We study compound returns to nearly 62,000 global common stocks during the 1990 to 2018 period, documenting that the majority, 56% of US stocks and 61% of non-US stocks, under perform one-month US Treasury bills over the full sample. Focusing on aggregate shareholder wealth creation measured in US dollars, we find that the top-performing 1.3% of firms account for the $US 44.7 trillion in global stock market wealth creation from 1990 to 2018. Outside the US, less than one percent of firms account for the $US 16.0 trillion in net wealth creation. These results highlight the practical implications of the fact that the distribution of long-run stock returns is strongly positively skewed.
