global market for luxury watches between June 2017 and September 2024. Investors are inattentive to a series of frequent gradual returns during the momentum formation period and draw more attention to infrequent large returns. For that reason, long-only momentum portfolio profits decrease from 1.26% for luxury watches with continuous information during their formation period to 0.09% for watches with discrete information, but similar cumulative formation-period returns. Conditional on continuous information, momentum profits covary with the market state, return dispersion, and investor sentiment.
