ROBO, though, focuses more on U.S. companies at 40% of the portfolio, followed by Japan 30%, Germany 6%, Taiwan 6% and Switzerland 4%. Its portfolio is also more diversified with 84 component holdings, and top components including Aerovironment 2.7%, Daifuku 2.5% and Harmonic Drive Systems 2.3%.
Along with its greater U.S. focus and more diversified portfolio, ROBO has a larger tilt toward mid- and small-sized companies when compared to BOTZ. Specifically, ROBO’s market-cap weights include mega-caps 12.0%, large-caps 18.5%, mid-caps 42.8%, small-caps 16.9% and micro-caps 9.8%. In contrast, BOTZ focus on more established companies, including mega-caps 47.4%, large-caps 21.5%, mid-caps 20.4%, small-cap 8.9% and micro-caps 1.8%, which may have contributed to its outperformance in a year where smaller companies have fallen behind the large-cap segment.
