understand poor performing stocks (Twitter) in SP 500 are replaced with high performance regularly (Amazon) so it final % are manipulated.
You have to understand that the S&P indexes are a managed momo strategy to benchmark your performance.
I didn't say it did. I think it's a great benchmark. If you can't outperform the market, why are you trading?
of the original 500 S&P stocks, 456 have been replaced - many multiple of times over and over for better performing stocks. The original 500 return is -11,900%. Can you beat that return?
LOL Yup I think I can. Since 1994 a retail trader could afford to trade the index with SPY. It's a good benchmark as it allows you to compare your portfolio with the index. If you cannot outperform the index, a portfolio of the 500 or so best stocks in the US, why are you trading?
it seems to be based on the eventual fate of the many, many companies that were removed from SP 500 since 1929 (https://www.dogsofthedow.com/djdelete.htm) and replaced with robust ones. So many of these companies went on to declare bankruptcy (i.e. Sears, Radio Shack) = 100% lost value x all those that failed or are now at marginal value. When their values are complied, numbers are not so good.
