ROBO ETF outperforms BOTZ with broader robotics exposure and lower volatility in 2026

The ROBO Global Robotics & Automation Index ETF (ROBO) and the Global X Robotics & Artificial Intelligence ETF (BOTZ) offer different approaches to investing in robotics and AI. ROBO provides broader diversification with 74 international holdings and a modified-equal-weight strategy, resulting in lower portfolio concentration and geographic exposure mainly in North America. BOTZ is more concentrated in its top 10 holdings and leans heavily on large-cap Asian tech stocks. In 2026, ROBO returned 14.5% year-to-date, outperforming BOTZ's -3.9%, while also showing lower volatility. Investors should consider these differences in concentration, geography, and cost when choosing between the two ETFs.
