State of the Asset Class

October 16 Picard Angst AG

Where do we find ourselves in the commodity cycle?

• The upswing of the China-driven commodities supercycle peaked in 2011 and has given way to a prolonged downswing

• Global growth has disappointed since the global financial crises. The transition of the Chinese economy from an investment-focused and export-led growth model towards a domestic consumption driven economy implies reduced rates of growth

• In recent years, vastly expanded production capacity incentivized by the commodities boom has met a marked slowdown in commodities demand growth

• Historical analysis suggests an average duration of cyclical commodity downswings of approximately 7 years with concomitant price declines amounting to -40% on average (cf. chart p.4)

• The current downswing has persisted for 5 years and is exhibiting tentative signs of bottoming

• Price declines observed on leading commodities have already reached significantly above average magnitude, e.g. copper -55%, crude oil -65%

• Analysis of the total return of the broad-based Bloomberg Commodity Index indicates a complete reversal of the recent supercycle upswing with the benchmark retreating to levels last seen in 2002. Divergence with spot returns has been exacerbated by the compression of collateral yield as a function of monetary policy response since 2008

• Current market pricing put in relation to marginal production cost curves across sectors suggests an impending acceleration of measures to curtail unprofitable excess capacity clearing the path towards a rebalancing of supply with demand and the commencement of a new cyclical upswing, the initial recovery phase of which is being driven by a rationalization of supply

Summary 36

Why Consider Commodities in the Strategic Asset Allocation?Benefit to the portfolio

Diversification

• Low average correlation with major traditional asset classes equities and bonds

• Historically, the addition of commodities to an equity/bond portfolio has resulted in a sustained increase of risk-adjusted returns

Inflation Protection

• Among all asset classes, commodities exhibit the highest degree of sensitivity with respect to price pressures

Return – Earning the asset class risk premium (beta)

• The cyclicality and lack of cash flow yield from commodities investments raises questions regarding the existence of an asset class risk premium

• Historically, provided a suitable investment strategy that adequately accounts for the cyclicality of the asset class is chosen, a broadly diversified commodity portfolio has achieved equity-like risk-adjusted returns over the long term

The Commodity Beta Risk Premium

October 16 Picard Angst AG

Theories regarding the source of the commodity asset class risk premium

• Keynes' theory of «normal backwardation»

• Risk premium arising out of the insurance function of futures markets: F(t) = E[S(T)] – P(T)

• «Hedging pressure» hypothesis

• Generalization of the theory of normal backwardation to take into account the consumer in addition to the producer perspective with respect to hedging behavior and its impact on roll yield

• Explanation of the shape of the term structure as a function of producer and consumer hedging behavior

• Theory of storage

• Focus on convenience yield as a risk premium and measure of the value of prompt availability of a commodity and its role in determining commodity prices in addition to storage and financing costs

• Diversification return

• Periodic rebalancing generates returns exceeding the weighted sum of portfolio component returns

• The size of diversification return arises as an inverse function of the covariance matrix

Commodity Index Strategies

October 16 Picard Angst AG

From first to second generation beta strategies

First generation index strategies

• Holding contracts situated at the front end of the term structure

• Rolling exposure to the next nearby contract on a frequent basis (as often as monthly)

Second generation index strategies

• Introduced with the objective of mitigating the detrimental impact of contango, which due to the typical curvature of forward curves is most pronounced at the front end of the term structure

• Common approaches

• Forward roll (F1 through F12 adaptations of first generation indices)

• Enhanced seasonal roll (e.g. S&P GSCI Enhanced Commodity Index)

• Constant maturity roll (e.g. UBS Bloomberg CMCI, JP Morgan CCI)

• Optimized implied roll yield (e.g. S&P GSCI Dynamic Roll Commodity Index, Bloomberg Roll Select Commodity Index)

Compositional Deficits of Common Commodity Benchmarks

October 16 Picard Angst AG

Eliminating structural drag and aligning basis risks

• In terms of portfolio composition, standard commodity benchmarks, such as the S&P GSCI and Bloomberg index families, suffer from inadequate construction methodologies focused on production and liquidity statistics

• Disparate sector weightings, e.g. extreme energy overweight in the S&P GSCI due to exclusively taking into account production volume data

• Inclusion of commodity contracts, e.g. US natural gas, whose economic characteristics guarantee losses if held over the long term

• Disregard for the correlation structure among as well as within commodity sectors resulting in unnecessarily high volatility levels or overly expansive portfolio size

• The US dollar based nature of commodities markets raises challenges for European investors looking to take commodity exposure as an inflation hedge

• Basis risks abound with standard commodity benchmarks (e.g. US natural gas, US livestock)

• A dynamic approach to sector allocation can improve significantly on the inflation hedging suitability of commodity investments

Optimizing Commodity Exposure for Inflation Hedging

October 16 Picard Angst AG

Taking into account time-varying inflation sensitivity across commodity sectors

• Inflation sensitivity varies across commodity sectors

• Over the long term, energy and industrial metals exhibit the highest inflation betas

• However, betas do not remain stable over time and are subject to substantial volatility as a function of the economic cycle

• Thus, if exposure to commodities is sought primarily as a defensive investment to take advantage of the pronounced inflation sensitivity of the asset class, portfolio construction should be driven by the time-varying inflation betas of the investment universe, e.g.

• Weighting of sectors energy, industrial metals, precious metals and agriculture (grains, softs) as a function of their respective dynamic inflation betas (subject to a sector weight cap of 70%)

• Monthly rebalancing of sector allocations

• Exclusion of commodity futures contracts from the investment universe that bear no relation to the European economy (notably NYMEX natural gas and the entire livestock sector)

Alternative Risk Premia in Commodities 31

Summary 36

Commodity Beta vs Alternative Risk Premia

October 16 Picard Angst AG 31

Characteristics, return drivers, implementation

Commodity Beta Alternative Risk Premia

Characteristics • cyclical return profile

• inflation protection

• diversification due to on average low correlation with traditional asset classes (equities, bonds)

• absolute returns

• moderate to low volatility

• diversification due to persistently low correlation with traditional asset classes and commodity beta

Return Drivers • risk premium compensating for the assumption of general asset class risk (beta)

• momentum

• value

• carry

• volatility

• etc.

Implementation • long only • long/short market-neutral

Categories of Alternative Risk Premia in Commodities

October 16 Picard Angst AG 32

Sources of systematic commodity alpha

The rich structure of commodity derivatives markets enables investors to access targeted alternative risk premiums by accepting exposure to specific risk factors. Such risk factors typically exhibit behaviour that is largely independent of thegeneral trend in commodity markets (beta)

• MomentumMarkets in commodities are highly cyclical. The economic cycle produces sustained divergences between supply and demand dynamics resulting in persistent trending behaviour of commodity prices during the up- and downswing phases of cycles

• ValueValue strategies are intended to take advantage of situations of scarcity or excess of supply relative to demand. To that end, the inverse relationship between inventories and prices is exploited

• Carry / SeasonalityGiven the pronounced influence of weather and seasons on the demand and supply of energy and agricultural commodities strong seasonal elements are evident in their price dynamics. By arbitraging the term structure investors can take advantage and profit from this phenomenon

• VolatilityVolatility premium strategies aim to earn the premium at which implied volatility is traded in option markets relative to realized volatility. In doing so they accept the risk of unanticipated peaks in realized market volatility

• Blending market-neutral commodity risk premium strategies with a core commodity beta portfolio presents a compelling value proposition considering the marginal degree of correlation with diversified commodity beta strategies such as the Bloomberg or Picard Angst Commodity Index (PACI)

• Furthermore, consistently uncorrelated behaviour relative to global benchmarks of traditional asset classes such as equities (as represented by the MSCI World Developed Markets Index) and bonds (as represented by the JP Morgan Global Aggregate Bond Index) in combination with an attractive risk-return profile naturally predisposes such systematic strategies to be used as portfolio diversifiers and return enhancer in its own right across asset classes

Summary

October 16 Picard Angst AG

• From a price perspective commodities markets may be near a cycle low. Market prices of the majority of commodities have declined deep into marginal production cost curves. Given the tepid global growth outlook, however, any sustained recovery will be driven initially by rationalization of excess supply

• The recent cycle downswing is not out of line with the historical record. Factors such as diversification potential and inflation sensitivity that originally prompted pension funds to include commodities in their strategic asset allocation retain validity

• The overwhelming majority of institutional asset invested in commodities continue to track standard benchmarks such as the Bloomberg or S&P GSCI Commodity indexes or enhanced variations thereof despite obvious deficiencies in their construction

• In order to mitigate the pronounced return cyclicality inherent to the asset class, institutional investors are well-advised to look beyond pure beta investment solutions to commodities and consider adding exposure to targeted alternative risk premia offered by the asset class
