SPDR S&P Kensho Smart Mobility ETF(AMEX:HAIL)

HAIL focuses on US-listed smart transportation firms, which the index provider defines as those companies whose products or services are advancing in the following areas: autonomous and electric vehicle technologies, drone technologies used for commercial and civilian applications, and advanced transportation tracking and transport optimization systems. To determine its constituents, the underlying index uses natural language processing (NLP) to scan companies most recent filings in order to identify terms or phrases that support the index objective, along with additional size and liquidity screens. Eligible companies are then classified as core or non-core, depending on the level of involvement in innovative transportation. The index initially weights each stock equally, but then re-assigns 20% of the non-core firms weight equally to the core firms. As a result, pure plays are overweighted. The index rebalances semi-annually.
