Here is a link to all the ETFs or at least most of them. Scroll down a little on the left to the double or triple Index ETFS. As an example the triple bull Russell small cap ETF:URTY in mid June was about $75 and hit $96 today. One doesn't want to be on the wrong side of one of these. If squeamish one can trade double ETFs or even single ETFs on the Indexes. There are also many commodity ETFs as well in single or double such as Silver and Gold etc. Scroll all the way down for the list of ETFs and Indexes and Commodities. And the bottom right is all the breadth indicators and point a figure bullish and bearish percent charts etc. It's free for a lot of worthwhile data.
