Hi Tom (Not really that old an AIM guy - Happy Birthday!) Most excellent suggestion but I'm finding two problems. The first is finding the best index to match it to and the second is that they don't have similar enough start dates to make the comparison likely to be accurate.
For example:
SPDR® S&P® Health Care Services ETF XHS Ten year N/A 19.28% 9/28/2011 Guggenheim S&P 500® Equal Weight Health Care ETF RYH Ten year 12.53% 13.13% 11/1/2006 S&P Health Care Services Select Industry Index Ten year N/A 19.73% 9/28/2011
Is RYH lower because it started before the 2008/9 crash which would bring the average down compared to XHS?
where XLP went through at the 2000/2 crash in addition to the 2008/9 one compared to RHS. Does this make a difference. I'm not sure, but I'm guessing it is so.
Of course, your insight to the issue is most welcome.
