Could you link to how that measurement was taken? Because I very much want to know whether it counts things like mutual funds, or whether it only measures direct ownership of stocks. E.g. I have a bunch (though not all) of my retirement savings in an index fund that owns partial shares of the top 500 US companies (as listed by Standard & Poor's). So depending on how that S&P 500 fund is measured in those statistics, I either own shares in the top 500 companies, or I'm counted as not owning any shares. The latter would produce a very misleading statistic, because I am very much not the only person who invests in the stock market via mutual funds.

So a link would be much appreciated, in order to judge the quality of the info. As it is, I'm skeptical that the info is accurate, precisely because mutual funds are so wildly popular among the middle-class people I know (none of whom are in the top 10%, though most of them would likely be in the top 50%).
