Momentum Trading in New York Stock Exchange (NYSE) Energy Stocks

This paper investigates whether the momentum effect exists in the NYSE energy sector. Momentum is defined as the strategy that buys (sells) these stocks that are best (worst) performers, over a pre-specified past period of time (the 'look-back' period), by constructing equally weighted portfolios. Different momentum strategies are obtained by changing the number of stocks included in these portfolios, as well as the look-back period. Next, their performance is compared against two benchmarks: the equally weighted portfolio consisting of most stocks in the NYSE energy index and the market portfolio, and the S&P500 index. The results indicate that the momentum effect is strongly present in the energy sector, and leads to highly profitable portfolios, improving the risk-reward measures and easily outperforming both benchmarks.

Trading the differences in expectations between the CDS and bond markets

This paper uses the framework developed by Vrugt (2010) to extract the recovery rate and term-structure of risk-neutral default probabilities implied in the cross-section of Portuguese sovereign bonds outstanding between March and August 2011. During this period the expectations on the recovery rate remain firmly anchored around 50 percent while the instantaneous default probability increases steadily from 6 to above 30 percent. These parameters are then used to calculate the fair-value of a 5-year and 10- year CDS contract. A credit-risk-neutral strategy is developed from the difference between the market price of a CDS of the same tenors and the fair-value calculated, yielding a sharpe ratio of 3.2

The Impact of a Corporate Name Change on Stock Price and Trading Volume of Canadian Companies

This thesis examines the impact of a corporate name change on stock price and trading volume of Canadian companies around the announcement date, the approval date, and the adoption date over the time period from 1997 to 2011. Name changes are classified into six categories: major and minor, structural and pure, diversified and focused, accompanied with a change in ticker symbol and without a change in ticker symbol, “Gold” name addition and deletion, and different reasons for name changes (e.g., merger and acquisition, change of structure, change of strategy, and better image). The thesis uses the standard event study methodology to perform abnormal return and trading volume analyses. In addition, regression analysis is employed to examine which type of a name change has the largest impact on cumulative abnormal returns. Sample stocks exhibit a significant positive abnormal return one-day prior to the approval day and one day after the adoption date. Around the approval date we observe significant abnormal returns for stocks with a structural name change. On the day after the adoption date we document abnormal returns for stocks with major, minor, structural, pure, focused, and ticker symbol name changes. If a merger or acquisition is the reason for a name change, companies tend to experience a significant positive abnormal return one-day before the approval date and on the adoption date. If a change of structure is the reason for a name change, companies exhibit a significant positive abnormal return on the approval date and a significant negative abnormal return on the adoption date. In case of a change of strategy as the reason for a name change, companies show a significant negative abnormal return around the approval date and a significant positive abnormal return around the adoption date.

Top trading with fixed tie-breaking in markets with indivisible goods

We study markets with indivisible goods where monetary compensations are not possible. Each individual is endowed with an object and a preference relation over all objects. When preferences are strict, Gale's top trading cycle algorithm finds the unique core allocation. When preferences are not necessarily strict, we use an exogenous profile of tie-breakers to resolve any ties in individuals' preferences and apply Gale's top trading cycle algorithm for the resulting profile of strict preferences. We provide a foundation of these simple extensions of Gale's top trading cycle algorithm from strict preferences to weak preferences. We show that Gale's top trading cycle algorithm with fixed tie-breaking is characterized by individual rationality, strategy-proofness, weak efficiency, non-bossiness, and consistency. Our result supports the common practice in applications to break ties in weak preferences using some fixed exogenous criteria and then to use a 'good and simple' rule for the resulting strict preferences. This reinforces the market-based approach even in the presence of indifferences because always competitive allocations are chosen.

Can profitable trading strategies be derived from investment best-sellers?

A glance along the finance shelves at any bookshop reveals a large number of books that seek to show readers how to ‘make a million’ or ‘beat the market’ with allegedly highly profitable equity trading strategies. This paper investigates whether useful trading strategies can be derived from popular books of investment strategy, with What Works on Wall Street by James P. O'Shaughnessy used as an example. Specifically, we test whether this strategy would have produced a similarly spectacular performance in the UK context as was demonstrated by the author for the US market. As part of our investigation, we highlight a general methodology for determining whether the observed superior performance of a trading rule could be attributed in part or in entirety to data mining. Overall, we find that the O'Shaughnessy rule performs reasonably well in the UK equity market, yielding higher returns than the FTSE All-Share Index, but lower returns than an equally weighted benchmark

A longitudinal study of carbon disclosure strategy: evidence from utility, energy and mining industries in the UK

The paper investigates how energy-intensive industries respond to the recent government-led carbon emission schemes through the content analysis of 306 annual and standalone reports of 25 UK listed companies from 2004 to 2012. This period of reporting captures the trend and development of corporate disclosures on carbon emissions after the launch of EU Emissions Trading Schemes (ETS) and Climate Change Act (CCA) 2008. It is found that in corresponding to strategic legitimacy theory, there is an increase in both the quality and quantity of carbon disclosures as a response to these initiatives. However, the change is gradual, which reflects in the achievement of peak disclosure period two years after the launch. It indicates that the new legislations have a lasting impact on the discourses rather than an immediate legitimacy threat from the perspective of institutional legitimacy theory. The results also show that carbon disclosures are an institutionalised practice as companies in the same industries and/or with same carbon trading account status appear to imitate and adopt the industry’s ‘best practice’ disclosure strategy to maintain legitimacy. The trend analysis suggests that the overall disclosure practice is still in its infant stage, especially in the reporting of quantitative and monetary items. The paper contributes to the social and environmental accounting literature by adopting both strategic and institutional view of legitimacy, which explains why carbon disclosures evolve in a specific way to meet the expectation of various stakeholders.

There is something about pairs trading

The process of pairs trading involves exhaustively matching and ranking pairwise stocks based on some prespecified measure of closeness; e.g., correlation, cointegration, sum-of-squared price difference. Pairs trading is popular for various reasons. It is simple to follow and execute. The pairwise portfolio can be nearly market-neutral, such that it does not require the comprehensive analysis of macroeconomic news. Since it is based on relative valuation, the actual worth of individual firms is not a pertinent consideration. The strategy is sufficiently flexible to accommodate various investment styles. Lastly, it does not evoke frequent intraday rebalancing, such that pairs trading can be automated to a certain extent and be cost-feasibly profitable. Despite its long history on Wall Street, pairs trading remains elusive in nature. The academic attention it attracts is modest compared to contrarian and momentum trading.

Negotiation strategy for mobile agent-based e-negotiation

Negotiation is a vital component of electronic trading. It is the key decision-making approach used to reach consensus between trading partners. Generally, the trading partners implement various negotiation strategies in an attempt to maximize their utilities. As negotiation strategies have impact on the outcomes of negotiation, it is imperative to have efficient negotiation strategies that truly maximize clients’ utilities. In this paper, we propose a multi-attribute mobile agent-based negotiation strategy that maximizes client’s utility. The strategy focuses on one-to-many bilateral negotiation. It considers different factors that have significant effect on the scheduling of various negotiation phases: offer collection, evaluation, negotiation, and bid settlement. The factors include offers expiry time, market search space, communication delays, processing queues, and transportation times. We reasoned about the correctness of the proposed negotiation strategy with respect to the existing negotiation strategies. The analysis showed that the proposed strategy boosts client’s utility, shortens negotiation time, and ensures adequate market search.

Estratégia de trading utilizando o modelo dinâmico de Nelson-Siegel

Esta pesquisa busca testar a eficácia de uma estratégia de arbitragem de taxas de juros no Brasil baseada na utilização do modelo de Nelson-Siegel dinâmico aplicada à curva de contratos futuros de taxa de juros de 1 dia da BM&FBovespa para o período compreendido entre 02 de janeiro de 2008 e 03 de dezembro de 2012. O trabalho adapta para o mercado brasileiro o modelo original proposto por Nelson e Siegel (1987), e algumas de suas extensões e interpretações, chegando a um dos modelos propostos por Diebold, Rudebusch e Aruoba (2006), no qual estimam os parâmetros do modelo de Nelson-Siegel em uma única etapa, colocando-o em formato de espaço de estados e utilizando o Filtro de Kalman para realizar a previsão dos fatores, assumindo que o comportamento dos mesmos é um VAR de ordem 1. Desta maneira, o modelo possui a vantagem de que todos os parâmetros são estimados simultaneamente, e os autores mostraram que este modelo possui bom poder preditivo. Os resultados da estratégia adotada foram animadores quando considerados para negociação apenas os 7 primeiros vencimentos abertos para negociação na BM&FBovespa, que possuem maturidade máxima próxima a 1 ano.

Gestão de risco cambial no ambiente corporativo : aplicação da análise de componentes principais para a gestão do risco cambial em Trading Companies brasileiras

O presente estudo busca analisar a adoção de técnicas de imunização de carteiras para a gestão dos hedges cambiais no ambiente corporativo de uma Trading Company, utilizando de forma pioneira a análise de componentes principais aplicada à curva cambial como uma alternativa aos modelos usualmente utilizados de hedge por exposição gerada (back-to-back) e duration hedge que mostram algumas deficiências em sua gestão. Para exemplificar a efetividade da estratégia de imunização foi gerada aleatoriamente uma carteira de exposição cambial com data base de 02/01/2013 composta por 200 transações com valores entre US$5 milhões e -US$10 milhões, para vencimentos também aleatórios entre 03/06/2013 e 01/12/2014 com vencimento no primeiro dia útil de cada mês. Os resultados da Análise de Componente Principais mostraram que para os períodos analisados de 1, 2 e 3 anos, os três primeiros componentes explicam respectivamente 97.17%, 97.90% e 97.53% da variabilidade da curva cambial. No que diz respeito à imunização da carteira, a estratégia que utiliza a metodologia de componentes principais mostrou-se altamente efetiva, quando comparadas à estratégia back-to-back, de forma a permitir a sua aplicabilidade no ambiente corporativo. A estratégia de hedge utilizando-se da Análise de Componentes Principais para 1, 2 e 3 anos e pelo Duration Hedge apresentaram uma efetividade de, respectivamente, 101.3%, 99.47%, 97.64% e 99.24% para o período analisado e uma amplitude na efetividade diária de 8.62%, 7.79%, 8.45% e 19.21% o que indica uma superioridade da estratégia em relação ao Duration Hedge. Os resultados obtidos nesse trabalho são de grande relevância para a gestão de risco corporativo no mercado local.

Germania: l’indomabile trading state

Basato su interviste con i principali attori tedeschi e su un’analisi della letteratura, l’articolo analizza lo sviluppo recente dell’economia tedesca e la strategia tedesca nell’affrontare la crisi dell’eurozona. La Germania è uno stato commerciale (trading state), la cui crescita è fortemente trainata dalle esportazioni. Fino agli anni novanta, rigidità istituzionali forti, nel sistema di relazioni industriali e nel sistema di protezione sociale, contribuivano a conciliare lo sviluppo delle esportazioni con una crescita armonica dei consumi interni, contribuendo cosi a ingabbiare la «tigre» tedesca. A partire dagli anni novanta, sia le relazioni industriali sia la protezione sociale sono state fortemente liberalizzate, stimolando ulteriormente la competitività estera e indebolendo i consumi interni. Il modello economico tedesco, cosi come è venuto profilandosi negli ultimi dieci anni, è alla base delle politiche di austerità che la Germania impone all’Europa. Tali politiche sono fortemente condivise dai partiti politici, dagli attori sociali e dall’opinione pubblica, e le probabilità che la strategia tedesca cambi sono minime.

The Crisis and Germany: The Trading State Unleashed

Based on interviews with the main German actors and on secondary sources, the article examines the recent development of the German political economy, and the German strategy vis-à-vis the Euro zone. Germany is a trading state whose economic growth is strongly export-led. Until the years 1990s, strong institutional rigidities, both in industrial relations and in the welfare state, contributed to reconcile export growth with household consumption, thus keeping the German “tiger” on a leash. From the early 1990s on, however, both industrial relations and social protections have been strongly liberalized, thus further stimulating external competitiveness and reducing the role of consumption in the German growth model. The unleashed trading state shapes the German response to the Euro crisis and the austerity policies that Germany imposes to Europe. These policies are strongly supported by political parties, social actors, and public opinion in Germany, and the likelihood that they change in the near future is minimal.

Toward an inclusive and a little bit ethical world trading system : listening to the voices of the people in LDCs

Many specialists in international trade have started saying that the era of a mega FTA is approaching. If the three poles of the global economy, namely East Asia, EU and the United States, form mega FTAs, most of the volume of global trade will be covered. That may be fine, but there will be many countries left out of the mega FTA, most of which will be the least developed countries (LDCs). Since the inception of the Doha Development Agenda (DDA) negotiations in 2001, the WTO and its member countries have tried to include LDCs in the world trading system through various means, including DFQF and AfT. Although these means have some positive impact on the economic development of LDCs, most of the LDCs will never feel comfortable with the current world trading system. To overcome the stalemate in the DDA and to create an inclusive world trading system, we need more commitment from both LDCs and non-LDCs. To surmount the prolonged stalemate in the DDA, we should understand how ordinary people in LDCs feel and think about the current world trading system. Those voices have seldom been listened to, even by the decision makers of their own countries. So as to understand the situation of the people in LDCs, IDE-JETRO carried out several research projects using macro, meso and micro approaches. For the micro level, we collected and analyzed statements from ordinary people concerning their opinions about the world trading system. The interviewees are ordinary people such as street vendors, farmers and factory workers. We asked about where they buy and sell daily necessities, their perception of imported goods, export promotion and free trade at large, etc. These ‘voices of the people’ surveys were conducted in Madagascar and Cambodia during 2013. Based on this research, and especially the findings from the ‘voices of the people’ surveys, we propose a ‘DDA-MDGs hybrid’ strategy to conclude DDA negotiations and develop a more inclusive and a little bit more ethical world trading system. Our proposal may be summarized in the following three points. (1) Aid for Trade (AfT) ver. 2 Currently AfT is mainly focused on coordinating several aid projects related to LDCs’ capacity building. However, this is inadequate; for the proposed ‘DDA-MDGs hybrid’, a super AfT is needed. The WTO, other development agencies and LDC governments will not only coordinate but also plan together aid projects for trade capacity building. AfT ver. 2 includes infrastructure projects either gran aid, ODA loans and private investment. This is in accordance with the post-MDGs argument which emphasizes the role of the private sector. (2) Ethical Attitude Reciprocity is a principle of multilateral agreement, and it has been a core promise since GATT. However, for designing an inclusive system, special and differential treatment (S&D) is still needed for disadvantaged members. To compromise full reciprocity and less than full reciprocity, an ethical attitude on the part of every member is needed in which every member refrains from insisting on the full rights and demands of its own country. As used herein, the term ‘ethical’ implies more consideration for LDCs, and it is almost identical to S&D but with a more positive attitude from developed countries (super S&D). (3) Collect Voices of the People In order to grasp the real situation of the people, the voices of the people on free trade will continue to be collected in other LDCs, and the findings and leanings will be fed back to the WTO negotiation space.
