BLCN is one of the first ETFs to focus on blockchain technology. The fund tracks an index of global companies committed to blockchain development. Although not an active fund, the index committee has wide discretion in selecting companies. The main criteria used to evaluate a company is the level of material resources it has committed to researching, developing, supporting, and expanding the use of blockchain technology. All criteria are eventually rolled up to form the BlockChain Score. The index includes the 50-100 highest scoring companies, giving greater weight to higher-scoring companies. Because blockchain technology has uses across varying industries, BLCN could have exposure to multiple sectors. The index is reconstituted and rebalanced semi-annually. Note: The fund was acquired by SRN Advisors. Prior to November 23, 2020, the fund and index names were Reality Shares Nasdaq NexGen Economy ETF and Reality Shares Nasdaq Blockchain Economy Index, respectively.
