An Econometric Analysis Elisavet Porlida Sotirios Kafaridis SCHOOL OF ECONOMICS, BUSINESS ADMINISTRATION & LEGAL STUDIES A thesis submitted for the degree of Master of Science (MSc) in Banking & Finance November 2016 Thessaloniki – Greece Students Name: Sotirios Kafaridis Elisavet Porlida SID: 1103150009 1103150022 Supervisor: Dr. Panos Pouliasis Co-Supervisor: Dr. Hanno Friedrich We hereby declare that the work submitted is ours and that where we have made use of another‟s work, we have attributed the source(s) according to the Regulations set in the Student‟s Handbook. November 2016 Thessaloniki – Greece Abstract The main purpose of this dissertation, after providing an extensive review with respect to the major characteristics of maritime industry, is to examine the extent of which the freight rates affect the stock performance of shipping companies. In order to do so, we conducted an empirical analysis by regressing the returns of Dow Jones Global Shipping Index (R_DJGSH), which comprises the 25 highest ranked shipping companies by indicated annual yield, on the returns of Baltic Dry Index (R_BDI), a major freight rate indicator. We expected that the higher the price of freights the better the stock performance of the shipping companies. The results that came up after the analysis confirmed the aforementioned positive relationship. Later on, we tried to examine whether the addition of one more independent variable, this of the returns of Crude Oil Index (R_CLC1), will provide a better interpretation to our investigation. Crude Oil is added due to the fact that it is one of most important factors when evaluating the transportation costs of a shipping voyage; It is estimated that almost half of the total cost of a shipping voyage is attributed to fuel costs, thus, the fluctuations of crude oil are likely to have a major impact on the profitability of shipping companies. As expected, the addition of R_CLC1 enhanced significantly the predicting ability of our model. The data have been collected in a time period between September 2006 and September 2016 on a weekly basis and were extracted from Thomson Reuters “Eikon”. We ran econometric tests for stationarity for all the three variables, by using unit root tests, i.e., Dickey Fuller (DF), Augmented Dickey Fuller (ADF) and the stationarity test Kwiatkowski–Phillips–Schmidt–Shin (KPSS). Further on, we estimated simple and multiple linear regression models, and tested the significance of the independent variables by using the Stepwise selection method. Finally, we tested if the five principal assumptions for the use Ordinary Least Squares (OLS) estimators are valid in our regression model and, in particular, we ran statistical tests in order to check the existence of heteroscedasticity, autocorrelation and normality among the residuals, as well as the existence of multicollinearity between the explanatory variables. All the tests have been run in the statistical package of “E-Views”. The conclusion is that both the R_BDI and R_CLC1 are statistically significant, the regression model meets all the assumptions and explains sufficiently the total variability of R_DJGSH at a percent of 20%.

However, compared to traditional time series approaches, there are few studies using artificial intelligence techniques (e.g. artificial neural networks - ANNs) to forecast shipping freight rates, and fewer still incorporating forward freight agreement (FFA) information for accurate freight forecasts.

Moreover, this study provides the most effective parameters for Baltic Dry Index (BDI) prediction and an optimal model by analyzing and comparing deep learning models such as the artificial neural network (ANN), recurrent neural network (RNN), and long short-term memory (LSTM). Design/methodology – This study uses various data models based on big data. The deep learning models considered are specialized for time series models. This study includes three perspectives to verify useful models in time series data by comparing prediction accuracy according to the selection of external variables and comparison between models. Findings – The BDI research reflecting the latest trends since 2015, using weekly data from 1995 to 2019 (25 years), is employed in this study. Additionally, we tried finding the best combination of BDI forecasts through the input of external factors such as supply, demand, raw materials, and economic aspects. Moreover, the combination of various unpredictable external variables and the fundamentals of supply and demand have sought to increase BDI prediction accuracy.

    Erasmus University Rotterdam MSc in Maritime Economics and Logistics 2016/2017 ‘What is the influence of seasonality on the spot index freight rates for the dry bulk shipping market? By Anastasios Karanikos 1 copyright © [Anastasios Karanikos] Acknowledgments I would like to thank my supervisor Mr Welten for his valuable suggestions during the process of this thesis. I appreciated his willingness to help me and give me essential advices. I would also like to thank my family and my friends for their psychological support throughout this period. Lastly, I would like to thank my colleagues for their advices and support during the academic year. 2 copyright © [Anastasios Karanikos] Abstract The dry bulk market has a leading role in the formation of trade market. However, it is mainly characterized by seasonality and volatile prices which may be caused by a variety of reasons such as weather conditions and local legislation. Therefore, the involved parties may take an economic risk attributed to the fluctuation in the value of freight rates. By understanding the seasonal pattern and business cyclicality with the use of shipping derivatives this risk may be eliminated as much as possible. In this thesis, the nature of seasonality (deterministic and/or stochastic) for four different types of dry bulk vessels (Capesize, Panamax, Supramax and Handysize) is examined for the period 2010-2016. The results do not reveal evidence of stochastic seasonality, while the deterministic seasonality varies from -44% to 29% in individual months for each year. Moreover, different vessel sizes showed differences in seasonal fluctuations, with bigger vessels being subjected to higher seasonal fluctuations compared to smaller ones.

  • SPPI Perspective of Broker Activity in Sea Transport
    ROME 24 | 28 SEPTEMBER 2018 SPPI perspective of broker activity in sea transport CRISTINA CECCONI Istat – Italy 2 TITLE ROME 2018 SPPI PERSPECTIVE OF BROKER ACTIVITY IN SEA TRANSPORT 1. Introduction1 This paper provides an overview of the sea transport sector highlighting broker activity and its features. Paragraph 2 briefly describes the maritime industry and its market conditions; Paragraph 3 presents the broker role; Paragraph 4 explains the involvement of brokers in the Italian sea transport producer price index and Paragraph 5 concludes. 2. The sea transport in Italy 2.1 Features The sea transport sector is very important for modern societies. Increasing globalisation has led to a strong increase in international shipping activity: trade and shipping are closely linked. Historically, the shipping industry has increased both in its fleets and in the total trade volume capacity. Shipping has long been the major form of transport and, like the rail transport, it is economically and environmentally a very efficient way to transport goods. At the same time, there has been an important increase of other traditional sea-related activities too. According to the Eurostat Glossary, sea transport is made of both the so-called deep sea shipping which refers to the maritime transport of goods on intercontinental routes, crossing oceans, and the short sea shipping that is the transport of goods over relatively short distances. While this definition refers only to goods, the OECD Glossary of statistical terms definition is more general and mentions any movement of goods and/or passengers using seagoing vessels on voyages, which are undertaken wholly or partly at sea.

  • Baltic Code 2020 & an Introductory Guide to Modern Shipping
    GGuide to Baltic Code 2020 & An Introductory Guide to Modern Shipping Introduction This document is primarily designed to be a Guide to the New Baltic Code and provides a framework for how the New Baltic Code is applicable to, and can be utilised by, the maritime markets. It includes the introductory guide to modern shipping and terminology which many new Baltic Exchange Members have found useful. Capitalised terms used herein and otherwise not defined have the meaning given to them in the New Baltic Code. The Role and Organisation of the Baltic Exchange The Baltic is the world's oldest shipping market. It traces its name to the Virginia and Baltick Coffee House, established in 1744. At this time, it was used mainly by merchants who had a maJor trade in tallow from the Baltic seaboard. The Baltic Exchange was reorganised into its modern corporate form at the time of the construction of the original Baltic Exchange building in St Mary Axe which opened in 1903. After this building was destroyed by an IRA bomb in 1992, the Baltic Exchange moved into its current headQuarters at 38 St Mary Axe. The Baltic developed into the world’s most prestigious and only international, self-regulated market for matching ships and cargoes and buying and selling ships. Although in the light of modern business practice and international communications, a trading floor is no longer necessary, the Baltic's global Members continue to operate as a shipping marketplace and to apply the highest standards of ethics. A large part of the world's ship chartering and Sale & Purchase business is negotiated at some stage by Members of the Baltic.

  • The Volatility in the Dry Bulk Panamax Segment Panagiotis Demeroukas
    Erasmus University of Rotterdam MSc in Maritime Economics and Logistics 2013/2014 The Volatility in the Dry Bulk Panamax Segment by Panagiotis Demeroukas Copyright © Panagiotis Demeroukas i Acknowledgements I would like to express my great appreciation to my supervisor Mr Lafranca for his valuable and constructive suggestions during the planning and development of this thesis. His willingness to give his time so generously has been very much appreciated. I am also grateful for the support, emotional and psychological that I received from my family throughout this difficult and stressful period. Last but not least I would like to thank my friends and colleagues for their support and advices throughout this academic year and especially Mar for her valuable help. Page | ii Abstract The world dry bulk shipping is characterized as a volatility industry and especially after the long lasted peak of 2003 the market is much more perplex. This research paper’s aim is to find and analyze the volatility of the dry Panamax sector. This study is based on quantitative analysis using the Eviews 7 software. A sample of 2908 daily and 140 monthly observations of daily earnings of various Panamax routes and 1587 daily observation of the contract prices of the Forward Freight Agreements were used. The sample periods were from 1 November 2002 to 27 June 2014 and from 1 August 2007 to 2 December 2013 for the daily index, monthly index and the FFAs respectively. Applying the descriptive statistics measurements a brief overview has been obtained of the distribution of the indexes. With the application of the EGARCH there is an asymmetry impact between past shocks and current volatility.
