New York (CNN Business)BlackRock has an ETF for virtually any niche you might want to invest in. Now BlackRock has launched a new suite of products so investors can tackle so-called “megatrends.”The new exchange-traded funds promise to be the purest way to access emerging areas, including robotics and AI, genomics, energy innovation and the developing world’s emerging middle class.To profit from investing in a trend, you have to go beyond investing in just one stock, according to BlackRock (BLK).You shouldn’t buy only Tesla (TSLA) if you want to get exposure to electric and self-driving vehicles, said Armando Senra, head of US, Canada and Latin America iShares.”It’s who makes the batteries, who makes the sensors. You’ll be buying the lithium. When you’re buying these themes, you’re really going deep,” Senra said.
