  4. 4. s Definition of Beta In general Beta represents the market return (Risk Premium) of an asset class Depending on investor’s objectives the Beta could be defined as: the return of the stock market (DJ Industrial Average Index) the return of the bond market (U.S. Treasury Note) the return of the commodity market (DJ AIG Commodity Index) the return of the currency market (EUR/USD Exchange Rate) the return of investor‘s liabilities (Liability Index = Zero Coupon Bonds) Depending on the way investors take exposure to Beta we could distinguish between: Traditional Beta, i.e. the long exposure through buy and hold of futures, ETFs, etc. Alternative Beta, i.e. the rotation between the traditional betas and taking advantage of short exposure (CS Tremont Hedge Fund Index) 11 08 4

  10. 10. s Definition of Alpha In general Alpha represents the excess return vs. a given benchmark Per definition Alpha can not be replaced or explained by the existing traditional and alternative Betas, i.e. it has a very low correlation to Beta Alpha can only be generated by taking active bets and is subject to manager’s skills, i.e. Know-How and technology Depending on investor’s objectives we can distinguish between: Relative Alpha, i.e. the relative out-performance against a given benchmark which is usually measured by the information ratio Absolute Alpha, i.e. the absolute excess return above a pre-defined threshold return usually measured by the Sharpe Ratio An example for a commodity Alpha prepared for this presentation is the fin4cast Commodity Index which benefits from long and short positions in 13 liquid commodity futures 11 08 10

  37. 37. s Commodity indices used in the presentation Goldman Sachs Commodity Index: The S&P GSCI™ is a composite index of commodity sector returns representing an unleveraged, long-only investment in commodity futures that is broadly diversified across the spectrum of commodities (Energy 73.86%, Metals 8.73%, Agriculture 13.14%, Live Stock 4.26%) . The returns are calculated on a fully collateralized basis with full reinvestment. The combination of these attributes provides investors with a representative and realistic picture of realizable returns attainable in the commodities markets. Individual components qualify for inclusion in the S&P GSCI™ on the basis of liquidity and are weighted by their respective world production quantities. The principles behind the construction of the index are public and designed to allow easy and cost-efficient investment implementation. Possible means of implementation include the purchase of S&P GSCI™ related instruments, such as the S&P GSCI™ futures contract traded on the Chicago Mercantile Exchange (CME) or over-the-counter derivatives, or the direct purchase of the underlying futures contracts. The Dow Jones - AIG Commodity Index (DJ-AIGCI)® is composed of futures contracts on 19 physical commodities. The component weightings are also determined by several rules designed to insure diversified commodity exposure (Energy 33%, Metals 26.2%, Agriculture 30.3%, Live Stock 10.5%). Investors may invest in the Dow Jones AIG Commodity Index buy purchasing futures contracts traded on CBOT (Chicago Board of Trade). Alternatively, they may also purchase Pimco Commodity Real Return Fund, which mimics the returns of the Dow Jones AIG Commodity Index. The PHLX Gold and Silver Index is a capitalization-weighted index composed of the common stocks of nine companies in the gold and silver mining index. The index is a product of the Philadelphia Stock Exchange and began trading in January 1979 with an initial value of 100. 11 08 37
