Finns det möjlighet till arbitrage på VINX30 aktieindexoptioner? : en empirisk undersökning

Lindström, Thomas, Stenkvist, Cecilia January 2008 (has links)
<p>Optioner är ett instrument som investerare kan använda för att spekulera i framtida upp-eller nedgångar på olika tillgångar. Om dessa optioner är felprissatta finns det möjlighet att göra riskfria vinster med hjälp av Stolls köp-säljparitet. Tidigare studier visar att marknaden inte alltid är effektiv i sin prissättning av aktieindexoptioner och att det därigenom finns möjlighet till arbitrage. Denna studie undersöker huruvida marknaden är effektiv i sin prissättning av VINX30 aktieindexoptioner, d.v.s. <em>finns det möjlighet till arbitrag på VINX30 aktieindexoptioner?</em></p> / <p>Options are an instrument which investors can use to speculate in future pricemovements on different assets. If these options are misspriced there are an opportunity to get riskfree profit by using Stolls put-call parity. Earlier research shows that the market sometimes is inefficient when pricing stock index options allowing arbitrage. This study investigate whether the market is efficient in the pricing of VINX30 stock index options, i.e.<em> are there arbitrage opportunities on VINX30 stock index options?</em></p>

Code generation and simulation of an automatic, flexible QC-LDPC hardware decoder

Von Leipzig, Mirko 03 1900 (has links)
Thesis (MEng)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Iterative error correcting codes such as LDPC codes have become prominent in modern forward error correction systems. A particular subclass of LDPC codes known as quasicyclic LDPC codes has been incorporated in numerous high speed wireless communication and video broadcasting standards. These standards feature multiple codes with varying codeword lengths and code rates and require a high throughput. Flexible hardware that is capable of decoding multiple quasi-cyclic LDPC codes is therefore desirable. This thesis investigates binary quasi-cyclic LDPC codes and designs a generic, flexible VHDL decoder. The decoder is further enhanced to automatically select the most likely decoder based on the initial a posterior probability of the parity-check equation syndromes. A software system is developed that generates hardware code for such a decoder based on a small user specification. The system is extended to provide performance simulations for this generated decoder. / AFRIKAANSE OPSOMMING: Iteratiewe foutkorreksiekodes soos LDPC-kodes word wyd gebruik in moderne voorwaartse foutkorreksiestelsels. ’n Subklas van LDPC-kodes, bekend as kwasisikliese LDPC-kodes, word in verskeie hoëspoed-kommunikasie- en video-uitsaaistelselstandaarde gebruik. Hierdie standaarde inkorporeer verskeie kodes van wisselende lengtes en kodetempos, en vereis hoë deurset. Buigsame apparatuur, wat die vermoë het om ’n verskeidenheid kwasisikliese LDPC-kodes te dekodeer, is gevolglik van belang. Hierdie tesis ondersoek binêre kwasisikliese LDPC-kodes, en ontwerp ’n generiese, buigsame VHDL-dekodeerder. Die dekodeerder word verder verbeter om outomaties die mees waarskynlike dekodeerder te selekteer, gebaseer op die aanvanklike a posteriori-waarskynlikheid van die pariteitstoetsvergelykings se sindrome. ’n Programmatuurstelsel word ontwikkel wat die fermware-kode vir so ’n dekodeerder genereer, gebaseer op ’n beknopte gebruikerspesifikasie. Die stelsel word uitgebrei om werksverrigting te simuleer vir die gegenereerde dekodeerder.

[en] PROFITABILITY CHECK OF CARRY TRADE OPERATION BETWEEN REAL AND DOLLAR (2005 A 2016) / [pt] VERIFICAÇÃO DA LUCRATIVIDADE DA OPERAÇÃO DE CARRY TRADE ENTRE O REAL E O DÓLAR (2005 A 2016)

ANELISE PALMIER BORGES DE ALMEIDA 29 November 2018 (has links)
[pt] O presente trabalho visa verificar a operação de carry trade. A lucratividade desta operação é observada quando a diferença de taxa de juros entre os dois países em análise é maior que a variação cambial do período. A verificação da operação, conforme literatura do tema, é realizada através do modelo de paridade descoberta de taxa de juros (PDTJ). A rejeição do modelo, vista através de regressão, possibilita a aceitação da lucratividade da operação. Este estudo, portanto, analisa esta operação entre o Brasil, país de alta taxa de juros e Estados Unidos, país de baixa taxa de juros. Ademais, o estudo visa analisar a operação em um momento de instabilidade econômica, período de 2005 a 2016, no qual consta a crise de 2008 que impactou fortemente as duas economias. / [en] The present work aims to check the carry trade operation. The profitability of this operation is observed when the interest rate difference between the two countries under analysis is greater than the exchange variation for the same period. The literature of carry trade is verified through the uncovered interest rate parity model (UIP). Rejection of the model, performed through regression, makes it possible to accept the profitability of the operation. This study, therefore, analyzes this operation between Brazil, a country with high interest rates and the United States, a country with low interest rates. In addition, the study aims to analyze the operation in a time of economic instability, from 2005 to2016, which includes the crisis of 2008 that strongly impacted the two economies.

PARITY VIOLATION IN THE HADRONIC WEAK INTERACTION

January 2012 (has links)
abstract: This thesis deals with the first measurements done with a cold neutron beam at the Spallation Neutron Source at Oak Ridge National Laboratory. The experimental technique consisted of capturing polarized cold neutrons by nuclei to measure parity-violation in the angular distribution of the gamma rays following neutron capture. The measurements presented here for the nuclei Chlorine ( 35Cl) and Aluminum ( 27Al ) are part of a program with the ultimate goal of measuring the asymmetry in the angular distribution of gamma rays emitted in the capture of neutrons on protons, with a precision better than 10-8, in order to extract the weak hadronic coupling constant due to pion exchange interaction with isospin change equal with one ( h&pi; 1). Based on theoretical calculations asymmetry in the angular distribution of the gamma rays from neutron capture on protons has an estimated size of 5&middot;10-8. This implies that the Al parity violation asymmetry and its uncertainty have to be known with a precision smaller than 4&middot;10-8. The proton target is liquid Hydrogen (H2) contained in an Aluminum vessel. Results are presented for parity violation and parity-conserving asymmetries in Chlorine and Aluminum. The systematic and statistical uncertainties in the calculation of the parity-violating and parity-conserving asymmetries are discussed. / Dissertation/Thesis / Ph.D. Physics 2012

Cohort fertility decline in low fertility countries: Decomposition using parity progression ratios

Zeman, Krystof, Beaujouan, Eva, Brzozowska, Zuzanna, Sobotka, Tomás 22 January 2018 (has links) (PDF)
BACKGROUND: The long-term decline in cohort fertility in highly developed countries has been widely documented. However, no systematic analysis has investigated which parity contributed most to the fertility decline to low and very low levels. Objective: We examine how the contribution of changing parity progression ratios varied across cohorts, countries, and broader regions in Europe, North America, Australia, and East Asia. We pay special attention to countries that reached very low completed cohort fertility, below 1.75 children per woman. Methods: Using population censuses and large-scale surveys for 32 low fertility countries, we decompose the change in completed cohort fertility among women born between 1940 and 1970. The decomposition method takes into account the sequential nature of childbearing as a chain of transitions from lower to higher parities. Results: Among women born between 1940 and 1955, the fertility decline was mostly driven by reductions in the progression ratios to third and higher-order births. By contrast, among women born between 1955 and 1970, changes in fertility showed distinct regional patterns: In Central and Eastern Europe they were fuelled by falling second-birth rates, whereas in the German-speaking countries, Southern Europe, and East Asia decreases in first-birth rates played the major role. Conclusions: Pathways to low and very low fertility show distinct geographical patterns, which reflect the diversity of the cultural, socioeconomic, and institutional settings of low fertility countries. Contribution: Our study highlights the importance of analysing parity-specific components of fertility in order to understand fertility change and variation. We demonstrate that similar low levels of completed cohort fertility can result from different combinations of parity-specific fertility rates.

Otimização de portfólios de investimento : a estratégia de paridade de risco no cenário brasileiro

Souza, Pierre Oberson de January 2015 (has links)
O presente trabalho busca dar início a estudos referentes ao modelo de otimização de portfolios de investimento denominado paridade de risco no cenário brasileiro. Neste trabalho, os índices setoriais da bolsa brasileira (Bovespa) foram utilizados como ativos e com os seus dados foram estimadas carteiras com os modelos de mínima variância, de pesos iguais e de paridade de risco. Verificou-se que no modelo de paridade de risco a forma de obtenção da matriz de covariância exerce pouca influência no resultado final, que é de carteiras com distribuição de pesos e volatilidades intermediárias com relação aos modelos de mínima variância e de pesos iguais. Estes resultados são condizentes com aqueles verificados na literatura que utilizam como base de dados os mercados europeus e americanos. / This paper seeks to initiate studies for the investment portfolios optimization model called risk parity in the Brazilian scene. In this work, the sector indexes of the Brazilian Stock Exchange (Bovespa) were used as assets and their data were used to estimate portfolios with models of minimum variance, of equal weight and of risk parity. It was found that in the risk parity model the form to obtain the covariance matrix has little influence on the final result, that is of a portfolio with weights and distribution of intermediate volatility in relation to the minimum variance models and equal weights. These results are consistent with those found in the literature using as database the European and American markets.

Reconhecimento e redistribuição : estratégias de empoderamento na relação entre mulheres e mídia

Tebaldi, Raquel January 2015 (has links)
Há quase 20 anos, a IV Conferência Mundial sobre a Mulher, realizada de 4 a 15 de setembro de 1995, em Pequim, reconheceu oficialmente como uma das principais áreas de preocupação para se atingir maior igualdade entre homens e mulheres a relação entre mulheres e os meios de comunicação. Dentro desse contexto, trilhando aproximadamente o espaço temporal da Conferência de Pequim até seu aniversário de 20 anos e partindo de um nível global de análise, o presente trabalho visa explorar as seguintes questões: por que a relação entre mulheres e mídia é considerada problemática? Como diferentes teorias feministas e de gênero entendem a relação entre mulheres e mídia e como essa problematização se transformou através das décadas para o feminismo acadêmico? Como é possível existir agência e mesmo empoderamento dentro da relação entre mulher e mídia e que estratégias podem ser empregadas nesse sentido pelo movimento feminista? O argumento central do presente trabalho é o de que a possibilidade de empoderamento na relação entre mulheres e mídia parece ser mais fértil quando se consideram estratégias não só de lutas por paridade dentro desse setor produtivo, mas também de conscientização do público em geral através de políticas educacionais. Assim, o trabalho busca analisar estratégias de empoderamento na área através da combinação de medidas de reconhecimento e redistribuição transformativas, como proposto por Nancy Fraser (1995). / Almost 20 years ago the Fourth World Conference on Women, held from September 4th to 15th in 1995, in Beijing, officially recognized as one of the main areas of concern to achieve greater equality between men and women the relation between women and media. Within this context, encompassing the 20 years after the Conference and within a global perspective, this paper seeks to explore the following research questions: why is the relation between women and media problematic? How do different feminist and gender theories understand the relation between women and the media and how this questioning has transformed over the decades within feminist academia? How can there be agency and even empowerment within the relation between women and the media and what are the strategies that can be employed in this sense by the feminist movement? The central argument of this paper is that the possibility of empowerment in the relationship between women and the media seems to be more fertile when considering strategies not only for fighting for parity within this productive sector, but also fighting for awareness of the general public through educational policies. Thus, this paper analyzes empowerment strategies in the area by combining transformative recognition and redistribution measures, as proposed by Nancy Fraser (1995).
