Abstract: This paper studies investors' strategy change frequency and their wealth accumulation by financial investments. Artificial investors are put into a real stock market. They trade S&P 500 following common strategies in practice. Fundamental analysis generally surpasses technical analysis in all market situa- tions except boom periods. Though investors' strategy change behavior, which is driven by the past performance of strategies, seems reasonable, a faster strat- egy change does not guarantee a higher final wealth. Active strategy change hurts investor' wealth in bear markets and in markets with major trend rever- sals. In bull markets, both fast and slow strategy change behaviors work better than a moderate speed of strategy change. A detailed decomposition of wealth accumulation via financial investment shows the dependence of wealth on in- vestors' past transactions. This may explain the relation between investors' strategy change frequency and their wealth.
