Its definitley wrong to post here this report. As this is for someone who has his chunk of money available to invest, than investing at once will win you most of the years even though it comes with considerable higher risk and volatilty as the report itself notes. But someone who starts to invest than its DEFINITLEY worth to invest every small amount immediatley than to accumalate a considerable chunk and than invest it
You were saying how cost averaging was better than (i used the word correctly here) lump sum and therefore when i showed you that there were ten year periods with losses it wasn't what you meant. Now you are changing again?
Either you are having difficulty expressing what you really mean or you don't know what you are talking about and keep on changing. Both mean that there is nothing useful to be taken from what you wrote here and should be ignored.
