This paper investigates a novel optimization problem motivated by sparse, sustainable and stable portfolio selection. The existing benchmark portfolio via the Dantzig type optimization is used to construct a sparse, sustainable and stable portfolio. Based on the formulations, this paper proposes two portfolio selection methods, west and north portfolio selection, and investigates their empirical properties. Numerical results presented for 12 datasets and various simulated data show that the west selection can reduce risk, and the north selection may outperform the benchmark as to risk-adjusted returns (based on, e.g., information ratio and Sharpe ratio).

Portfolio selection has attracted increasing attention in machine learning and AI communities recently. Existing portfolio selection using recurrent reinforcement learning (RRL) heavily relies on single asset trading system to heuristically obtain the portfolio weights. In this paper, we propose a novel method, the direct portfolio selection using recurrent reinforcement learning (DPS-RRL), to select portfolios directly. Instead of trading single asset one by one to obtain portfolio weights, our method learns to quantify the asset allocation weight directly via optimizing the Sharpe ratio of financial portfolios. We empirically demonstrate the effectiveness of our method, which is able to outperform state-of-the-art portfolio selection methods.

China has been attracting overseas real estate developers (OREDs) with its expanding real estate market since the adoption of the Open Door Policy. This attractiveness has been enhanced by China's accession to the World Trade Organization and the Closer Economic Partnership Arrangement and is likely to remain for the foreseeable future. However, OREDs to conduct developments in China which adopts a socialist market-oriented approach is not without difficulties. The study has developed a SWOT dimensional analysis technique which is able to integrate the strengths and weaknesses of OREDs and also the opportunities and threats found in the market for formulating their (s)trategic plans and market positions. Apart from proposing a holistic model for OREDs’ strategic planning, the findings also suggested that OREDs in Guangzhou are in general strong in management and financial capacity but weak in understanding the market conditions. Building up a localized management team which understands the market and has good connection with local officials and business peoplė is of prime concerns. Santrauka Patvirtinus atvirų durų politiką (angl. Open Door Policy), besiplečianti Kinijos nekilnojamojo turto rinka pritraukia vis daugiau užsienio nekilnojamojo turto plėtotojų (angl. OREDs). Toks jos patrauklumas išaugo Kinijai įstojus į PPO ir įgijus glaudesnės ekonominės partnerystės statusą (angl. Closer Economic Partnership Arrangement), be to, numatoma, kad artimiausiu metu jis niekur neišnyks. Tačiau užsienio nekilnojamojo turto plėtotojai, vykdantys plėtrą Kinijoje, kurioje taikomas socialistinis, į rinką orientuotas požiūris, susiduria su sunkumais. Tyrimo metu buvo sukurtas lyginamosios SSGG analizės metodas, leidžiantis integruoti užsienio nekilnojamojo turto plėtros specialistų stiprybes ir silpnybes bei aptiktas rinkoje galimybes ir grėsmes, kurios padės suformuluoti strateginius jų planus ir rinkos pozicijas. Be pasiūlyto holistinio modelio užsienio nekilnojamojo turto plėtotojų strateginiam planavimui, rezultatai rodo, kad užsienio nekilnojamojo turto plėtotojai Guangžou užima stiprią poziciją finansų ir valdymo srityje, tačiau silpnai orientuojasi rinkos sąlygomis. Būtina laikytis esminės koncepcijos – sukurti lokalią valdymo komandą, gerai besiorientuojančią rinkoje ir palaikančią gerus santykius su vietos valdžia ir verslininkais.

Alpha Titanium

The in situ experimentation technique in HVEM seems to be particularly suitable to clarify the processes involved in recrystallization. The material under investigation was unidirectionally cold-rolled titanium of commercial purity. The problem was approached in two different ways. The three-dimensional analysis of textures was used to describe the texture evolution during the primary recrystallization. Observations of bulk-annealed specimens or thin foils annealed in the microscope were also made in order to provide information concerning the mechanisms involved in the formation of new grains. In contrast to the already published work on titanium, this investigation takes into consideration different values of the cold-work ratio, the temperature and the annealing time.Two different models are commonly used to explain the recrystallization textures i.e. the selective grain growth model (Beck) or the oriented nucleation model (Burgers). The three-dimensional analysis of both the rolling and recrystallization textures was performed to identify the mechanismsl involved in the recrystallization of titanium.
