About ProShares Nanotechnology ETF

TINY is a passively managed fund that invests in securities from developed countries perceived to help businesses use nanotechnology to transform lives and revolutionize different industries. Companies considered should be involved in the production, application, development, or promotion of nanotechnologies. Using natural language processing algorithm, filings and public information are scanned to identify companies that have or are expected to have significant exposure to nanotechnology. Companies are then scored and ranked based on their level of exposure. Only the 30 highest-ranking companies are selected. Securities are weighted by market cap with a maximum limit of 4.5%. The index is reconstituted and rebalanced semi-annually in May and November.
