Quote from tradingjournals:
You made excellent posts. I would like to add that the numbers could be worse as the analysis did not take into account the survivor bias in the dow.
I would not be surprised (in fact that is what I would expect) if the compounded return is negative if one includes all stocks that were ever listed in the markets.
Those who make the money in the markets are the IPO owners.
I didn't think about the survivor bias in indexes, but I think their quotes are still quite representative of the behaviour of all stocks. See for example NASDAQ100 and NASDAQ Composite (for many indexes around the world you find both the selection and the total).
I took the DJIA as a representative for all stocks because we have a lot of data.
I don't think we could have a negative return,but I don't know.
Actually, we should think about what happens to an index and to a real investor portfolio when a firm fails (for example,General Motors).
As I said,what is not representative at all is the dividend yield.
