Asset pricing anomalies: Evidence from oil industry (original) (raw)

Oil Price Fluctuations and Industry Stock Returns

This study investigates the impact of oil price variation on 14 industries in six markets, including Canada, China, France, India, the United Kingdom, and the United States. Panel weekly data were collected from June 1998 to December 2011. The results indicate that price fluctuations primarily affect the Oil and Gas as well as the Mining industries and have the least influence on the Food and Beverage industry. Furthermore, in three out of six of these countries (Canada, France, and the U.K.), oil price changes negatively affect the Pharmaceutical and Biotechnology industry. One possible reason for the negative relationship between oil price changes and the Pharmaceutical and Biotechnology industries in the above-mentioned countries is that the governments of these countries fund their healthcare systems. Portfolio managers and investors will find the results of this study useful because it enables adjusting portfolios based on knowledge of the industries that are impacted the most ...

International Review of Financial Analysis What do we know about oil prices and stock returns

This paper is a survey of research on how oil prices affect stock returns. In the last couple of decades there has been an upsurge in such research, suggesting that a stock take is timely. The sheer volume of research on the interaction between oil markets and stock markets has meant that we have lost track of the key findings from the literature. The danger, in the absence of a stock take, is that we will produce a large volume of studies on how oil prices interact with stock returns without them having any real impact on the profession. This paper is a response to this concern. It highlights the key themes researched, main findings and, equally importantly, identifies key challenges and suggests an agenda for future research on the interaction between oil prices and stock returns and oil prices and the financial sector more generally.

The importance of oil assets for portfolio optimization: The analysis of firm level stocks

JEL classification: C22 C32 G11 G12 G15 G19 This study aimed to analyze the shock transmission and volatility spillover between firm stocks and oil assets by using the BEKK-GARCH model in which a variance and covariance series are used for portfolio optimization. For this purpose, we use the daily data from 107 Pakistani-listed firms covering the period from January 2000 to August 2017. Our overall results confirm the interdependence between firm stocks and oil assets. Additionally, there is strong evidence of volatility spillover from stocks to oil and from oil to stocks. The results from the portfolio optimization show the importance of oil assets in the formation of an optimal portfolio. Moreover, we find that in the case of manufacturing firm stocks, the investors should spend N50% of their total investment to purchase oil assets, while the remaining investment should be used to acquire firm stocks. On the other hand, in the case of investments in oil and gas firm stocks, it is evident that investors can form an optimal portfolio by spending a larger proportion of their investments on firm stocks rather than on oil assets. This research implication can be valuable for portfolio managers and individual investors who are willing to invest in Pakistani stocks.

An Empirical Analysis of the Relationship between Oil Prices and Stock Markets

International Journal of Economics and Finance

This paper investigates the relationship between oil prices and stock market returns for the G7 and the BRIC countries for the period 1991-2016 using cointegration and a vector error correction model. Results reveal that there is no long-run relationship between oil prices and the stock market indices of the G7 countries. However, they also reveal that there is a long-run relationship between oil prices and the stock market indices of three out of the four BRIC countries (Brazil, China and Russia). This result appears to be broadly aligned with the idea that over the past quarter of a century emerging countries have been more exposed to oil prices (either as producers or consumers) than developed ones. Furthermore, from an investments’ and international portfolio management perspective, it seems that there might be benefits from diversification when holding the stock market index of a G7 country or India and oil assets since these appear to be segmented. On the other hand, such bene...
