Revisiting the roles of gold: Does gold ETF matter?

This study investigates whether the role of gold changes due to the introduction of gold exchange-traded funds (ETFs) using sample data of seven countries in which physically-backed gold ETFs have been issued. The results show that the traditional roles of gold do change after the introduction of gold ETFs, particularly in the corresponding stock markets. The functions of hedge and safe haven provided by gold wear off during the post-ETF period in stock markets. In currency markets, however, gold still serves as a hedge and safe haven asset, and such effects become stronger during the post-ETF period. Moreover, gold ETFs play a role of relative strong safe haven than the physical gold does while the leading (lagged) stock returns extremely decline. Like the purposes of using physical gold assets, gold ETFs also provide hedge and safe haven effects to the exchange rate risks. Therefore, we might confirm that physical gold could be largely replaced by gold ETFs and investors could utilize gold ETFs to avoid potential risks in financial markets.     

Gold shares or gold bullion—which is the better investment?

This paper examines, from the standpoint of the US investor, the illative merits of an investment in gold bullion vis-à-vis South African gold shares. Markowitz portfolio-selection techniques are used to examine the relative performance of gold bullion and SA gold shares quoted on the New York stock exchange over the period 1978 to 1983. It concludes that, on average, of the period examined gold shares have proved to be significantly better investments than gold bullion and considers possible reasons for this.     

上海黄金期货市场有效性的实证分析

黄金因为其兼有货币、商品和金融三大属性的特征历来受到人们的重视。今年年初黄金期货在上海期货交易所的上市,填补了我国长期缺乏金融期货的空白。同时管理层与市场各参与主体对黄金期货给予很高的期望与关注,因此研究上海黄金期货市场的有效性具有重要意义。通过运用ADF单位根检验、协整检验、误差修正模型以及格兰杰因果检验等时间序列与计量经济方法,对上海期货交易所黄金期货市场的有效性进行实证分析。结果表明,上海黄金期货市场尚未达到有效,并且黄金现货价格单向引导期货价格。

Structural analysis and forecast of gold price returns

Gold has multiple attributes and its price is affected by various factors in the market. This paper studies the dynamic relationship between the gold price returns and its affecting factors. Then we use the STL-ETS, neural network and Bayesian structural time series model to predict the gold price returns, and compare their performance with the benchmark models. The results show that the shocks of crude oil returns and VIX have the positive effect on gold price returns, the shocks of the US dollar index have the negative effect on gold price returns. And the fluctuation of gold price returns mainly depends on crude oil price returns shocks. STL-ETS model can accurately fit the fluctuation trend of the gold price returns and improve prediction accuracy.     

Nonlinear dynamics of gold and the dollar

Notwithstanding the widely held view that gold and the dollar are negatively correlated, we ask when and why gold and the dollar sometimes depart from their typical inverse relationship and go so far as to move in parallel. Using a threshold vector error correction model (VECM), we investigate the nonlinear relationship between gold and the dollar. We find evidence of short run positive correlation between gold and the dollar under extreme market conditions. Our result suggests that the hedging property of gold is influenced by the gold-dollar threshold process.

Enterprise systems in financial sector – an application in precious metal trading forecasting

The use of enterprise systems has become increasingly popular in the financial service industry. This paper discusses the applications of enterprise systems in the financial sectors and presents an application in gold price forecasting. We carefully examine the impacts of a few most widely assumed factors that have significant impact on the long-term gold price using statistical regression techniques. The analysis on our proposed linear regression mode indicates that the United States ultra scale of M2 money supply has been the most important catalyst for the rising price of gold, and the CRB index upward trend has also been the weighty factor for pushing up the gold price. In addition, the gold price has a low negative correlation with the Dow Jones Industrial Average, and low positive correlations with the US dollar index and the gold ETFs holdings.
