This paper shows how the risk of price declines in stock market invest
ments can be reduced by using a sequential signal system to determine
when to buy or sell. The signals are based on growth rates in long-lea
ding indexes and in broad stock price indexes. Tests of the method dur
ing the past 20 years or more are shown for Australia, France, Germany
, Japan, the UK and the USA. In some instances the reduction in risk (
measured in terms of volatility of rates of return) is achieved at the
cost of a lower average rate of return, but in other cases the averag
e rate of return may be significantly higher than that obtained by a s
imple buy-and-hold strategy.
