What are your thoughts on investing in Thematic Funds?

I've been hearing a lot about thematic funds lately and I'm curious to know how other traders feel about them. On one hand, the idea of investing based on trends like tech innovation, sustainability, or healthcare advancements sounds exciting and potentially lucrative. But I can't help but wonder about the risks involved. Have any of you had experience with them? How do you choose which themes to invest in? Also, do you think they perform better than traditional funds in the long run? I'm trying to weigh the pros and cons before diving in. Would love to hear your insights!
