R. Hudson et al., A NOTE ON THE WEAK FORM EFFICIENCY OF CAPITAL-MARKETS - THE APPLICATION OF SIMPLE TECHNICAL TRADING RULES TO UK STOCK-PRICES - 1935 TO 1994, Journal of banking & finance, 20(6), 1996, pp. 1121-1132
Brock et al. (1992) found technical trading rules to have predictive a
bility with regards to the Dow Jones Index. The current paper consider
s whether this result can be replicated on UK data. The paper also con
siders whether investors could earn excess returns from technical anal
ysis in a costly trading environment. The paper concludes that althoug
h the technical trading rules examined do have predictive ability in t
erms of UK data, their use would not allow investors to make excess re
turns in the presence of costly trading.
