90% of Fund of Hedge Funds construct their portfolios based on mean variance optimization (EDHEC, Lille-Nice).

1. Up- and downside risk are not distinguished. Discrimination of volatility destroys upside potential.

2. Capture of extreme events is very limited (fat tails and asymmetry), although their occurrance from time to time is a stylized fact

i.e. asymmetry (skewness) and "fat tails" (excess kurtosis) are not taken into account:

a) Strategy or asset class specific skewness and kurtosis.

b) Cross-asset class specific co-skewness and co-kurtosis.

c) No capability to account comprehensively and non-discretionarily for all central and co-moments up to order 4.

JP Omega Ltd.

Those flaws were motivating the development of Johnson Omega introduced subsequently as alternative measures such as the Sortino ratio and e.g. expected tail loss solved only parts of the weaknesses or even introduced new issues.

II. Characteristic Moments of Assets and Asset Classes

Event Driven: Again very low volatility in line with large tail fatness towards the downside.

1.

Equity Hedge: Still insificant skewness, but significant excess kurtosis. Thus outliers may happen towards upside and downside.

Emerging Markets: High risk in traditional sense is amplified by fat tail towards the downside, due to significant negative skewness and excess kurtosis.

FOF: Conservative is pretending to be low risk due to a low volatility. In fact high risk due to significant and substantial negative asymmetry and tail fatness towards the downside.

6.

Macro: Not low volatility, but extremely favorable fat tail properties. Significant positive skewness joint with moderate positive excess kurtosis. Usually positive / neutral impact in market dislocations. Further, Macro possesses positive co-moment properties.

Relative Value: As ED low volatility, jointly with significant negative skewness and significant excess kurtosis. Thus, large fat tail to downside, which has to be taken into account for a risk analysis and portfolio construction.

Table of HFRI Hedge Fund Strategies: Stable Skewness and Kurtosis CharacteristicsAll strategies show similar patterns as already seen in Risk article from 2005. Remain stable over decades.Typical and significant "tail fatness" and asymmetry characteristics were exploitable already before LTCM and Lehman collapse.

1. Extreme events, 9-11, Lehman collapse, LTCM / Russia crisis are not reflected in asset volatility (those few days are completely diluted).

2. Extreme event co-movement, such as correlation to 1 phenomena in stocks are not captured in correlation (also completely diluted).

3. Higher central and co-moments are only weakly diluted over time and remain visible for decades due to impact of 3rd and 4th order.

4. Higher moments jointly with variance and co-variance are capable to account for risk appropriately as information remains visible.

5. Higher moments allow to construct portfolios where diversification holds when needed as rare events are taken under consideration with appropriate likelihoods.

Yes, due to low dilution over time

Some Comments on "Rare Events":

The Johnson distribution framework introduced subsequently will fulfill all these criteria and allows to derive a perfomance measure, which is able to account appropriately for all possible outcomes, by attributing reasonable probabilities in calm, boom or bust markets.

Trend / Momentum / Herding behavior (e.g. ARIMA, Factor Models, proprietary forecasting)

Market sentiment, Asset characteristic, Volatility clustering etc. (historic standard deviation or GARCH models)

Asset constituents interaction over the long term (historic long-term correlation or GARCH type models)

Asymmetry, which means the characteristic direction of outliers in case of extreme events.

Downside- or Upside co-movements (or neutral) in extreme market situations.

Tail Fatness, which is the charateristic magnitute of outliers in case of extreme events.

Mutual amplification or mitigation of returns in extreme market movements through asset interaction.

1. Strong bias towards low volatility strategies (ow risk in mean-variance framework). 1. Remains in the center of Put and Call spectra. No bias, e.g. towards low/high volatility.

2. Substantial negative Skewness and excess Kurtosis, i.e. "fat tail" to downside. 2. Moderate negative Skew, widely eliminated excess Kurtosis, i.e. no downside fat-tail.

3. High Sharpe Ratio. 3. Lower, but more realistic Sharpe Ratio (no 4-5 StDev. events to be expected frequently).

4. Both Johnson Call and Johnson Put with equal and low amounts (low upside / low downside) 4. Johnson Call clearly more precious than Johnson Put, i.e. increased Johnson Omega ratio.

Volatility

Assume a portfolio has the following mean variance characteristics (monthly excess returns vs riskfree):

1. Hurdle

2. Mean 2. Johnson Omega is monotonously increasing with respect to skewness.

3. Volatility

Assuming a Riskfree Rate of 3% p.a. this would result in an annualized Sharpe ratio of 0.64.

This can be understood by looking at the (logarithmic) CDF chart:

JP Omega Ltd.

3.

4.

The complexity of moment interaction demanding for a rigorous treatment of upside versus downside becomes apparent from the finding that a large negative skewness and high kurtosis is on isokline to Normal distribution (skewness=0 and kurtosis=3). For a better understanding the call and put prices are considered:

Optimum with respect to skewness and kurtosis, potentially without sacrificing mean-variance optimum.

Johnson Omega can distinguish portfolios looking identical for Sharpe

Defined in the entire Johnson distributions support, i.e. kurtosis>1+skewness2. The blue enveloping parabola curve in the contourplot limits this feasible region (it can be shown that no distributions below that curve are feasible at all, please refer to Kendall & Ord, Advanced Statistic - Distribution Theory).

0,8%

Not necessarily the portfolio with lowest volatility is least risky. Risk adjusted Johnson Omega performance measure can be higher just subject to favorable skewness and kurtosis properties.

5.

Returns of below hurdle are expected to happen in around 33% of the cases for the negatively skewed distribution (due to the mode greater than the mean). In contrast, when assuming Gauss distribution 0% is expected to be undershoot in 50% of the cases. The poor tail properties of the negatively skewed distribution comes only when returns below -5% are considered. Downside is not the same as tails. Therefore one may look at MaxGainLoss Ratio.

Interpretation & Remarks:a) Marginal attribution w.r.t. equally weighted portfolio shows impact of increase of particular strategy to portfolio moments, JP Call,JP Put and JP Omega at first iteration. b) Proprietary closed form solutions of EMA, i.e. gradients and Greeks available.

i) HFRI Event DrivenPositive attribution to return, however, incease of volatility. Worsen tail fatness and asymmetry towards downside fat tail.-> Increase of both call and put (mitigated through increase of mean). Overall, slight increase of Omega ratio.

ii) HFRI Equity HedgeNegative attribution to Mean, further increase of volatility. However, positive tail properties (increases skewness and reduces kurtosis). Bending distribution towards outliers toupside rather than downside. -> Decrease of call and increase of put (mitigated through favorible tail properties). Overall, decreasing impact on Omega ratio.

iii) HFRI Emerging Markets

-> Substantial decrease of call and massive increase of put (only weakly mitigated through favorable correlation-diversification impact). Overall, highly bad impact on Omega ratio.iv) HFRI Macro

Positive attribution to return, reduction of volatility. Thus, improvement in traditional sense. Further, massively reduces tail fatness and also bends asymmetry towards upside.-> Increase of both call and put (mitigated through increase of mean). Overall, slight increase of Omega ratio.

v) HFRI Relative Value

-> Increase of call and reduction of put (worsening of tail is compensated by reduced volatility and substantial increase of expected mean). Overall, clear increase of Omega ratio.

JP Omega Ltd.

Highly negative attribution to Mean, and slight increase of volatility. However, very poor tail properties (makes skewness more negative and substantially increases kurtosis). Bending distribution towards a "big fat tail".

Highest attribution to return and favorable impact portfolio volatility. Excellent diversifier in the mean variance space. However, substantially increased tail fatness & bending asymmetry towards higher downside risk. Contrary picture to Macro: Both have mitigating influence on volatility but opposite impact on tail fatness and direction.

VIII. Johnson Omega optimization transparency through Expected Marginal Attribution (EMA) analysis

2. Interpretation of Expected Marginal Attribution:

1. EMA of HFRI Strategies ax ante Lehman Collapse (31-Aug-2008)

HFRI Equity Hedge-0,16%0,10%0,87

EMA to JP Omega indicates short Emerging Market as it reduces call and incrices put.

EMA to portfolio options (joined impact of portfolio moments): e.g. adding to Emerging Markets reduces upside (call) and reduces downside (put), by 1% x (-0.85%)=-0.85bps and

EMA to portfolio moments. E.g. adding 1% to Macro (while reducing the remaining strategies by 0,25% each) causes an increase of portfolio skewness by 1% x 1.77=0.017. Therefore adding to Macro bends the distribution from negative to positive skewness. Tail fatness massively reduced.

4. Decision which portfolio is superior is implied by CDF

At each level of confidence the Johnson Omega optimized has a higher minimum expected return than the Sharpe optimal portfolio, i.e. Johnson Omega 1st order stochastically dominates Sharpe Portfolio.

Johnson Omega portfolio may be superior to Sharpe optimal portfolio for each rational investor (irrespective whether risk averse, or risk tolerant, irrespective of his utility function).

-3,1%0,4%8,5%

Johnson Omega portfolios are potentiall superior as they can comprehensively and non-discretionarily account for asymmetry (skew) and tail-fatness (kurtosis) of the return distribution.

* Potentially insignificant and 'noisy' or instable moments of order 5 and higher included. * Requires Market Capitalization and discretionary views.

* Higher portfolio turnover and transaction cost. * Based on mean-variance assumption and quadratic utility.

* * This is basically a mean-variance optimization

* Asymmetry and tail fatness of specific assets not taken into account

*

* This is just a degree Fahrenheit-Celsius like affince transformation:

* Requires the discretionary choice of a conficence level

* Yields portfolios with inferior risk-adjusted returns as risk not taken into account.

* Throughout all backtests larger maximum drawdowns (available upon request).

*

* Ignores the widely accepted rule to beware of "grabbing a falling knife".

* Yields the same ranking as Omega.

* Does not take trend- a well established stylized fact - into account.

* Descretionary moment weighting required (for mean, variance, skewness and kurtosis) *

**

* Outcomes very sensitive to discretionary weightings of moments.

XI. Review of Johnson Omega development

1. History of Omega

4. Practical Experience

* 2003 in European Alternative Multimanagement Survey: "… 82 of responders consider Shar and only 4% calculate an Omega ratio, despite of the fact that the latter is more appropriate for the alternative universe".

* 2004 in 'Fund of Hedge Fund Reporting': "… 53 of them (Fund of Hedge Funds) consider Omega to be an important or very important indicator…"

* 2005 in 'Fund of Hedge Fund Reporting': "… the Omega ratio is now required by 57% of fund managers and 48% of investors…"

*

*

*

*

*

* Successfully applied in hedge fund industry and tested for hedge fund indices, cross asset class and equty sector indices.

* A US pension fund with investments in bond & stocks, currently managed by Barclays was outperformed at high confidence level with respect to absolute and risk adjusted returns.

* Many presentations to institutional clients have received positive feedback.

* Explicit Johnson-Omega representations are undisclosed todate and private knowledge.

JP Omega Ltd.

2005 in Editorial by Prof. Lionel Martini: "… Passow (2004) suggests modelling higher order moments applying the Johnson cumulated densities to calculate the so-called Johnson-Omega. The advantage of Johnson-Omega is to extract persistent information from track record and exploit the persistence of higher moments (i.e. up to 4). It therefore overcomes the instabilities with non-parametric approaches to Omega and allows for more reliable portfolios".

2007 in 'Funds of Hedge Fund Reporting Survey': "… However, it is worth noting that new performance measures, which are better suited for alternative investments, are gaining acceptance, demonstrating the interest of market participants in rationalising the performance evaluation and attribution process. Indeed, the Omega ratio is already considered to be important to very important by 57% of fund managers and 48% of investors.

XII. Some Citations of Omega and Johnson Omega from Academia & Practice

1. EDHEC Business School (Lille-Nice)

Winton Capital Management (AuM >USD12Bn) in an application to CTA performance (2003): "… we conclude that, owing to ist superior handling of the higher moments of returns distributions, Omega provides a superior risk/return measure of the more commonly used mean/variance metrics....".

Mausser, Saunders & Seco in Risk Magazine 'Cutting Edge' (2006): "… The parametric approach to optimizing Omega discussed in Passow (2005) offers an interesting alternative to the (non-parametric) approach taken in this article…".

Riskmetrics Group (2007): "… The Omega ratio is a new measure of performance. It overcomes the inadequacy of many performance measures when applied to investments that do not have normally distributed returns by taking the entire distribution into account..."

XIII. Conclusion

Accounts for economically stylized facts related to Mean, (Co-)Variance, (Co-)Skewness and (Co-)Kurtosis of (between) assets.1.

2. Able to account for each combination of asymmetry (skewness) and tail fatness (kurtosis).

Extends the theory of Markowitz (Modern Portfolio Theory) to call-put-space accounting for skewness and kurtosis.

Provides superior diversification, which holds when needed, by accounting for (only weakly diluted) skewness and kurtosis.

Uses proprietary Johnson Call and Johnson Put prices (and Greeks) generalizing Black-Scholes-Merton to any asymmetry and tail fatness.

Ignores and does not require other ("noisy") estimates and calibrations besides the input of stylized economic facts.

Avoides data-mining as non-discretionary because first 4 moments are uniquely and comprehensively merged.

Generates potentially 1st order stochastic dominating portfolios (preferable by each rational investor, irrespective of his utility function)

Allows to naturally include Riskfree asset in optimization for the non-discretionar determination of leverage.

15. Allows to be applied to all kind of portfolios, e.g. Long-Only, Long-Bias, Long-Short, etc.

Consistent with traditional performance ratios such as Sharpe, Sortino, Treynor and Information Ratio.

Links intuitive and naturally both Nobel Prize awarded theories through put-call-parity.

13.

Reduced model risk as Johnson Omega directly utilizes CDF. Idea is just bend & shift CDF to higher risk-adjusted, potentially 1st order SD returns.9.

18. Unified and consistent theory covering key disciplines: Portfolio Construction, Option Pricing and Risk Management.

14.

Allows higher upside potential as volatility not discriminated per se. Risk, i.e. Johnson Put price is just cost of insurance below hurdle.11.

12.

Naturally given hurdle (benchmark portfolio) may be modified for e.g. pension funds, which must generate guaranteed returns.

16. Allows to optimize fast and unique due to availability of closed form solution of performance measure.

17. Tested practically on various universes (traditional & alternative assets) showing significant absolute and risk-adjusted Outperformance.
