Definition
Thematic ETFs target investment themes that cut across traditional sector boundaries. Examples include artificial intelligence, clean energy, cybersecurity, genomics, and cloud computing. While they can capture powerful secular trends, thematic ETFs tend to launch after themes become popular (buying high), have higher fees, and are less diversified than broad market funds.
lightbulb Example
An AI-themed ETF holds 50 companies across tech, healthcare, and industrials that derive significant revenue from AI applications. At 0.45% expense ratio, it captures the AI trend but launched after many holdings had already appreciated 100%+.
