Investors are awakening to the robotics investment theme in droves, boosting the fortunes of some exchange-traded funds (ETFs) along the way. That includes the Global X Robotics & Artificial Intelligence ETF (BOTZ), which celebrated its first anniversary last week. Asset growth in BOTZ has been astronomical, and the ETF has been gaining momentum on that front in recent weeks.

"According to data from ETF.com, by reaching $450 million, BOTZ has become one of just eight ETFs launched since Jan. 1, 2016, to achieve this milestone," according to a statement issued by Global X. "BOTZ has seen accelerated growth in recent months, with Global X announcing on June 12, 2017, that BOTZ had reached $100 million in assets by the end of May."

Growing assets under management tallies are aesthetically pleasing. If nothing else, rising assets tell investors that they are not alone in considering a particular ETF, but what really matters is performance. BOTZ is delivering on that front, too. BOTZ is up nearly 45% year to date and has recently been making a series of all-time highs. The ETF's results easily outpace the performances delivered by the industrial and technology sectors, groups from which many robotics-related investments hail. BOTZ tracks the Indxx Global Robotics & Artificial Intelligence Thematic Index.

"BOTZ offers investors access to a rapidly emerging technological theme of the application of robotics and artificial intelligence around the globe," according to Global X. "The robotics industry is expected to grow 10% per year, eclipsing $80 billion in market size by 2020. The AI market is expected to reach $5.1 billion by 2020, from just $420 million in 2014. As of Sept. 12, 2017, BOTZ has a global focus with more than 70% of its exposure coming from outside of the U.S., including over 45% coming from Japan."

BOTZ reflects the global nature of the robotics industry. Over 46% of the ETF's 30 holdings are Japanese companies, and the U.S. is just one of nine countries represented in the fund. All of the countries found in BOTZ are developed markets. The average market value of the companies on the BOTZ roster is $14 billion, putting the ETF at the lower end of large-cap territory. BOTZ has a price-to-earnings ratio of 28 and a price-to-book value of 3.71, according to issuer data. The top holdings in BOTZ include familiar names such as NVIDIA Corporation (NVDA) and Intuitive Surgical, Inc. (ISRG). (For more, see: Investing in Robotics Through ETFs and Stocks.)
