Global stocks have been great sources of trading and investment opportunities. In 2015 while USA indexes were sideways China had a terrific rally and then huge collapse. These moves were trade-able on ETFs (thin volume but there). EEM had a huge drop in the 2nd half of 2015, and Brazil has led most of 2016 in percentage return among country / index / sector ETFs.
There are a lot of possibilities but first let's divide between developed and emerging. Developed often means Europe with a focus on Germany and then Japan; with key benchmark indexes of DAX and NKY. If you are an American retail investor, then the choice is EWG & EWJ versus hedged versions. I tend to not mention these so much even though I have at other times had a significant focus on Japan - the main reason is these tend to be correlated with USA indexes and moves are more a matter of magnitude than direction and timing. Mostly, correlated not always. Regardless, if you are playing anything outside the USA, it is best to emphasize pivots and technicals on what you actually own versus an index.
I'm sure there are people out there who want to include all the available country ETFs and this could be a worthwhile exercise, but I think quite a lot moves together anyway and I'd rather stick to the main vehicles.
Moving onto emerging markets the big ones I track are:
FXI - China via Hong Kong
EEM - popular emerging index
INDA - India
RSX - Russia
EWZ - Brazil
ACWI - Global benchmark, kind of like NYA functions for USA indexes
Shanghai Comp via XGY0 on trading view, close enough, and tradeable through ETFs
We could also get into China tech cos and corresponding ETFs because they are significant in market cap but let's save that for another day.
The main point is if we are positioning and selecting 1-2 USA mains, 1-2 USA sectors, 1-2 global indexes, 1-2 currency commodity positions, then a selected 0-3 as shorts then we are at about 10 different vehicles maximum. I'm sure most people have more but to me this right for an active trading account.
For each global vehicle - weekly technical chart, weekly long term pivot chart, and daily pivot chart.
FXI
Monthly chart at several MAs clustered, so an interesting area to watch: 20MA 37.52, 50MA 37.92, 100MA 37.85.
