DB Commodity Booster DJ-UBSCI ETF is linked to the DB Commodity Booster DJ-UBS, which reflects the performance of 19 commodity futures contracts. Currently its weighting is as follows: energy 31.3 per cent, precious metals 11.9 per cent, base metals 25.7 per cent and agriculture 31.1 per cent, the bank said in a statement.

The DB Commodity Booster DJ-UBSCI Index applies Deutsche Bank’s proprietary “optimum yield” methodology, which seeks to optimise returns when the underlying futures contracts are “rolled” at their expiry and benefit from any differences between current and future prices for the commodities contracts. The optimum yield technology seeks to maximise the roll returns in back-dated markets and minimise the losses from rolling in contangoed markets, the bank said in its statement.

“The listing of the DB Commodity Booster DJ-UBSCI ETF offers instant exposure to a broad basket of commodities in a low cost and efficient way. The optimised yield approach in the index is a further attraction as it provides a way to roll the futures contracts to optimise returns,” said Thorsten Michalik, head of db x-trackers.

ETFs, which are listed and traded like individual stocks, give investors access to a variety of asset classes and market indices without the investor having to hold the underlying assets. The sector has grown rapidly and ETFs already typically charge a significantly lower fee than conventional index-tracking funds.

db x-trackers was launched in January 2007 and has currently €20 billion ($28 billion) of assets under management.
