Forecasts of the managed futures market – an empirical analysis

Alternative investments, including managed futures, are primarily intended for institutional investors and for very wealthy individual investors. It therefore seems logical to assume, that the increase of wealth on a global scale can be a factor impacting the value of transactions in individual segments of the alternative-investment market. The purpose of this article is to indicate the factors affecting growth of managed futures transactions. Another research goal is to answer the question: Does the increase of wealth on a global scale affect the value of the managed futures transactions? The article will also present short-term forecasts of the transactions on the managed futures market for the years 2015–2017. The forecasts which will be constructed are meant to present possible scenarios of the market’s further development. Evolution of the alternative investment segment leads to development of those categories, which fulfil the expectations of market participants and meet the requirement and expiration of the remaining investments which do not attract investors and are no longer accepted by them.     

Stock-bond decoupling before and after the 2008 crisis

In this article, we analyse the co-movements of daily stock prices and government bond prices during the last 25 years, in major Western stock markets, extending previous results to take into account the impact of the current crisis. Our results confirm that bonds are viewed as instruments for improving portfolio diversification in periods of high volatility and falling stock market levels, which is when such diversification is most needed. The possibility of using government debt in portfolios as a means of hedging during times of financial crisis became especially apparent in the crises of 1997, 2001 and 2008. Nevertheless, during the current one, this diversification quality of bonds has disappeared in countries like Italy or Spain, which are also affected by sovereign debt issues.     

Does diversity matter? A fresh inquiry into the energy,economy and environment nexus

ABSTRACT

The article extends the literature on the nexus among economy, environment and energy by incorporating an index of electricity generation diversity in production and emission functions. The index is mathematically equivalent to Herfindahl–Hirschman index. The index captures substantial information regarding the ongoing energy transition at the global level. The results obtained through pooled mean group estimation, on a dataset of fairly diversified group of countries, indicate that if diversity index increases by a percentage point, per capita income increases by 2.4% and per capita emissions are reduced by 0.71%. This is against the conventional wisdom in favour of specialization. The study has found some interesting long-run causal pathways. Firstly, the causality runs from diversification to income. Secondly, there is a causality running from electricity consumption to specialization. Thirdly, bi-directional causality runs between emissions and specialization. The results have interesting policy implications. The study supports the growth hypothesis that the electricity consumption drives the economy. As this inevitably increases emissions, a better pathway is through diversification. The fossil fuel intensive pathway may have been the preferred choice in the past for countries with low electricity consumption; the diversified portfolio appears to be prudent in the future.     

熵指数的可分解特性及其在多元化测度中的应用

熵是对不确定性的度量,被广泛应用于多个学科领域。可分解特性是熵统计量的良好品质,它使事件的总体熵可以分解为类间熵和平均的类内熵。这种特性应用到公司多元化水平的测度中,可以有效地解决多元化指数在统计分析中的多重共线性问题。

Are exchange rates interdependent? Evidence using wavelet analysis

We examine the co-movement in daily returns of USD–INR, EUR–INR, GBP–INR, and JPY–INR currency pair futures contracts traded on the National Stock Exchange of India (NSE) using the wavelet cohesion approach. This study contributes to the literature by examining the scantly studied area of co-movement in exchange rates and using the wavelet approach, which allows us to analyse time–frequency-wise co-movement of the time series. The empirical results indicate that the currency futures markets are nearly perfectly integrated in the long run (monthly, quarterly and biannual scales) offering little potential gains from international portfolio diversification. The discrepancies between currency futures markets are small and almost fade away within 3–6 months. Moreover, international currency diversification might offer relatively higher potential gains at intraweek, weekly, and fortnightly time horizons owing to lower correlations among the currencies under consideration. Finally, our multiple-wavelet correlation and cross-correlation analysis shows that GBP acts as a potential leader/follower across scales. The results of our analysis indicate the dynamic pattern of co-movement among the major currency futures contracts, which provides several implications for portfolio managers and international investors participating in the Indian market.     

艺术品的金融属性：投资收益与资产配置*

本文基于2000—2014年中国艺术品拍卖市场近现代国画的微观数据,在资产配置中引入市场交易机制中的佣金变量,加入艺术品市场规模约束,采用重复交易法实证计量嵌入艺术品市场的投资收益特征并量化其资产配置效应,以测度其市场功能。优质的艺术精品具备金融资产风险和收益的基本特征,本文对艺术品资产与资本资产定价模型的适应性进行讨论。研究表明：在样本期内,剔除通胀和佣金成本因素后收益率更加贴近现实,中国艺术品投资的实际收益率水平为1308%,表现出高于欧美市场的投资溢价;艺术品投资与传统的股票、债券等金融资产之间表现出相对独立性,并能有效改善投资者资产组合的风险边界,可以成为资产配置优化和多样化的重要选择。中国艺术品市场的长期稳健发展将为投资者提供更多的资产优化产品和工具。     

Bitcoin—A hype or digital gold? Global evidence

This study explores whether Bitcoin constitutes as a hedging instrument whilst seeking portfolio diversification opportunities among sustainable, conventional and Islamic asset classes since Bitcoin emerges as a distinct alternative investment and asset class across the world. We apply multivariate generalised autoregressive conditional heteroscedastic-dynamic conditional correlation and continuous wavelet transforms based on the recent data set ranging from August 18, 2011, to September 10, 2018. First, our findings show that Bitcoin returns are mean-reverting which implies that its value tends to come down to mean value in the long run and not completely crushed to zero irrespective of price changes suggesting Bitcoin as a sustainable asset class. Second, the time-invariant model shows that Bitcoin offers portfolio diversification opportunities with almost all equity indices, in particular, Dow Jones Islamic followed by FTSE 4 Good index. Finally, the time-variant analysis reconfirms that Bitcoin offers portfolio diversification benefits both in the short and long run. These findings carry meaningful policy considerations for fund managers and cross-country investors.

Joint Adjustment of House Prices, Stock Prices and Output Towards Short‐run Equilibrium

A dynamic IS‐LM model including houses and stocks as additional assets will be analysed in this paper. Providing also housing services, a major consumption item for most households, houses create an additional link between the monetary and the real sector, distinct from the traditional wealth effect channel. We analyse the adjustment path of output, house prices and stock prices after policy shocks within a rational expectation setup. Depending crucially on the elasticity of housing services demand, different reaction patterns of asset prices will emerge. The results are contrasted with relevant empirical findings, particularly Lastrapes (Journal of Housing Economics, 11 (2002), pp. 40–74), leading to the identification of plausible elasticity ranges. The analysis sheds new light on the ongoing discussion about demand effects from changing real estate wealth and about determinants of house price fluctuations.
