It is a data and hardware ETF that is pretty much tied to the future success of crypto and artificial intelligence. High volatility, high risk/high reward returns here in my opinion.
The fund is more expensive than the S&P 500 on an overall basis all while expecting to grow earnings at a lower pace that the S&P 500 over the next few years. I don't necessarily see it as a good risk/reward trade-off. If everything goes right for a lot of these smaller speculative companies and crypto keeps ripping upwards it will do well. But if they don't, the bottom could easily fall out of a lot of the holdings and thus the fund.
Not one I'd be looking to add unless I had a very high appetite for risk and willing to take a loss.
