Replication strategies Optimized physical replication

In the case of optimized physical replication, the ETF holds a sample of the securities in the underlying index. Analytical tools and mathematical optimization procedures are implemented to define a subset of the index constituents that will achieve a return similar to that of the original stocks represented in the index. The optimized physical replication method can be utilized to increase liquidity and minimize tracking error.

The optimized physical replication method is particularly suitable for very broad-based indices. For example, the MSCI World Index comprises approximately 1,600 stocks from a variety of markets, jurisdictions and currency zones. Accordingly, full physical replication of the index would involve high transaction costs. A number of these securities are not very liquid or have only minimal impact on the performance of the Index due to their low weighting. Transaction costs can be reduced by excluding these securities.

  1. The ETF is in physical possession of a subset of the index components, which is used either for very broad-based indices or for indices with illiquid securities
  2. Optimization procedures are implemented in order to lower transaction costs, increase liquidity and minimize tracking error
  3. Some ETFs lend out securities from their portfolio for a fee

Securities lending

A number of select physically replicated ETFs engage in securities lending in order to generate additional returns and reduce investors' net costs, whereby the ETF's securities are lent out for a fee. Securities lending transactions of UBS ETFs are overcollateralized to a minimum of 105%.
