Thought this might be of interest to some-

My objectives with respect to the ETFs that I use: 
-How much overlap of stocks in each is there
-Which ones had the most winners/ fewest losers

Here are 6 technology ETFs; and I also added the 
current tech_growers picks from the MI board.
(I could have added a few more ETFs that I like,
but then it would not have all fit in the table below.


1	ARKG	ARK ETF Trust - ARK Genomic Revolution ETF
2	ARKK	ARK Innovation ETF
3	ARKW	ARK Next Generation Internet ETF
4	IGV	iShares Expanded Tech-Software Sector ETF
5	PBW	Invesco WilderHill Clean Energy ETF
6	XITK	SPDR FactSet Innovative Technology ETF

If you want to know more about each fund, 
such as % holdings in each sector, go to
marketwatch.com, search for the ETF and the click on "holdings"
Example:
https://www.marketwatch.com/investing/fund/arkg/holdings?mod...

Took the top 25 holdings for each and then got
their 1 month and 3 month  % price change.
Data sorted by 3 mo. price change.

Looking at the top 20 positions of the 3 month % change, here is 
a count  of how the ETFs fared-

# in the top 20
	arkg	arkk	arkw	igv	pbw  tech_grow	xitk				

	6	5	3	1	7	6	3


PBW had 7 in the top 20 3 month returns.

This my take-away from this study: 
BUY some more PBW (it also had the fewest of the low returners)
Also, not a lot of overlap among them
so if you get several, you'll be in good shape.
