Using futures contracts for corporate hedging: The problem of expiry and a possible solution

Companies using futures contracts for hedging purposes need to roll over their contracts if the maturity of their exposure exceeds that of the futures contracts. This entails basis risk that can reduce significantly the effectiveness of the hedge. In this paper an alternative form of futures contract is proposed. the contract never expires and can be used for long-term hedging without the need for rolling-over into a new contract. the contract is shown to be equivalent to a portfolio of conventional futures contracts of differing maturities. Its price is determined by arbitrage against the underlying asset.     

The smirk in the S&P500 futures options prices: a linearized factor analysis

In the S&P500 futures options, we identify three factors, corresponding to movements in the underlying, parallel movements, and tilting of the cross section of implied volatilities (the “smirk factor”). We relate these factors non-linearly to movements in the option prices. They seem to be diffusive in nature, have significant associated risk premia, and can account for an overwhelming part of the option price movements. We interpret the options smirk, which is the notion that out-of-the-money (OTM) puts seem expensive relative to OTM calls, in terms of the prices of these risk factors. Going short OTM puts and long OTM calls, corresponding to the third factor, makes a profit on average, but this corresponds to its risk premium, and does not represent a market inefficiency. Our smirk factor is useful for hedging option portfolios, but seems unrelated to movements in the underlying, and does not fit into the framework of the jump-diffusion models.      

投资者结构与期限结构对期货市场效率的影响研究

有效市场假设认为,投资者不能通过任何信息的获取而获得超额收益,即价格能够及时地反映所标资产的相关信息和风险。通过对上海期货市场金融危机前后交易数据的检验,发现其存在显著的长期惯性利润,证明了其不符合有效市场假设和可能存在市场操纵行为。Granger因果检验进一步发现短期的投机行为越多惯性利润越低,长期惯性利润越高投机行为越多。因此上海期货市场有必要通过减少交易成本和提供更多的交易信息去改善市场结构和效率。     

The predictive performance of the currency futures basis for spot returns

This paper investigates the predictive performance of the futures basis in directly forecasting currency spot returns and compares it with that of the one-month forward basis. We consider the settle prices of both front-month and nearby-month continuous futures contracts and find that the futures basis exhibits statistically and economically significant in-sample and out-of-sample forecasting power, which clearly exceeds that of the well-known forward basis. The empirical results show that spot returns correspond negatively to both the front-month futures basis and nearby-month futures basis. Furthermore, the futures basis reveals substantial economic value for investors in terms of sizable and tangible portfolio gains, which are consistent with statistical measures. The difference in the forecasting ability of the futures basis and forward basis can be explained by the level of exposure to the time-varying risk premium. Finally, we find that impacts of the futures basis on spot returns vary with time and experienced substantial structural changes during the Global Financial Crisis.     

The impact of lunchtime closure on market behaviour: evidence from the Sydney Futures Exchange

This paper examines the impact of lunchtime closure on market behaviour. Between May and September, 1994 the Sydney Futures Exchange trialed lunchtime trading. The trial provides a unique natural laboratory experiment for examining the impact of lunchtime closure. The analysis reported in this paper documents abnormally high bid ask spreads, price volatility and trading volume on re‐opening of the market following lunchtime closure. These results confirm that closure has an impact on trading activity, and are consistent with the effects of strategic informed trading, a loss in price discovery and/or trading associated with risk transfer. An abnormal increase in trading volume prior to lunchtime closure is also documented, providing unambiguous evidence of trading activity motivated by risk transfer. Overall these results imply that lunchtime closure disrupts trading activity and reduces market quality by imposing additional costs on market participants.

国际原油价格对我国新能源行业股票价格的波动溢出效应研究

在大气污染日益严峻的情况下,新能源行业受政府大力支持和投资者青睐。新能源与原油一定程度上互为替代品,理论上国际原油价格必然对我国新能源行业股票价格有显著的波动溢出效应,但有些学者却持反对态度,认为我国股票市场对外还没有完全开放,新能源行业发展又很不成熟,所以该溢出效应很难显著。文章运用VAR- Asymmetric- BEKK模型进行比较研究得出：在未去除我国整体股市行情因素时,国际原油价格波动对我国新能源行业股票价格波动溢出效应不显著;而在去除我国整体股行情因素时,国际原油价格波动对我国新能源行业股票价格波动溢出效应在1%显著性水平下显著。表明存在从国际原油价格向我国新能源行业股票价格的波动溢出效应,只是该溢出效应被我国股市总体行情掩盖了。     

Capturing the risk premium of commodity futures: The role of hedging pressure

We construct long–short factor mimicking portfolios that capture the hedging pressure risk premium of commodity futures. We consider single sorts based on the open interests of hedgers or speculators, as well as double sorts based on both positions. The long–short hedging pressure portfolios are priced cross-sectionally and present Sharpe ratios that systematically exceed those of long-only benchmarks. Further tests show that the hedging pressure risk premiums rise with the volatility of commodity futures markets and that the predictive power of hedging pressure over cross-sectional commodity futures returns is different from the previously documented forecasting power of past returns and the slope of the term structure.     

The effectiveness of position limits: Evidence from the foreign exchange futures markets

This study considers the effects of the relative size of hedger and speculator open interests and the potential impact of implementing position limits on the price discovery process in both JPY–USD and EUR–USD futures markets. Hedging trading exerts a negative impact, regardless of its size, on price discovery in futures markets. Hedgers are less likely to be information motivated, so their trading uniformly delays the price discovery process. However, there is a positive and nonlinear impact of speculators’ trade size on price discovery, the contribution of which depends on the relative size of the speculative open interest. Contrary to conventional wisdom among regulators, speculative trading does not harm the market in terms of market efficiency; as long as the percentage of speculators’ open interest is below an endogenously determined threshold (approximately 20% for EUR–USD and 16.3% for JPY–USD), speculative trading even improves futures market efficiency.     

Governing the transition to low-carbon futures: A critical survey of energy scenarios for 2050

There is a growing scientific consensus that limiting the increase in global average temperature to around 2 °C above pre-industrial levels is necessary to avoid unacceptable impact on the climate system. This requires that the developed countries’ emissions are radically reduced during the next 40 years. Energy scenario studies provide insights on the societal transitions that might be implied by such low-carbon futures, and in this paper we discuss how a greater attention to different governance and institutional issues can complement future scenario exercises. The analysis is based on a critical review of 20 quantitative and qualitative scenario studies, all of relevance for meeting long-term climate policy objectives. The paper: (a) analyzes some key differences in energy technology mixes and primary energy use patterns across these studies; (b) briefly explores the extent and the nature of the societal challenges and policy responses implied; and (c) discusses a number of important implications for the design and scope of future scenario studies. Our review shows that in previous scenario studies the main attention is typically paid to analyzing the impact of well-defined and uniform policy instruments, while fewer studies factor in the role of institutional change in achieving different energy futures. We therefore point towards a number of strategies of integrating issues of transition governance into future scenario analyses, and argue for a closer synthesis of qualitative and quantitative scenario building.

Implications of Applying a Private Sector Based Reporting Model to Not-for-Profit Entities: The Treatment of Charitable Distributions by Charities in New Zealand

In this paper, we investigate the practical and conceptual difficulties caused by applying a private sector based reporting model to the not-for-profit sector. We deal specifically with reporting on charitable distributions by charities in New Zealand. We find a majority of the entities report charitable distributions in the Statement of Financial Performance (as expenses). This approach is conceptually justifiable, complies with international best practice, and is in line with the accountability argument made in this paper. While the number reduced between 2003 and 2007, a significant minority of the entities report charitable distributions in the Statement of Movements in Equity (and therefore report higher surpluses). These two approaches lead to very different results, yet both are apparently seen as acceptable by the entities and their auditors. While this raises questions as to the understandability and comparability of the financial reporting by these entities, it also raises questions about the suitability of the for-profit sector reporting requirements for the not-for-profit sector.     

The history of Western futures studies: An exploration of the intellectual traditions and three-phase periodization

The main purpose of this paper is to present a three-phase periodization of modern Western futures studies to construct historical classification. In order to reach this goal, the following intellectual traditions are introduced to review the philosophical and historical contexts that affect the very foundations of futures studies: (a) religions, (b) utopias, (c) historicism, (d) science fiction, and (e) systems thinking. The first phase (beginning in 1945 to the 1960s) was the era of scientific inquiry and rationalization of the futures characterized by the prevalence of technological forecasting, the rise of alternative futures in systematic ways, and the growth of professionalization of futures studies. In the first phase, futures had become objects of rationalization removed from the traditional approaches such as utopia, grandiose evolutionary ideas, naive prophecies, science fiction, religious attitudes, and mystical orientation. The second phase (the 1970s and the 1980s) saw the creation the global institution and industrialization of the futures. This era was marked by the rise of worldwide discourse on global futures, the development of normative futures, and the deep involvement of the business community in futures thinking. In the second phase, futures studies-industry ties were growing and the future-oriented thoughts extensively permeated the business decision-making process. The third phase (the 1990s – the present) reflects the current era of the neoliberal view and fragmentation of the futures. This phase is taking place in the time of neoliberal globalization and risk society discourses and is characterized by the dominance of foresight, the advance of critical futures studies, and the intensification of fragmentation. In the third phase, futures practice tends to be confined to the support of strategic planning, and hence is experiencing an identity crisis and loss of its earlier status of humanity-oriented futures.

The effectiveness of incorporating higher moments in portfolio strategies: evidence from the Chinese commodity futures markets

This paper examines portfolio strategies that incorporate individual and systematic higher-order moments, within a stochastic optimization framework with uncertain mean and covariance. Using weekly, daily, and 30-minute interval data on Chinese commodity futures, we show that incorporating higher moments into portfolio strategies generally leads to better performance. The systematic fourth-order moment, among all systematic moments considered, can lead to the most robust, and a relatively large, improvement in investment performance, while the contribution of individual moments to the improved performance depends on the data horizon. We also find that adding higher moments brings superior performance in more cases for 30-minute-interval data than for other low-frequency data, suggesting that our strategy most likely performs best in 30-minute-rebalancing investments.     

The impacts of large trades by trader types on intraday futures prices: Evidence from the Taiwan Futures Exchange

We find that China's P/E ratio is comparable to that of the U.S. S&P 1500 index, a broad based index covering large, middle, and small capitalization firms. We provide an explanation as to why China's seemingly low P/E ratio is not surprising in light of the economic growth that it has experienced. Specifically, we show that (i) the P/E ratio is negatively associated with earnings volatility in both the Chinese and U.S. stock markets with an economically significant magnitude; and (ii) historical earnings volatility is considerably higher in China than in the U.S. Higher earnings volatility in China offsets higher growth prospect in setting the P/E ratio, making its P/E ratio much closer to what is observed empirically than otherwise implied by its growth rate.     

How numbers of the future are shaping today: The role of forecasts and calculations in public sector strategic thinking

This article examines the role of numbers in forming a city strategy in the case of Gothenburg, Sweden. The article illustrates how numbers make people act and react and shape the strategy process. The study is situated between the theoretical fields of accounting and strategy processes in cities. By relating them to the concept of ‘governmentality’, numbers are seen as helping render the city governable. Because strategizing is seen as concerning the future, the actors involved in drafting the strategy feel free to challenge historically institutionalized practices. The effect is paradoxical: the future‐looking strategy process becomes a forum for solving current problems.
