The ETF's implied volatility exceeds 90%, with daily swings near 6%, and its P/E of 9.2x may signal peak-cycle risk for memory-chip companies.
For years, thematic investing offered investors a different look at traditional growth exposure that included artificial intelligence (AI) and machine learning. While these themes have now become commonplace, time and evolution are creating a new crop of thematic opportunities in memory, robotics, and space exploration.
