There are more and more thematic ASX ETFs becoming available to investors.
When these targeted themes rally, investors can capture market-beating returns.
However, on the flip side, when these sectors face headwinds, losses can also be amplified.

There are several ASX ETFs that target these sectors.
After falling significantly this year, let's look at funds that could be undervalued right now.
