The paper focuses on empirical testing and the use of the regular investment, particularly on the value averaging investment method on real data from the US stock market in the years 1990-2013. The 23-year period was chosen because of a consistently interesting situation in the market and so this regular investment method could be tested to see how it works in a bull (expansion) period and a bear (recession) period. The analysis is focused on results obtained by using this investment method from the viewpoint of return and risk on selected investment horizons (short-term 1 year, medium-term 5 years and long-term 10 years). The selected aim is reached by using the ratio between profi t and risk. The revenue-risk profi le is the ratio of the average annual profi t rate measured for each investment by the internal rate of return and average annual risk expressed by selective standard deviation. The obtained results show that regular investment is suitable for a long investment horizon or the longer the investment horizon, the better the revenue-risk ratio (Sharpe ratio). According to the results obtained, specifi c investment recommendations are presented in the conclusion, e.g. if this investment method is suitable for a long investment period, if it is better to use value averaging for a growing, sinking or sluggish market, etc.
