Title: Overreaction on the Swedish stock market Seminar date:2008-01-30 Course:Nek K01- Bachelor Thesis in Economics (15 ETCS) Authors: Advisor:Oskar Herbe and Ludvig Persson Hossein Asgharian Key Words:Overreaction, Anomalies, Market Efficiency, Contrarian investment strategies Purpose:The purpose of this thesis is to test if the overreaction hypothesis as originally described by De Bondt and Thaler is a good explanation model for the Swedish stock market. Further, our intension is to divide the stock market into three segments by company size, in terms of market capitalization, to control for size effects. Method:We have conducted this study by analyzing Swedish stock data in the period of 1989-2007. Within this time span, using overlapping formation periods, we have constructed two types of portfolios, winner portfolios and looser portfolios. The portfolios represent the 30 per cent best performing respectively worst performing stocks in terms of returns.

When the Network Strategy Is Not Enough -The Case of European Full-Service Airlines

The 1990s were one of the most profitable periods for European airline companies, mainly because of development of world economy and increasing globalisation trends. However, towards the end of the decade, a global economic downturn, high oil prices and new forms of competition turned the industry towards troubled times. The European air-travel industry had to face and accept the new airline business concept, called low-cost or no-frill airlines. In these conditions, traditional airlines had to rethink their strategies and question the old business model. As a response to the competition, European traditional full-service airlines formed alliances or networks to expand the route network and to increase efficiency.

Vägen till god användbarhet : En fallstudie inom informationsarkitektur med fokus på ett informations- och filhanteringssystem

Since Internet has become a more important and more certain source of information the user require greater and more demands than ever before on the layout and function of different web pages.

In a time when a company?s digital footprint plays an important role for the costumer and the transmitter it?s of utmost importance to have a steady, well-structured foundation to build new platforms of information on.But how do you manage to build a good foundation? Some of the most important key elements in Information architecture are Organizing, Navigation, Search and Labeling.The aim of this study was to create guidelines for a user-friendlier interface, by analyzing the principals and gathered data.

Projektrisk : en studie av svenska bygg- och anläggningsföretag

Background: Today businesses are largely structured in projects and temporary organizations. In many companies, the ability to pursue projects is decisive for the business efficiency and competitiveness. The risk literature do not discuss identification and handling ofproject risk in building- and construction companies to a large extent, which has led us to investigate how project risk can be treated and handled in Swedish building- and construction companies. Purpose: The purpose of this thesis is to cover and describe business risk in Swedish building- and construction projects with focus on different risks and risk tools, and also to modify a model for evaluating the business risk maturity. Realization: This thesis has both traces of a case study and a cross-section study and examines eight different companies that are active in the building- and construction business.

Fördelar och nackdelar med effektivitetssalsarbete : Operationssjuksköterskors erfarenheter

Storleksoptimering av en etanolfabrik för integrering med ENA Energis kraftvärmeverk. : Baserat på en regional energibalans mellan tillgång på etanolbränsle i Enköping kommun och producerad etanol med hjälp av tillgänglig ånga från ENA kraftvärmeverk.

AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power.  ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant.  As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol.  Etanolens framtid vilar på bra lösningar för framställning.  I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle.  Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.

En jämförelse av RDF och avfall som förbränningsbränsle

In the EU the amount of waste increased by 14 percent during the years 2000 to 2010. EU?s target to reduce waste generation runs parallel with the aim of increasing the efficiency and profitability aligned with energy recovery. In Sweden the energy recovery through incineration is increasing steadily, and 46 percent of the municipal solid waste (MSW) is treated by combustion. This report aims to examine the profitability of processing MSW into Refuse Derived Fuel (RDF) from an economic-, energy- and environmental perspective.

Uppvärmningssystem : Ekonomi, miljö och drift

This bachelor thesis aims at investigate how a specified house can optimize its energy consumption.Today the house often stands for the major part of the energy consumption in a consumers? life,whereas an energy optimization creates economic as well as environmental advantages. It is importantto make old houses more energy efficient, but putting high energy demands on new houses could beargued to be more important. The installations functions as both the heart and brain in a house, thusmaking it important to energy optimize these. Since the background describes the importance ofenergy efficiency and optimization in a house, the focus area of this report will be an investigation ofdifferent types of heating systems in order to be able to choose the one most suited for the house.Aspects considered when choosing the heating system was how economic the system is both inservice- and investment costs and how environmental and operational friendly the system is.Through literature reviews there were sufficient information gathered that served as a foundation whencomparing and choosing between the four systems - district heating, pellet-fired boiler, geothermalheating and solar heating.

Lönsam arbetsmiljö eller arbetsmiljö för lönsamhet? : en studie om effekter av systematiskt arbetsmiljöarbete

I studien undersöks hur införandet av ett systematiskt arbetsmiljöarbete kan påverka en organisation.

Utvärderingsmodell för förpackningar och dess hantering i dagligvaruhandeln : ? en jämförelse av ergonomi-, miljö- och logistikparametrar

Companies become more and more aware of the added values of the packaging. A well chosen and developed packaging can reduce the costs for the companies through reduced costs for transports, reduced quantity of waste and discards and increased goodwill for example. The companies? costs for salaries can also be reduced due to the increased packaging handling efficiency and the reduced costs for sick leave, reduced work capacity and rehabilitation etc. that can arise when handling poorly developed products and packaging.

Driftoptimering av torkmaskin : Driftoptimering av torkmaskin 3 vid Billerudkorsnäs Karlsborg AB

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

Just In Time : Effektivisering av materialflöden med hjälp av principer från Inventory Management och Production Management

AbstractManagement is a field that started getting attention in the beginning of the 20th century by Frederick Taylor. His publication is called the Principles of Scientific Management and is based on the principles of using scientific methods to find the best way of conducting each operation within a production facility. Many of Taylor?s principles may appear obsolete today but the matter of an effective material flow is still highly current. Efficiency is the relationship between the input into an operation and its result.

Projektering av en etanolfermenteringsanläggning i pilotskala med Biostilteknologi

AbstractThis degree thesis was made in cooperation with Chematur Engineering in Karlskoga.Many of the environmental issues of today are a result of the motor traffic. Consumption of fossil fuels harms our environmental through formation of carbon dioxide and other greenhouse gases. To get under control with our environmental issues it?s important to find substitutes for oil that are both cheap and environmentally friendly. Ethanol has a long history as a motor fuel and is both enviromentally friendly has a high efficiency.According to the EU commissions directives for motor fuels, 5, 75 % of all the fuels in Sweden should be renewable in 2010.
