Tämän tutkimuksen tarkoituksena on selvittää, pystyykö teknistä analyysiä hyväksikäyttävä sijoittaja saamaan markkinatuottoa parempaa tuottoa Suomen osakemarkkinoilla. Tutkielman aineisto koostuu 24:stä vaihdetuimmasta osakkeesta Helsingin pörssissä. Nämä osakkeet muodostavat OMX25 –indeksin lukuun ottamatta yhtä osaketta, jota ei oltu vielä noteerattu tarkasteluperiodin alussa. Teknisen analyysin menetelminä käytetään neljää eripituista liukuvaa keskiarvoa (5, 20, 50 ja 100). Näistä muodostetaan liukuvien keskiarvojen kaksinkertaiset leikkausmenetelmät, joiden avulla saadaan osto- ja myyntisignaaleja kullekin osakkeelle. Tutkielman vertailukohteena käytetään perinteisen rahoitusteorian suosimaa osta ja pidä -strategiaa. Empiiristen testien tarkastelujakso on 1.1.2006 – 30.9.2010. Tutkielmassa havaittiin, että teknistä analyysiä hyväksikäyttäen voi saada markkinoita parempaa tuottoa, vaikka kaikki tulokset eivät olleet tilastollisesti merkittäviä. Tutkimuksessa ei otettu huomioon useista kaupoista syntyviä transaktiokustannuksia, veroja eikä korkotuottoa, jonka sijoittaja saisi pitäessään varoja esimerkiksi pankkitilillä ennen seuraavaa kauppaa. Erityisen huomionarvoista tässä tutkimuksessa oli se, että tekninen analyysi antoi sijoittajalle erittäin hyvän suojan finanssikriisin aikaiselta kurssilaskulta. Se antoi sijoittajalle selvän myyntisignaalin myydä osakkeet, ennen kuin kurssit alkoivat laskea rajusti.

Tämän tutkielman tavoite on tutkia vahvan brandin merkitystä ja syitä, miksi yritykset käyttävät sisältömarkkinointia brandin rakentamisessa, sekä selvittää mitkä ovat yritysten sisältömarkkinointi-investointien tavoitteet, odotetut seuraukset ja koetut hyödyt ja tulokset. Teoriaosassa esitetään empiriaosaa varten tarvittava akateeminen taustatutkimustieto. Empiria on toteutettu puoli-struktroiduilla kahdenkeskisillä puhelinhaastatteuilla. Haastateltavina ovat työn toimeksiantajan Calcus Kustannus Oy:n viisi asiakasta. Näiden yritysten liikevaihto vaihtelee 23-75M€ välillä, ja yritykset toimivat pääosin suomen B2B yritysmarkkinoilla. Haastateltavat henkilöt ovat yrityksissä vastuussa markkinointipäätöksistä. Tulokset osoittavat, että vahvalla brandilla on erittäin suuri merkitys yrityksen kasvun ja menestyksen kannalta, ja että yritykset käyttävät sisältömarkkinointia brandin rakentamisessa, koska se kasvattaa brandipääomaa tehokkaasti. Sisältömarkkinoinnilla yritykset pyrkivät kasvttamaan heidän asiakkaidensa branditietoisuutta ja brandiuskollisuutta, sekä brandinsa uskottavuutta jakamalla aidosti kiinnostavaa ja lisäarvoa tuottavaa sisältöä. Lisäksi yrityksen asiantuntija-, sekä mielipidejohtajaroolin vahvistaminen koettiin erittäin tärkeäksi. Sisältömarkkinoinnin koetaan olevan brandin rakentamisessa tehokkaampaa kuin traditionaalinen markkinointi, minkä vuoksi yritykset tulevat kasvattamaan sen osuutta markkinointisuunnitelmissaan tulevaisuudessa.

The Finnish electricity distribution sector, rural areas in particular, is facing major challenges because of the economic regulation, tightening supply security requirements and the ageing network asset. Therefore, the target in the distribution network planning and asset management is to develop and renovate the networks to meet these challenges in compliance with the regulations in an economically feasible way. Concerning supply security, the new Finnish Electricity Market Act limits the maximum duration of electricity supply interruptions to six hours in urban areas and 36 hours in rural areas. This has a significant impact on distribution network planning, especially in rural areas where the distribution networks typically require extensive modifications and renovations to meet the supply security requirements. This doctoral thesis introduces a methodology to analyse electricity distribution system development. The methodology is based on and combines elements of reliability analysis, asset management and economic regulation. The analysis results can be applied, for instance, to evaluate the development of distribution reliability and to consider actions to meet the tightening regulatory requirements. Thus, the methodology produces information for strategic decision-making so that DSOs can respond to challenges arising in the electricity distribution sector. The key contributions of the thesis are a network renovation concept for rural areas, an analysis to assess supply security, and an evaluation of the effects of economic regulation on the strategic network planning. In addition, the thesis demonstrates how the reliability aspect affects the placement of automation devices and how the reserve power can be arranged in a rural area network.

A trade-off between return and risk plays a central role in financial economics. The intertemporal capital asset pricing model (ICAPM) proposed by Merton (1973) provides a neoclassical theory for expected returns on risky assets. The model assumes that risk-averse investors (seeking to maximize their expected utility of lifetime consumption) demand compensation for bearing systematic market risk and the risk of unfavorable shifts in the investment opportunity set. Although the ICAPM postulates a positive relation between the conditional expected market return and its conditional variance, the empirical evidence on the sign of the risk-return trade-off is conflicting. In contrast, autocorrelation in stock returns is one of the most consistent and robust findings in empirical finance. While autocorrelation is often interpreted as a violation of market efficiency, it can also reflect factors such as market microstructure or time-varying risk premia. This doctoral thesis investigates a relation between the mixed risk-return trade-off results and autocorrelation in stock returns. The results suggest that, in the case of the US stock market, the relative contribution of the risk-return trade-off and autocorrelation in explaining the aggregate return fluctuates with volatility. This effect is then shown to be even more pronounced in the case of emerging stock markets. During high-volatility periods, expected returns can be described using rational (intertemporal) investors acting to maximize their expected utility. During lowvolatility periods, market-wide persistence in returns increases, leading to a failure of traditional equilibrium-model descriptions for expected returns. Consistent with this finding, traditional models yield conflicting evidence concerning the sign of the risk-return trade-off. The changing relevance of the risk-return trade-off and autocorrelation can be explained by heterogeneous agents or, more generally, by the inadequacy of the neoclassical view on asset pricing with unboundedly rational investors and perfect market efficiency. In the latter case, the empirical results imply that the neoclassical view is valid only under certain market conditions. This offers an economic explanation as to why it has been so difficult to detect a positive tradeoff between the conditional mean and variance of the aggregate stock return. The results highlight the importance, especially in the case of emerging stock markets, of noting both the risk-return trade-off and autocorrelation in applications that require estimates for expected returns.

Logistics infrastructure and transportation services have been the liability of countries and governments for decades, or these have been under strict regulation policies. One of the first branches opened for competition in EU as well as in other continents, has been air transports (operators, like passenger and freight) and road transports. These have resulted on lower costs, better connectivity and in most of the cases higher service quality. However, quite large amount of other logistics related activities are still directly (or indirectly) under governmental influence, e.g. railway infrastructure, road infrastructure, railway operations, airports, and sea ports. Due to the globalization, governmental influence is not that necessary in this sector, since transportation needs have increased with much more significant phase as compared to economic growth. Also freight transportation needs do not correlate with passenger side, due to the reason that only small number of areas in the world have specialized in the production of particular goods. Therefore, in number of cases public-private partnership, or even privately owned companies operating in these sub-branches have been identified as beneficial for countries, customers and further economic growth. The objective of this research work is to shed more light on these kinds of experiments, especially in the relatively unknown sub-branches of logistics like railways, airports and sea container transports. In this research work we have selected companies having public listed status in some stock exchange, and have needed amount of financial scale to be considered as serious company rather than start-up phase venture. Our research results show that railways and airports usually need high fixed investments, but have showed in the last five years generally good financial performance, both in terms of profitability and cash flow. In contrary to common belief of prosperity in globally growing container transports, sea vessel operators of containers have not shown that impressive financial performance. Generally margins in this business are thin, and profitability has been sacrificed in front of high growth – this also concerns cash flow performance, which has been lower too. However, as we examine these three logistics sub-branches through shareholder value development angle during time period of 2002-2007, we were surprised to find out that all of these three have outperformed general stock market indexes in this period. More surprising is the result that financially a bit less performing sea container transportation sector shows highest shareholder value gain in the examination period. Thus, it should be remembered that provided analysis shows only limited picture, since e.g. dividends were not taken into consideration in this research work. Therefore, e.g. US railway operators have disadvantage to other in the analysis, since they have been able to provide dividends for shareholders in long period of time. Based on this research work we argue that investment on transportation/logistics sector seems to be safe alternative, which yields with relatively low risk high gain. Although global economy would face smaller growth period, this sector seems to provide opportunities in more demanding situation as well.

The purpose of the thesis is to examine the long-term performance persistence and relative performance of hedge funds during bear and bull market periods. Performance metrics applied for fund rankings are raw return, Sharpe ratio, mean variance ratio and strategy distinctiveness index calculated of the original and clustered data correspondingly. Four different length combinations for selection and holding periods are employed. The persistence is examined using decile and quartile portfolio formatting approach and on the basis of Sharpe ratio and SKASR as performance metrics. The relative performance persistence is examined by comparing hedge portfolio returns during varying stock market conditions. The data is gathered from a private database covering 10,789 hedge funds and time horizon is set from January 1990 to December 2012. The results of this thesis suggest that long-term performance persistence of the hedge funds exists. The degree of persistence also depends on the performance metrics employed and length combination of selection and holding periods. The best results of performance persistence were obtained in the decile portfolio analysis on the basis of Sharpe ratio rankings for combination of 12-month selection period and the holding period of equal length. The results also suggest that the best performance persistence occurs in the Event Driven and Multi strategies. Dummy regression analysis shows that a relationship between hedge funds and stock market returns exists. Based on the results, Dedicated Short Bias, Global Macro, Managed Futures and Other strategies perform well during bear market periods. The results also indicate that the Market Neutral strategy is not absolutely market neutral and the Event Driven strategy has the best performance among all hedge strategies.

This thesis investigates the short-term stock price reaction to layoff announcements in Finland. It also studies whether the characteristics of the firm or the layoff announcement have an impact on the stock market reaction. Standard event study methodology was utilized to examine the stock price reactions to layoffs and to test the created hypotheses. The event pool consisted of 102 publicly disclosed layoff announcements that were announced during the time period from June 2008 to December 2013. The empirical results show that the stock market reaction is strongly positive in the pre-event period of -10 to -1 with CAAR of 2,69%. The reaction is however slightly negative on the event date with AAR of -0,57%. Based on the results the conclusion is that either the managers are timing the markets or the layoffs are seen as efficiency improving acts and the market becomes aware of such actions pre-event. Additionally different characteristic hypotheses are tested to find out whether they would explain the reaction. The characteristics are: the reason stated by the management, business cycle, industry group, prior performance, leverage-ratio, the size of the company, the size of the layoff and the duration of the layoff.

Tutkielman tavoitteena on selvittää osinkosuhteen, osinkotuoton ja omavaraisuusasteen vaikutus osakkeesta saatavaan kokonaistuottoon Suomenosakemarkkinoilla vuosina 2002–2013. Muuttujien kausaliteettisuhde kokonaistuottoon selvitetään regressioanalyysilla. Portfolioanalyysin avulla tutkitaan valittujen tunnuslukujen toimivuutta sijoitusstrategiana. Tutkimuksessa muodostetaan myös osinkosuhteen ja osinkotuoton yhdistelmänä tunnusluku, jolla pyritään maksimoimaan sijoittajan saama tuotto. Empiiriset tulokset osoittivat, että sijoittaja pystyy saavuttamaan ylituottoja hyödyntämällä edellä mainittuja tunnuslukuja osakevalinnassa. Osinkotuoton ja osakkeen kokonaistuoton välillä havaittiin positiivinen lineaarinen korrelaatio. Portfolioanalyysin perusteella sekä omavaraisuusasteen että osinkosuhteen osalta vaikutus sijoittajan saamaan riskisuhteutettuun kokonaistuottoon on ei-lineaarinen. Valittuja tunnuslukuja ja menetelmiä hyödyntäen sijoittaja saa parhaimman riskisuhteutetun tuoton valitsemalla sijoitussalkkuunsa osakkeita, joiden osinkosuhteen arvo sijoittuu toiseksi ylimpään kvartiiliin sekä osakkeita, joiden osinkotuotto on korkea ja omavaraisuusaste on samanaikaisesti alhainen.

Tämän Pro gradu –tutkielman aiheena on tutkia sijoittajien käyttäytymistä matalassa korkomarkkinassa. Työssä tutkitaan, ovatko Kymenlaakson Osuuspankin Private –asiakkaat käyttäytyneet rahoituksen klassisen teorian mukaan rationaalisesti. Lisäksi tutkielmassa tutkitaan, ovat asiakkaat nostaneet sijoituksiensa riskitasojaan saadakseen korkeampia tuottoja riskittömän koron ollessa matalalla. Tutkielmassa tutkitaan myös, onko sijoittajien ankkurina riskitaso vai tuottotaso sekä onko naisten ja miesten välillä eroja. Tutkielman teoriapohjana käytetään perinteisiä rahoituksen teorioita, kuten CAPM-mallia, SML-käyrää, riskitöntä korkokantaa, markkinatehokkuutta sekä behavioristista taloustiedettä. Tutkimus on kvalitatiivinen ja sen empiirinen on kerätty haastattelulomakkeella Kymenlaakson Osuuspankin Private –asiakkailta. Johtopäätöksenä voidaan sanoa, etteivät tutkimukseen osallistuneet henkilöt olleet käyttäytyneet rationaalisesti. Sijoituksien riskitasoa oli nostettu ja miehet olivat nostaneet sijoituksien riskitasoa enemmän. Päätöksenteossa naisille oli hieman merkittävämpää sijoituksien riskitaso, kun taas miehille tärkeämpää oli tuottotaso. Kaikista vastaajista 51,8%:lle tuottotaso oli merkittävämpi tekijä.

Uuden sähkömarkkinalain myötä sähkönjakeluverkonhaltijoille tuli velvoite parantaa verkkonsa toimitusvarmuutta tasolle, jossa verkon vikaantuminen myrskyn tai lumikuorman seurauksena ei aiheuta asemakaava-alueella asiakkaalle yli 6 tuntia kestävää keskeytystä eikä muilla alueilla yli 36 tuntia kestävää keskeytystä. 1.9.2013 voimaan astuneessa laissa toimitusvarmuuden parantamisen aikaraamiksi on määritetty 15 vuotta. Verkkoyhtiöt voivat päättää verkon saneerausstrategiasta itsenäisesti, mutta toimitusvarmuusvaatimuksiin vastaaminen vaatii monelta yhtiöltä laajamittaista verkon kaapelointia ja investointivolyymien kasvattamista. Verkon investoinneilla on vaikutuksensa verkkoyhtiöiden taloudellisessa valvonnassa, joka puolestaan on Energiaviraston vastuulla. Valvonnan kohteina ovat siirtohinnoittelun kohtuullisuus, toiminnan tehokkuus ja sähkön laatu. ElMil Oy:lle kehitetyn palvelumallin tarkoituksena on siten mallintaa investointien vaikutusta sähköverkkoliiketoiminnan valvontamallin näkökulmasta. Palvelumallissa laaditaan ennalta määritettyjen investointikohteiden ympärille optimaalinen investointiohjelma kohteiden kannattavuuden perusteella. Ohjelman perusteella voidaan puolestaan estimoida investointien vaikutusta verkosta saatavaan kohtuulliseen tuottoon ja mallintaa tämän pohjalta siirtohinnan korotuspotentiaalia. Muodostettaessa optimaalista investointiohjelmaa voidaan työssä kehitetyn laskentatyökalun avulla varioida erilaisia skenaarioita ja tehdä vaihtelevia painotuksia investointivolyymeissa vuositasolla. Laskenta seuraa myös tulorahoituksen riittävyyttä, joten investointiohjelman optimoinnilla voidaan hakea vähäisintä lisärahoitusta vaativa ratkaisu, jolloin voidaan minimoida toimitusvarmuusinvestointien aiheuttamaa vieraan pääoman kasvattamista. Osana palvelumallia päivitetään viranomaisraportointiin liittyvä toimitusvarmuuden kehittämissuunnitelma.

Volatility has a central role in various theoretical and practical applications in financial markets. These include the applications related to portfolio theory, derivatives pricing and financial risk management. Both theoretical and practical applications require good estimates and forecasts for the asset return volatility. The goal of this study is to examine the forecast performance of one of the more recent volatility measures, model-free implied volatility. Model-free implied volatility is extracted from the prices in the option markets, and it aims to provide an unbiased estimate for the market’s expectation on the future level of volatility. Since it is extracted from the option prices, model-free implied volatility should contain all the relevant information that the market participants have. Moreover, model-free implied volatility requires less restrictive assumptions than the commonly used Black-Scholes implied volatility, which means that it should be less biased estimate for the market’s expectations. Therefore, it should also be a better forecast for the future volatility. The forecast performance of model-free implied volatility is evaluated by comparing it to the forecast performance of Black-Scholes implied volatility and GARCH(1,1) forecast. Weekly forecasts for six years period were calculated for the forecasted variable, German stock market index DAX. The data consisted of price observations for DAX index options. The forecast performance was measured using econometric methods, which aimed to capture the biasedness, accuracy and the information content of the forecasts. The results of the study suggest that the forecast performance of model-free implied volatility is superior to forecast performance of GARCH(1,1) forecast. However, the results also suggest that the forecast performance of model-free implied volatility is not as good as the forecast performance of Black-Scholes implied volatility, which is against the hypotheses based on theory. The results of this study are consistent with the majority of prior research on the subject.

FTTH-liityntäverkkoja voivat rakennuttaa ja omistaa perinteisten teleoperaattoreiden lisäksi myös muut toimijat, kuten sähköyhtiöt, valtion- ja kuntien omistamat yhtiöt ja yksityiset osuuskunnat. Markkinatoimijoiden ja eri teknologioiden keskinäinen kilpailu johtaa kuitenkin helposti pieniin liityntätiheyksiin ja hajanaisiin pieniin verkkoihin. Tämä tekee verkkojen kannattavasta rakentamisesta vaikeaa ja palvelujen toteuttamisesta tehotonta. Tilannetta voidaan parantaa tasapuolisella pääsyllä, joka selkeyttää arvoketjun osapuolten rooleja. Diplomityön tavoitteena oli kuvata kommunikaatio-operaattorin rooli Suomen telemarkkinaan ja rakentaa sille taloudellisesti kannattava liiketoimintamalli toisen osapuolen toteuttamiin tasapuolisen pääsyn FTTH-verkkoihin. Työ toteutettiin hyödyntäen konstruktiivista tutkimusotetta ja sen lopputuloksena syntyi soveltuva liiketoimintamalli. Kommunikaatio-operaattorin kaksipuolisella alustalla yhdistetään valtakunnallisesti toisiinsa palveluntarjoajat ja alueellisiin liityntäverkkoihin liittyneet loppuasiakkaat. Kommunikaatio-operaattorin liiketoimintamalli mahdollistaa kapasiteetin, palvelunlaadun ja toimintavarmuuden suhteen erilaistetut virtuaaliset tukkutuotteet ja sitä kautta mahdollisuuden uuteen ansaintaan.

The 2008 global financial crisis was the consequence of the process of financialization, or the creation of massive fictitious financial wealth, that began in the 1980s, and of the hegemony of a reactionary ideology, namely, neoliberalism, based on self-regulated and efficient markets. Although capitalism is intrinsically unstable, the lessons from the stock-market crash of 1929 and the Great Depression of the 1930s were transformed into theories and institutions or regulations that led to the "30 glorious years of capitalism" (1948-1977) and that could have avoided a financial crisis as profound as the present one. It did not because a coalition of rentiers and "financists" achieved hegemony and, while deregulating the existing financial operations, refused to regulate the financial innovations that made these markets even more risky. Neoclassical economics played the role of a meta-ideology as it legitimized, mathematically and "scientifically", neoliberal ideology and deregulation. From this crisis a new capitalism will emerge, though its character is difficult to predict. It will not be financialized but the tendencies present in the 30 glorious years toward global and knowledge-based capitalism, where professionals will have more say than rentier capitalists, as well as the tendency to improve democracy by making it more social and participative, will b e resumed.

This article evaluates the effects that monetary policy actions exert on Brazilian stock market. By the measures defined to estimate the surprise caused by Comitê de Política Monetária do Banco Central do Brasil (COPOM) decisions, it was verified that to a hypothetic unexpected 1% increase in the target rate is associated an 1.3% average fall of Bovespa Index. Additional tests did not show distinct reactions caused by direction decisions, neither evidences from relevant recent economic events or decision contexts having influences on the surprise responses.

Investing in mutual funds has become more popular than ever and the amount of money invested in mutual funds registered in Finland has hit its all-time high. Mutual funds provide a relatively low-cost method for private investors to invest in stock market and achieve diversified portfolios. In finance there is always a tradeoff between risk and return, where higher expected returns can usually be achieved only by taking higher risks. Diversifying the portfolio gets rid some of the risk but systematic risk cannot be diversified away. These risks can be managed by hedging the investments with derivatives. The use of derivatives should improve the performance of the portfolios using them compared to the funds that don’t. However, previous studies have shown that the risk exposure and return performance of derivative users does not considerably differ from nonusers. The purpose of this study is to examine how the use of derivatives affects the performance of equity funds. The funds studied were 155 equity funds registered in Finland in 2013. Empirical research was done by studying the derivative use of the funds during a 6-year period between 2008–2013. The performance of the funds was studied quantitatively by using several different performance measures used in mutual fund industry; Sharpe Ratio, Treynor Ratio, Jensen's alpha, Sortino Ratio, M2 and Omega Ratio. The effect of derivative use on funds' performance was studied by using a dummy variable and comparing performance measures of derivative-users and nonusers. The differences in performance measures between the two groups were analyzed with statistical tests. The hypothesis was that funds' derivative use should improve their performance relative to the funds that don't use them. The results of this study are in line with previous studies that state that the use of derivatives does not improve mutual funds' performance. When performance was measured with Jensen's alpha, funds that did not use derivatives performed better than the ones that used them. When measured with other performance measures, the results didn’t differ between two groups.
