I've been trying to find data on various ASX indicies - and looking at the information on the ASX and Standard and Poors websites, they seem to refer to an "accumulation index" as being a separate (but related) entity to the base index. The description from S&P states something like they just add back the value of distributions when calculating the accumulation index - which by implication, is NOT done for the standard index. So, why doesn't anyone publish data on the accumulation indicies ? They aren't listed on the ASX or S&P websites (although S&P publish tables with annual returns), nor does Yahoo have a separate listing for accumulation index data. ... or am I misunderstanding the difference between the two ? The reason I want this info is that some managed funds benchmark their performance against an accumulation index - I'd like to be able to chart this, but I can't find data for it like I can for a regular index.
