Performance wise there is not much diffs between the 2. I bought DIVTRX 15 months ago and so far I have lost 4%. Had I bought STXIND at the same time, I would also have lost 4%. (no divies included)
Only the YTD chart shows DIVTRX leading by 23%.
The 2Y chart shows both at a gain of 5%.
The 3 year shows both at a gain of 28% although the DIVTRX is not quite 3 years old yet.
So performance wise, both are apples from the same tree.
One must also take into consideration that the STXIND was the best performing ETF for many years and when the economy improves and political noise subsides, STXIND may well regain that place. DIVTRX has not got enough history as yet.
