S. Cleary et M. Inglis, MOMENTUM IN CANADIAN STOCK RETURNS, Canadian journal of the Administrative Sciences Association of Canada, 15(3), 1998, pp. 279-291
Empirical evidence suggests that U.S. and Canadian stock returns follo
w predictable patterns over a short-term horizon. In particular; abnor
mal profits could have been generated by purchasing previous strong pe
rformers and selling previous poor performers. Our evidence suggests t
hat a portion of this profitability represents appropriate compensatio
n for risk and risk premiums that vary through time. We also examine t
he impact of transactions costs on the implementation of this strategy
and find it may nor be exploitable by the average retail investor fac
ing higher levels of transactions costs. However sensitivity analysis
indicates that momentum trading may have merit for more nimble traders
facing lower transactions costs.
