Does it make sense to talk about an ETF or index in terms of technical indicators?
With the disclaimer that I am not a technician, I'd answer yes, it does. SPY (for clarification, an ETF that reflects the S&P 500 index) has dividends, and earnings, therefore a P/E and dividend yield. It would follow that the tools technicians use, such as moving averages, support and resistance levels also apply.  Keep in mind, each and every year, one can take the S&P stocks and break them up, into quintiles or deciles based on return and show that not all stock move in unison. You can break up by industry as well which is what the SPDRs aim to do, and observe the movement of those sub-groups.  But, no, not all the stocks will perform the way the index is predicted to.  (Note - If a technician wishes to correct any key points here, you are welcome to add a note, hopefully, my answer was not biased)
