Forecasting stock index volatility : comparing implied volatility and the intraday high-low price range

The intraday high–low price range offers volatility forecasts similarly efficient to high-quality implied volatility indexes published by the Chicago Board Options Exchange (CBOE) for four stock market indexes: S&P 500, S&P 100, NASDAQ 100, and Dow Jones Industrials. Examination of in-sample and out-of-sample volatility forecasts reveals that neither implied volatility nor intraday high–low range volatility consistently outperforms the other.

Hurdle rate : executive stock options

Executive stock options with a rising strike price are a recent innovation in executive compensation in Australia and New Zealand. These options combine a dividend protection feature and a strike price that increases at a hurdle rate set with reference to a cost of capital estimate. With a constant dividend yield, the strike price becomes a path-dependent function of the stock price and exact analytic valuation becomes intractable. However, path-dependent American options can be valued using a Monte Carlo approach proposed in Longstaff and Schwartz (2001). We examine procedures for valuing these options and compare them with Black and Scholes (1973) and Merton (1973) formula valuations.

Cultural impact on entry mode strategies into Chinese market by Australian companies

This Paper examines the cultural impact on the choice of entry mode strategies of Australian companies entering the Chinese Market. The Paper stresses the view that cultural differences must be considered when making entry mode  decisions. The evidence gained from an analysis of case studies undertaken of two Australian companies is presented in this paper. In both cases cultural differences have major affects on the decision-making process of China operations at a strategic level. It also indicates that a uniform process of entry mode stages, as suggested in the literature on entry options, may not be  suitable. Entry mode strategy should be determined on a case-by-case base and evaluated with culture considered prior to other criteria.

Transnational higher education : a stock take of current activity

Transnational higher education (TNHE) development is not an entirely new international activity in the education services sector. The nature and scale of the global expansion of contemporary TNHE developments are, however, changing substantially. An understanding of this growth is currently largely lacking because of a dearth of comprehensive statistics. The scale of the latter TNHE developments has been particularly hard to identify and has until now been largely based on guesstimates. This article is an attempt at filling this gap. Through a triangulation methodology of available secondary data, this article is a very first attempt at providing a stock take of the current level of activity in TNHE worldwide.

The role of the surveying profession in reducing carbon emissions of existing office stock in the Melbourne CBD

As professionals, surveyors and property professionals are in the front line and have a moral and ethical duty to take a lead when advising clients appropriately on measures to reduce greenhouse gas emissions from their buildings. As such, surveying professionals and the profession must increase their knowledge base and enhance their skills in respect of built environment sustainability. This research conducted a detailed analysis of energy efficiency in the Melbourne CBD office stock and examined all office buildings to identify what was likely to happen between 2005 and 2020 in respect of carbon emissions. The research profiled a business-as-usual or no change approach, a minor change approach, an intermediate approach, and a major change approach. The study examined variables such as building size, number of employees, occupancy levels, visual appearance and age. After modelling all CBD office buildings, it was recommended that an intermediate change scenario should be adopted. This course of action incorporates a transition period and includes increasing ‘green power’, increasing the number of employees per buildings, as well as reducing electricity and gas consumption. It was concluded that the surveying profession should adopt a proactive stance towards office buildings and climate change, which is currently being stifled by barriers such as a lack of education and perception concerning the long-term benefits of energy efficient office buildings. To date there has been much debate and promotion of policies to encourage the uptake of sustainability practices within the property sector; however, this research concludes that action is needed if targets are to be met.

Board structure and firm performance : evidence from India's top companies

Manuscript Type: Empirical

Research Question/Issue: This paper investigates the relationship between internal governance structures and financial performance of Indian companies. The effectiveness of boards of directors, including board composition, board size, and aspects of board leadership including duality and board busyness are addressed in the Indian context using two theories of corporate governance: agency theory and resource dependency theory.

Research Findings/Insights: The study used a sample of top Indian companies taking into account the endogeneity of the relationships among corporate governance, corporate performance, and corporate capital structure. The study provides some support for aspects of agency theory as a greater proportion of outside directors on boards were associated with improved firm performance. The notion of separating leadership roles in a manner consistent with agency theory was not supported. For instance, the notion that powerful CEOs (duality role, CEO being the promoter, and CEO being the only board manager) have a detrimental effect on performance was not supported. There was some support for resource dependency theory. The findings suggest that larger board size has a positive impact on performance thus supporting the view that greater exposure to the external environment improves access to various resources and thus positively impacts on performance. The study however failed to support the resource dependency theory in terms of the association between frequency of board meetings and performance. Similarly the results showed that outside directors with multiple appointments appeared to have a negative effect on performance, suggesting that "busyness" did not add value in terms of networks and enhancement of resource accessibility.

Theoretical/Academic Implications: The two theories of corporate governance, namely agency and resource dependence theory, were each only partially supported, by the findings of this study. The findings add further to the view that no single theory explains the nexus between corporate governance and performance.

Practitioner/Policy Implications: This study demonstrates that corporate governance measures utilized in developed economies related to boards of directors have some synergies and relevance to emerging economies, such as India. However, the nature of business structures in India, for example the large number of family businesses, may limit the generalizability of the findings and signals the need for further investigation of these businesses. The evidence related to multiple appointments of directors suggests that there may be support for restricting the number of directorships held by any one individual in emerging economies, given that the "busyness" of directors was negatively associated with firm performance.

The oil stock fluctuations in the United States

The goal of this paper is to examine whether the volatility of the growth in the US oil stocks has changed overtime, and if it has then whether or not this change is real. We find that the growth in volatility of oil stocks has declined overtime. We conduct a Monte Carlo simulation exercise to investigate whether this decline is real or an artefact of the growth definition. Our findings support the fact that the decline in growth volatility of oil stocks is an artefact of the growth definition. This is because a data generating process having a unit root with drift has a tendency to grow and thereby pulls the variance of growth down with time.

Using competencies in human resource management : case studies in Australian companies

This study investigated the use of competencies for human resource management in seven Australian companies. Despite advocacy for the use of competencies by Government Committees and Task Forces (For example Carmichael (1992), Mayer, (1992) and Karpin, 1995), and the existence of competency standards for eighty per cent of the Australian workforce, the competency approach has not been widely adopted. A review of the literature indicated that the term competency had several meanings with different implications for its use depending on the meaning. The study looked at how individuals have defined the term and applied the approach to human resource management practices. Interviews were conducted with Human Resource and Training managers, and operative staff in companies using competencies. How they defined the term, described the rationale for using competencies, and applied competencies to selection, training, performance appraisal and remuneration were determined. Case studies were written for each company to describe their particular application of competencies. Competencies were found to be defined in several ways by those interviewed. Some advantages of using competencies in human resource management applications were found. The amount of work involved in introducing the competency approach was described as a reason why competencies have not been more widely adopted.

Wealth effect of auditor switch during crisis and non-crisis period : the Malaysian experience

This study examines the auditor switch effect on share prices among listed companies in Malaysia, mainly the Second Board companies during economic crisis and the economic growth period. Data on companies listed on the KLSE that reported switching of auditors were gathered from the respective companies’ annual reports for the period of 1990 until 1999. Daily stock prices and the Second Board Index for an interval of 200 days windows were extracted from the KLSE Daily Dairy. The wealth effect of auditor’s switch was investigated using the market model event study methodology. The general findings of the study imply that it is consistent with the theory, the market reacts positively to news involving switching to higher prestige audit firms before the economic crisis but reacted negatively during the economic crisis. News involving switching to lower prestige auditors received negative reaction both before and during the crisis. This study postulate that the negative reaction to switches during the economic crisis (either to higher prestige or to lower prestige auditors) may be due to cost cutting exercise rather than obtaining qualified audit reports.

On the relationship between stock prices and exchange rates for India

In this paper, we apply several variants of the EGARCH model to examine the role of depreciation of the Indian rupee on India's stock market returns using daily data. Our findings suggest that volatility persistence has been high; depreciation of the rupee has increased volatility; and asymmetric volatility confirms that negative shocks generate more volatility than positive shocks. We also find that an appreciation of the Indian rupee over the 2002 to 2006 has generated more returns and less volatility.

Stock market efficiency withstands another challenge : solving the “sell in May/buy after Halloween” puzzle

Examining the years 1970 to 1998, Bouman and Jacobsen (2002) document unusually high monthly returns during the November-April periods for both United States (U.S.) and foreign stock markets and label this phenomenon the Halloween effect. Their research suggests that the Halloween effect represents an exploitable anomaly and has negative implications for claims of stock market efficiency.

Re-examining Bouman and Jacobsen’s empirical results for the U.S. reveals that their results are driven by two outliers, the “Crash” of October 1987 and the collapse of the hedge fund Long-Term Capital Management in August 1998. After inserting a dummy variable to account for the impact of the two identified outliers, the Halloween effect becomes statistically insignificant. This anomaly is not economically exploitable for U.S. equity markets. We extend the research to the S&P 500 futures contract and find no evidence of an exploitable Halloween effect over the period April 1982-April 2003.
