DRUP selects a concentrated group of U.S. large-cap stocks with high gross margins and high R&D expenses. Its expense ratio is 0.60% and the ETF has $59 million in assets. Additional factors like patent value, sales growth, and increasing gross margins drive DRUP's selections, and I was able to verify it outperforms the Invesco QQQ ETF on most metrics. Performance has been disappointing but sourced mainly to 2020 and 2023, two unusual years. I expect better performance moving forward based on DRUP's solid combination of growth, quality, and value.
