 Over the last few years, the rewards have kept on coming investors way. The SP 500, considered a representation of the broader stock market, is up 16.5 over the last 52 weeks. In addition, the index has posted an average gain of 10.2 and 15.3 per year over the last five and ten years, respectively. So, everything seems hunky-dory on Wall Street.Unfortunately, this is not actually the case. According to Dalbar, a financial services market research firm, the average investor typically earns significantly less than the market. For example, over the 30-year period through 2019, the SP 500 returned an average of 9.96, while Dalbar estimated the average stock fund investor only earned 5.04 per year. This finding has been witnessed over and over again regardless of the time frame used in the study.Dalbar believes the main reason for this is psychological. He cites behaviors such as panic selling and not adapting to a changing market that lead to poor investment decisions. For this reason, an investor needs better strategies.One way to invest without being influenced by psychological factors is to turn to the experts.
