Der volle Inhalt der QuelleThe purpose of this thesis is to provide solutions to problems of statistical estimation and optimal allocation of portfolio containing hedge funds. These problems are of different natures: optimization, segmentation, dependencies and others. The first part focus is to develop the theoretical problem of maximizing the Omega ratio and to determine the optimal shape of the portfolio payoff in the case of Gaussian distributions. The second part is mainly empirical; it is devoted to the analysis of different optimal portfolios containing hedge funds and obtained by using four criteria: Sharpe, RoVaR, Omega and RoCVaR. One linked problem to optimization is developed. This is the unsupervised classification of hedge funds based on their past return series. In the same empirical part, structures dependency between different assets are explored by developing, in the tri-varied case, an adequacy tests, such as Cramer Von Mises and Kolmogorov Smirnov

Der volle Inhalt der QuelleThe purpose of this work is to understand the interactions between equity market liquidity and monetary policy on the one band, and to study the impact of market liquidity on optimal portfolio allocation on the other. In the first chapter, we examine the interactions between equity market liquidity and monetary policy. Our results show that the latter has no impact on market liquidity throughout the period. The latter significantly influences monetary policy uncertainty. Furthermore, we find that monetary policy has an asymmetric effect on market liquidity. ln the second chapter, we study the impact of market liquidity on portfolio allocation. The investor seeks to dynamically maximize bis expected utility under the constraint of the portfolio's instantaneous return. We determine the optimal allocation and consumption of the portfolio. The empirical results show that market liquidity significantly affects optimal allocation and consumption. ln the last chapter, we study how the simultaneous presence of liquid and imperfectly liquid assets can influence optimal portfolio allocation. Thus, we use the martingale method under the no arbitrage opportunities approach to solve the dynamic optimization program. We obtain an analytical solution for the demands. The investor will underinvest or overinvest in both assets, compared to the Merton model, depending on his risk aversion and the level of market liquidity

Der volle Inhalt der QuelleThe main objective of this present work is to reveal new contributions of options for the optimal welfare of the investors and the global efficiency of the financial system. In the presence of transaction costs and for volatile rates of return, the dynamic investment seems expensive or in defect underestimated. The strategy Buy and Hold allows reducing the consequences of this cost, but also increases the loss of capital. In this work, we show that the introduction of options improves and stabilizes the incomes of certain policies in particular, assets optimal allocation. Our methodology bases on the principle of replication adopted by Black and Scholes (1973). In the context of Buy and Hold contained options, the replication of the standard allocation means optimizing two functions objectives: minimization of MSE (Mean Squared Errors) and minimization of WMSE (Weighted Mean Squared Errors). The selected portfolio Buy and Hold are those having a cost of replication lower than the costs forecasted by the dynamic investment. The tests on the efficiency of the replicated strategies concern, at first time, the optimal placement of an averted risk investor on horizon of 10 years. The options are supposed OTC, the settlement prices are approximate by a multiperiodic binomial tree. The first results bring to light the existence of several Buy and Hold containing options, more successful than the allocation based by Samuelson and Merton (1969). Supposing that the costs of transaction are proportional in the volumes of financial assets, the space of dynamic revision of portfolio is been defined by the presence of a region of non-activity. The analysis of the ex-ante management of profit-cost, allowed us to preview manager funds activities and their specific costs. The link of these management costs with the costs of replication supports the conception of a whole block of replicas portfolios more successful than the dynamic allocation of funds. The optimal behaviour of the economic agent, the diversification of capital in this particular case, is a function of the number, the type, as well as its position on the options. To fix his decision, he chooses, since the negotiation with his banker, one of the strategies maximizing his preferences, independently of the imperfections of the market. At the second time, the empirical evidence poses the case of a short-term investment, on the CAC 40 index and the call options of terms 6 months, launched on MONEP. The results prove the efficiency of the portfolio allowing the investor to have a terminal quasi-equal wealth in that waited by the standard allocation. A certain analogy was contested between the replicas strategies and certain mechanisms of covered products based on option and financial support, in this particular case the guaranteed capital, Covered Call writing and Protected Put
Graewe, Paulwin. „Optimal liquidation problems and HJB equations with singular terminal condition“. Doctoral thesis, Humboldt-Universität zu Berlin, Mathematisch-Naturwissenschaftliche Fakultät, 2017. http://dx.doi.org/10.18452/17776.
Der volle Inhalt der QuelleWe study stochastic optimal control problems arising in the framework of optimal portfolio liquidation under limited liquidity. Our framework is flexible enough to allow for Markovian and non-Markovian impact functions and for simultaneous trading in primary venues and dark pools. The key characteristic of portfolio liquidation models is the singular terminal condition of the value function that is induced by the liquidation constraint. For linear-quadratic models, the standard ansatz reduces the HJB equation for the value to a (system of) partial differential equation(s), backward stochastic differential equation(s) or backward stochastic partial differential equation(s) with singular terminal condition, depending on the choice of the cost coefficients. We establish novel existence, uniqueness and regularity results for (BS)PDEs with singular terminal conditions arising in models of optimal portfolio liquidation, prove that the respective value functions can indeed be described by a (BS)PDE, and give the optimal trading strategies in feedback form. For Markovian and non-Markovian impact models we establish a novel approach based on the precise asymptotics of the value function at the terminal time. For purely Markovian liquidation problems this allows us to establish the existence smooth solutions to singular PDEs. For a class mixed Markovian/non-Markovian models we characterize the HJB equation in terms of a singular BSPDE for which we establish existence and uniqueness of a solution using a stochastic penalization method.
Kratz, Peter. „Optimal liquidation in dark pools in discrete and continuous time“. Doctoral thesis, Humboldt-Universität zu Berlin, Mathematisch-Naturwissenschaftliche Fakultät II, 2011. http://dx.doi.org/10.18452/16367.
Der volle Inhalt der QuelleWe study optimal trading strategies of a risk-averse investor who has to liquidate a portfolio within a finite time horizon [0,T]. The investor has the option to trade at a traditional exchange (the "primary venue") which yields price impact and to place orders in a dark pool. The liquidity in dark pools is not openly displayed and dark pools do not contribute to the price formation process: orders are executed at the price of the primary venue. Hence, they have no price impact, but their execution is uncertain. The investor thus faces the trade-off between the price impact costs at the primary venue and the indirect costs resulting from the execution uncertainty in the dark pool. In a discrete-time market model we consider a cost functional which incorporates the expected price impact costs and market risk costs. For linear price impact, it is linear-quadratic and we obtain a recursion for the optimal trading strategy. For single asset liquidation, the investor trades out of her position at the primary venue, with the remainder being placed in the dark pool. For multi asset liquidation this is not optimal because of the correlation of the assets. In the presence of adverse selection in the one dimensional setting the dark pool is less attractive. In continuous time the liquidation constraint implies a singularity of the value function at the terminal time T. In the linear-quadratic case without adverse selection it is described by the limit of a sequence of solutions of a matrix differential equation. By means of a matrix inequality we obtain bounds of these solutions, the existence of the limit and a verification argument via HJB equation. In the presence of adverse selection the value function has an unusual structure, which we obtain via extensive heuristic considerations: it is a "quasi-polynomial" whose coefficients depend on the asset position in a non-trivial way. We characterize the value function semi-explicitly and carry out a verification argument.
Dieye, Abdoulaye Ndiaye. „Asset Return Determinants : risk Factors, Asymmetry and Horizon consideration“. Thesis, Lyon, 2019. http://www.theses.fr/2019LYSE2070.
Der volle Inhalt der QuelleThe determinants of asset returns remain an active research topic in the financial literature. This thesis focuses on the role of certain risk factors, of the asymmetry of the distribution of returns and of the investment horizon as determinants of asset returns. We first demonstrate that the size effect can be considered partially due to specific industries that are considered statistically relevant to explain the performance of the portfolios of small (big) firms and we study the empirical implications of this finding in terms of asset pricing. We then consider the relationship between the market and the main risk factors proposed in the literature – including the factor SMB that explicitly accounts for the size effect – and point out that the considered factors can be partially explained by a non-linear relation with the market factor. In addition, we show that exploiting the non-linear relationship between the market and these risk factors can be profitable in terms of investmentstrategies. The last part of this thesis focuses on the issue of time diversification and analyses the impact of the horizon on the properties of the compounded return distributions to show that the compounding effect is the main reason for the shapeof the long-term return distributions. We then shed new light on the divergences of opinion expressed in the literature regarding long-term investment strategies
