We extend the empirical analysis of hot hands in sports to horse racing, using the winning streaks of a sample of jockeys riding in Australia. Grouping jockeys by strike rate (win percentage), we find evidence of hot hands across almost all strike rates. But considering jockeys individually, only a minority exhibit hot hands. A wagering strategy based on hot hands yields a negative return overall and for most hot hand jockeys, although some do yield a positive return. We conclude that hot hands are present but not ubiquitous and that this is generally recognised in the betting market.
