The world’s first cybersecurity ETF, the PureFunds ISE Cyber Security ETF (HACK) was created to provide the market with a transparent vehicle to invest in the cyber security industry, according to New York City based PureFunds. ‘Pure’ seemingly comes from the catchphrase ‘pure-play’ which is used to describe companies with a single-minded focus on one market. A careful examination of the HACK’s holdings suggest that ‘mostly cyber’, or ‘some cyber’, are more accurate descriptions of the groundbreaking HACK ETF.
