State Street SPDR S&P Kensho Intelligent Structures ETF(AMEX:SIMS)

SIMS is passively-managed to provide exposure to firms which the index provider defines as companies involved in: smart building infrastructure, smart power grids, intelligent transportation infrastructure, or intelligent water infrastructure. Each company is further classified as either core or non-core, depending on the level of involvement in innovative infrastructure. The index is initially equally weighted, but then tilts the overall portfolio weight towards core firms by 20%. As a result, pure plays are overweighted.
