KGRN tracks an index of large-, mid-, and small-cap Chinese companies that derive a significant portion of their revenue from clean technology, specifically from five environmental themes: alternative energy, energy efficiency, sustainable water, green building, and pollution prevention. Potential holdings include A-shares, as well as stocks listed in Hong Kong or outside China. Holdings are market-cap-weighted, with each security weight capped at 10%. Securities having 5% or more weight may not collectively exceed 40% weight of the Index. The resulting portfolio is very narrow, with just a few dozen holdings, favoring small-cap names in the utilities and real estate sectors. The index is rebalanced quarterly. Prior to March 19, 2021, the fund was called the KraneShares MSCI China Environment Index ETF. The name change aims to better reflect the funds clean-tech exposure and has no effect on the funds strategy.
