This article https://www.thebalance.com/good-rate-roi-357326 sugggests shares typically generate about 7% per year, property 10%. Looking at FTSE100 as a whole, returns ave around 3.9% over last 5 years, 8.8% over 10 years , 3.2% a year over 20 years and 6.4% over 25 years but *only with dividends reinvested*. Without dividends its 0% over last 5 years according to https://www.ig.com/uk/trading-strategie ... 00--190318. US equivalent is here https://www.getrichslowly.org/stock-market-returns/. There is also inflation and tax to consider.
So coming to my question, what percentage of stockmarket investors would make the following (after tax, including dividends if applicable) consisently (?ave over 5 years). Before some giant claims roll in remember Berkshire Hathaway averages 20.5% (albeit for more than 50years!)
-10% or lower
-10% to 0%
0 to 5% (slightly below market ave)
5 to 10% (slightly above)
10 to 20% (significantly above)
20% or higher (way above)
Most people expect 10% but realistically? https://www.thisismoney.co.uk/money/inv ... -year.html
This question reminds me of when during the poker boom it was suggested that under 5% of online poker players were profitable. There followed much indignation, but despite the massive data harvesting going on at the time absolutely no refutation.
What the game pays out on average may prove to be a very bad guide to what the average player is paid, and the chances of ever getting better than self reported data on a significant number of investors seem somewhat slim.
Indeed.
Looking at the last 50 years, the MSCI World index gross annualised return, dividends reinvested, was 10.9%. Some of that was due to the depreciation of the pound against other currencies, which may or may not repeat itself over the next 50 years. In dollar terms the annualised return was 9.6%. So the linked article suggesting 10% is probably not too unrealistic as an expectation for future stock market returns. However, most investment portfolios do worse than average. For example, over the last 10 years, according to SPIVA research, about 90% of US funds underperformed their benchmarks. But it gets worse still. Most private investors significantly underperform the market, for a variety of reasons. You might find this paper on the behaviour of individual investors interesting:

Conclusion
The investors who inhabit the real world and those who populate academic models are distant cousins. In theory, investors hold well-diversified portfolios and trade infrequently so as to minimize taxes and other investment costs. In practice, investors behave differently. They trade frequently and have perverse stock selection ability, incurring unnecessary investment costs and return losses. They tend to sell their winners and hold their losers, generating unnecessary tax liabilities. Many hold poorly diversified portfolios, resulting in unnecessarily high levels of diversifiable risk, and many are unduly influenced by media and past experience. Individual investors who ignore the prescriptive advice to buy and hold low-fee, well-diversified portfolios, generally do so to their detriment.
