Hi there,
We don't recommend any particular one. My suggestion would be to go to the emerge website and look at the top 10 holdings of each. You will see there is overlap between many of them, so you want to make sure that you are choosing wisely. By looking at the top 10, you can get a sense of what the holdings will look like.
Personally, I do like the Fintech Innovation ETF because I am a big fan of that industry. Think companies like LSPD, SHOP, NVEI (all of which I own). The Genomics & Biotech ETF attracted alot of investors because of the popularity of genomics but for me - jury is still out on that one. The others all have their benefits and similarities, so best to look at the holdings first.
As for Space - it might be one I'd consider jumping in to but in this environment, i may hold off till i see the markets stabilize a little.
