The determination of EONIA rate: The impact of the financial crisis and the effects of the changes in the monetary policy implementation framework

EONIA is a market based overnight interest rate, whose role as the starting point of the yield curve makes it critical from the perspective of the implementation of European Central Bank´s common monetary policy in the euro area. The financial crisis that started in 2007 had a large impact on the determination mechanism of this interest rate, which is considered as the central bank´s operational target. This thesis examines the monetary policy implementation framework of the European Central Bank and changes made to it. Furthermore, we discuss the development of the recent turmoil in the money market. EONIA rate is modelled by means of a regression equation using variables related to liquidity conditions, refinancing need, auction results and calendar effects. Conditional volatility is captured by an EGARCH model, and autocorrelation is taken into account by employing an autoregressive structure. The results highlight how the tensions in the initial stage of the market turmoil were successfully countered by ECB´s liquidity policy. The subsequent response of EONIA to liquidity conditions under the full allotment liquidity provision procedure adopted after the demise of Lehman Brothers is also established. A clear distinction in the behavior of the interest rate between the sub-periods was evident. In the light of the results obtained, some of the challenges posed by the exit-strategy implementation will be addressed.

Determinants of credit default swap spread, the effect of the financial crisis in the us markets

The purpose of this study is to define what determinants affect the Credit spread. There are two theoretical frameworks to study this: structural models and reduced form models. Structural models indicate that the main determinants are company leverage, volatility and risk-free interest rate, and other market and firm-specific variables. The purpose is to determine which of these theoretical determinants can explain the CDS spread and also how these theoretical determinants are affected by the financial crisis in 2007. The data is collected from 30 companies in the US Markets, mainly S&P Large Cap. The sample time-frame is 31.1.2004 – 31.12.2009. Empirical studies indicate that structural models can explain the CDS spreads well. Also, there were significant differences between bear and bull markets. The main determinants explaining CDS spreads were leverage and volatility. The other determinants were significant, depending on the sample period. However, these other variables did not explain the spread consistently.

Is it possible to utilize VIX for a profitable trading strategy of S&P 500 Index?

The goal of this research was to make an overall sight to VIX® and how it can be used as a stock market indicator. Volatility index often referred as the fear index, measures how much it costs for investor to protect his/her S&P 500 position from fluctuations with options. Over the relatively short history of VIX it has been a successful timing coordinator and it has given incremental information about the market state adding its own psychological view of the amount of fear and greed. Correctly utilized VIX information gives a considerable advantage in timing market actions. In this paper we test how VIX works as a leading indicator of broad stock market index such as S&P 500 (SPX). The purpose of this paper is to find a working way to interpret VIX. The various tests are made on time series data ranging from the year 1990 to the year 2010. The 10-day simple moving average strategy gave significant profits from the whole time when VIX data is available. Strategy was able to utilize the increases of SPX in example portfolio value and was able to step aside when SPX was declining. At the times when portfolio was aside of S it was on safety fund like on treasury bills getting an annual yield of 3 percent. On the other side just a static number’s of VIX did not work as indicators in a profit making way.

Tukkusähkön hintapiikkeihin reagoinnin keinot sellu- ja kartonkitehtaalla.

Sähkön tukkuhinnat vaihtelivat hyvin voimakkaasti talvella 2009–2010. Työssä on esitetty rajahyötytarkasteluna yhdistetyn sellu- ja paperitehtaan mahdollisuudet lisätä vastapainesähkön tuotantoa sekä leikata sähkön kulutusta aikana, jolloin sähkön tuntihinta on korkea. Työssä tarkastellaan myös erilaisia sähkömarkkinaoperaatioita. Työn ensimmäisessä osiossa esitellään Stora Enson Imatran tehtaat. Myöhemmissä kappaleissa perehdytään pohjoismaisten sähkömarkkinoiden sekä kaasupörssin toimintaan. Jotta korkeista sähkön hinnoista voitaisiin hyötyä, tulee sähkön myyntitarjoukset jättää sähköpörssi Nord Poolin kaupankäyntijärjestelmään toimitusvuorokautta edeltävänä päivänä. Tässä työssä on määritetty sähköenergian mahdolliset myyntivolyymit sekä hinnat eri tuotantotilanteissa. Työssä pyritään parantamaan tehtaan sähkökaupankäynnin kannattavuutta käyttämällä eri sähkökaupan tuotteita. Työssä esitetään malleja, joiden avulla korkeita sähkön markkinahintoja voidaan pyrkiä hyödyntämään. Eri sähkömarkkinatuotteet soveltuvat myös riskienhallintaan voimakkaasti vaihtelevilla sähkömarkkinoilla

Teknisen analyysin hyödynnettävyys hyödykefutuurimarkkinoilla

Tutkielman tavoitteena on tarkastella teknisen analyysin hyödynnettävyyttä hyödykefutuurimarkkinoilla. Tutkielmassa pyritään selvittämään, onko teknisen analyysin eri menetelmien mukaan ajoitetuilla hyödykefutuurien osto- ja myyntitoimeksiannoilla mahdollista ylittää toisaalta passiivisen indeksisijoittamisen ja toisaalta osta ja pidä -strategian tuottotaso sekä työssä analysoimaan saatujen tulosten syitä. Tutkimusaineisto sisältää 25 eri hyödykkeen futuuriaikasarjat vuosilta 2000 - 2010. Historiallisiin kurssitietoihin pohjautuen muodostettiin seitsemän sijoitusstrategiaa ja yhteensä 21 eri menetelmävariaatiota, joiden suoriutumista tutkittiin yksittäisten hyödykefutuurien osalta sekä hyödykefutuuriportfolioina. Tulokset osoittivat, että tekniseen analyysiin perustuvilla hyödykefutuuri-strategioilla on ollut mahdollista saavuttaa merkittävää hajautushyötyä. Lisäksi aktiivisten kaupankäynti¬strategioiden tuotot ylittivät sekä passiivis-ten markkinaindeksien että osta ja pidä -strategian tuottotason. Strategioi-den kannattavuuden havaittiin korreloivan positiivisesti ja tilastollisesti merkitsevästi tutkimuksessa analysoitujen tuottoaikasarjojen autokorreloituneisuusasteen kanssa, mutta käänteisesti ja merkitsevästi eri menetelmävariaatioiden synnyttämien kaupankäynti¬signaalien määrän kanssa.

Innovaatio-ohjelmatoiminnan suorituskyvyn mittaus

Tutkimuksen tavoitteena on luoda viitekehys yritysten innovaatiotoimintaa ohjelmatoiminnalla tukevan julkisen organisaation suorituskyvyn mittaamiseksi. Tutkimus on luonteeltaan tapaustutkimus ja tutkimusotteena siinä käytetään toiminta-analyyttistä tutkimusotetta. Tutkimuksen empiirinen aineisto kerättiin havainnoimalla, keskusteluilla, haastatteluilla sekä ryhmätyöskentely-menetelmillä. Luodun viitekehyksen mukaan innovaatiotoimintaa ohjelmatoiminnalla tukevan julkisen organisaation tuottama julkinen arvo syntyy pienentämällä innovaatio-toiminnan markkina- ja järjestelmähäiriöitä, joka tapahtuu tarjoamalla rahalista tukea sekä palveluita. Näin innovaatiotoiminnan tuloksellisuus ja positiiviset ulkoisvaikutukset lisääntyvät. Tämä johtaa lopulta talouden kasvamiseen sekä yhteiskunnan ja ympäristön hyvinvointiin. Innovaatiotuella voidaan säädellä myös innovaatiotoiminnan aluetta ja näin luoda arvoa pureutumalla yhteiskunnan ongelmakohtiin. Tämän lisäksi kansalaisille on todennäköisesti arvokasta organisaatiota kohtaan tuntema luottamus, jota kasvattavat luultavasti esimerkiksi resurssien tehokas käyttö, oikeudenmukainen toiminta, asiakkaiden yhden-mukainen kohtelu, todennetut tulokset ja vaikutukset sekä toiminnan läpinäkyvyys. Viitekehyksen pohjalta muodostettiin Ohjelmat-ydinprosessin suorituskyvyn mittaristo. Aluksi kuvattiin ydinprosessin tavoitteet, joita tarkennettiin vaikuttavuusmallilla sekä sidosryhmäanalyysillä. Seuraavaksi muodostettiin ydinprosessille strategiakartta ja tunnistettiin sen kriittiset menestystekijät. Tuloksena syntyi mittaristo, jossa on 84 potentiaalista prosessin suorituskykyä mittaavaa mittaria. Lopuksi mittaristoa tarkasteltiin kokonaisuutena ja todettiin se kohtalaisen hyvin onnistuneeksi.

Added Value of Combining Value and Momentum Indicators in the Swiss Stock Market

The purpose of the thesis is to examine the added value of combining value and momentum indicators in the Swiss stock exchange. Value indicators employed are P/E, EV/EBITDA, P/CF, P/B ja P/S. Momentum indicators examined are 52-week high, acceleration rate, 12-month past return and 6-month past return. The thesis examines whether the composite value measures based on the above mentioned ratios can add value and whether the inclusion of momentum can further improve the risk return profile of the value portfolios. The data is gathered from the Swiss equity market during the sample period from May 2001 to May 2011. Previous studies have shown that composite value measures can somewhat add value to the value portfolio strategy. Similarly, recent academic literature have found evidence that momentum works well as a timing indicator for time to entry to value stocks. This study indicates that the added value of composite value measures exists. It also shows that momentum combined to acceleration rate can significantly improve the risk adjusted performance of value-only portfolios.

Sähkön hinta pohjoismaisilla sähkömarkkinoilla

Kandidaatintyössä käsitellään sähkön tukkuhintaa pohjoismaisilla sähkömarkkinoilla. Työn tavoitteena on selvittää kuinka sähkön hinta määräytyy markkinoilla, mitkä tekijät siihen vaikuttavat sekä kuinka hinta on kehittynyt. Lisäksi tavoitteena on arvioida markkinoiden kehitysnäkymiä. Sähkön hinnalle on ominaista suuri vaihtelu, mikä tekee markkinoista hyvin haasteelliset. Suuren hinnanvaihtelun ja sen ennalta arvaamattomuuden vuoksi markkinoilla toimivilla osapuolilla on toiminnassaan merkittäviä riskejä. Riskien ymmärtäminen ja niiltä suojautuminen on markkinoilla toimimisen edellytys. Sähkön hinta on selvästi noussut vuodesta 1999 vuoteen 2011. Tulevaisuudessa sähkön hinnan arvioimisessa oleellista on sähkön hintaan vaikuttavien tekijöiden kehitys. Markkinoiden kehityssuuntauksilla ja yleisellä maailmantalouden kehityksellä voi olla ratkaiseva vaikutus sähkön hinnan kehitykseen.

Management of commercial property derived risks in the market context of the Russian Federation

The objective of the thesis is to examine the current state of risk management and to determine an appropriate risk management policy for commercial property derived risks in the Russian branch of a Finnish retail trade company. The employed research methodologies are comparative in-depth interviews and empirical value at risk analysis, including portfolio risk decomposition to determine the inter-currency characteristics. For a multinational retail trade company, the commercial property derived risks open up as a diverse combination of financial and non-financial risks with four distinctive interest groups. The research results indicate that geographical diversification across currency regimes provides diversification benefits. The Russian ruble is the most significant single risk component when considering the net investments outside the euro-zone. Decreasing the Russian ruble and Swedish krona exposures are the most effective methods to reduce translation derived risk. Exchange rate volatility varies over time according to idiosyncratic currency regime characteristics, and cost-effective risk management requires comprehensive analysis of the business environment. Profound and proactive risk management methods are found to be pivotal for companies with cross-border operations in order to succeed among international competitors.

Elintarvikkeiden saatavuuden varmistamisen keinot ja ostotilausprosessin kehittäminen tukkuliikkeessä

Työn tavoitteena oli selvittää, miten elintarviketukun suurtaloustuotteiden saatavuus voitaisiin varmistaa. Nykyisellään suurtalouselintarvikkeiden kysynnän vaihtelut ovat vaikeasti hallittavia, mikä nostaa niiden varastotasoja aiheuttaen ongelmia kohdeyrityksen ahtaaksi käyneessä varastossa. Lisäksi tuotteiden tilaaminen työllistää neljä henkilöä ja mahdollinen tilausmäärien kasvu lisäisi henkilöstötarvetta entisestään. Työn tuloksena yrityksen tuotteet sekä toimittajat jaettiin neljään eri ryhmään: paras a-ryhmä, haasteryhmä, testiryhmä ja poistoryhmä. Näiden ryhmien varastojen ja tilausten hallitsemiseksi esitettiin puolestaan kolme eri tapaa: Automaattiset ostotilaukset sopivat kaikille tasaisen kysynnän tuotteille. Suuren kysynnän vaihtelun tuotteille voidaan käyttää nykyistä tilaustapaa sekä hyödyntää mahdollisuuksien mukaan asiakkailta saatavia menekkiennusteita tilaamisen tukena. Ongelmallisten suuren kysynnän vaihtelun ja pienen menekin tuotteiden kohdalla tuot-teet voidaan joko poistaa kokonaan yrityksen valikoimasta tai niiden tilaaminen voidaan muuttaa varasto-ohjauksen sijaan tilausohjautuvaksi.

Observations of Industry Momentum Effect in European Equity Indices

This thesis examines the existence and nature of momentum effect in European equity indices. A set of predefined indicators is used to compose momentum portfolios and different holding periods are used to test the strategies over variable time periods as well as under different economical conditions. The data consists of daily closing prices of STOXX Europe 600 index and its 18 super sector indices. Over the study period we follow the performances of a long position in the Winner portfolio, a position in the market neutral zero-cost portfolio and also a position in the risk-controlled zero-cost portfolio. The investment ratio of the risk-controlled zero-cost portfolio is negatively correlated with the realized market volatility. The results show that momentum effect is present in European industries and is most prominent in the short-term. Indicators that are based on short-term performance tend predict the over- and underperformers for the 1-month holding period more reliably than any other indicator/holding period combination. The examination of the strategies under different economical conditions shows that the market neutral approach can create significant returns in times of recession but in times of economic boom the long position in Winner portfolio outperforms the market neutral portfolio by an extensive margin.

Pricing anomalies in the Finnish stock market

The aim of this thesis is to examine whether the pricing anomalies exists in the Finnish stock markets by comparing the performance of quantile portfolios that are formed on the basis of either individual valuation ratios, composite value measures or combined value and momentum indicators. All the research papers included in the thesis show evidence of value anomalies in the Finnish stock markets. In the first paper, the sample of stocks over the 1991-2006 period is divided into quintile portfolios based on four individual valuation ratios (i.e., E/P, EBITDA/EV, B/P, and S/P) and three hybrids of them (i.e. composite value measures). The results show the superiority of composite value measures as selection criterion for value stocks, particularly when EBITDA/EV is employed as earnings multiple. The main focus of the second paper is on the impact of the holding period length on performance of value strategies. As an extension to the first paper, two more individual ratios (i.e. CF/P and D/P) are included in the comparative analysis. The sample of stocks over 1993- 2008 period is divided into tercile portfolios based on six individual valuation ratios and three hybrids of them. The use of either dividend yield criterion or one of three composite value measures being examined results in best value portfolio performance according to all performance metrics used. Parallel to the findings of many international studies, our results from performance comparisons indicate that for the sample data employed, the yearly reformation of portfolios is not necessarily optimal in order to maximally gain from the value premium. Instead, the value investor may extend his holding period up to 5 years without any decrease in long-term portfolio performance. The same holds also for the results of the third paper that examines the applicability of data envelopment analysis (DEA) method in discriminating the undervalued stocks from overvalued ones. The fourth paper examines the added value of combining price momentum with various value strategies. Taking account of the price momentum improves the performance of value portfolios in most cases. The performance improvement is greatest for value portfolios that are formed on the basis of the 3-composite value measure which consists of D/P, B/P and EBITDA/EV ratios. The risk-adjusted performance can be enhanced further by following 130/30 long-short strategy in which the long position of value winner stocks is leveraged by 30 percentages while simultaneously selling short glamour loser stocks by the same amount. Average return of the long-short position proved to be more than double stock market average coupled with the volatility decrease. The fifth paper offers a new approach to combine value and momentum indicators into a single portfolio-formation criterion using different variants of DEA models. The results throughout the 1994-2010 sample period shows that the top-tercile portfolios outperform both the market portfolio and the corresponding bottom-tercile portfolios. In addition, the middle-tercile portfolios also outperform the comparable bottom-tercile portfolios when DEA models are used as a basis for stock classification criteria. To my knowledge, such strong performance differences have not been reported in earlier peer-reviewed studies that have employed the comparable quantile approach of dividing stocks into portfolios. Consistently with the previous literature, the division of the full sample period into bullish and bearish periods reveals that the top-quantile DEA portfolios lose far less of their value during the bearish conditions than do the corresponding bottom portfolios. The sixth paper extends the sample period employed in the fourth paper by one year (i.e. 1993- 2009) covering also the first years of the recent financial crisis. It contributes to the fourth paper by examining the impact of the stock market conditions on the main results. Consistently with the fifth paper, value portfolios lose much less of their value during bearish conditions than do stocks on average. The inclusion of a momentum criterion somewhat adds value to an investor during bullish conditions, but this added value turns to negative during bearish conditions. During bear market periods some of the value loser portfolios perform even better than their value winner counterparts. Furthermore, the results show that the recent financial crisis has reduced the added value of using combinations of momentum and value indicators as portfolio formation criteria. However, since the stock markets have historically been bullish more often than bearish, the combination of the value and momentum criteria has paid off to the investor despite the fact that its added value during bearish periods is negative, on an average.

Hedge-rahastojen menestyksen pysyvyyden empiirinen tarkastelu sijoittajan näkökulmasta

This study examines performance persistence of hedge funds from investor's point of view and look at the methods by which an investor could choose the successful hedge funds to the portfolio. This study was used the data from HFI & Tremont databases on period 1998-2007. In this study used the 36-month combination (24-month selection and 12-month prediction periods). As the research methods used the Sharpe index, raw returns, MVR (mean variance ratio), GSC-clustering, the SDI index and the new combination of metrics. The evaluation criterions of the results used the volatility, excess returns and the Sharpe index. This study compared different results from the 7 time series with each other, and commenting the problems on a portfolio loss of funds.

The Use of Systematic Value Strategies in Separating the Winners from the Losers: Evidence from the Finnish Markets

This study examines the Magic Formula and ERP5 value strategies in the Finnish stocks markets. Magic Formula ranks stocks based on EV/EBIT and ROA and ERP5 based on EV/EBIT, ROA, P/B and five-year trailing ROA. The purpose of the study is to examine whether the value strategies can be used to generate excess returns over the market index. The data has been collected from the Datastream database for the sample period from May 1997 to May 2010 and consists of the companies listed on the main list of Helsinki Stock Exchange. This study confirms the findings of previous research that value premium exists in the Finnish stock markets and that systematic value strategies can be used to form portfolios that outperform the market index with lower volatility.

Diversification benefits for a Finnish non-industrial private forest investor: Real Estate Investment Trusts in the USA

This thesis examined both domestic and international forest investment options for a Finnish non-industrial private forest investor. The focus was on forest-based investment instruments. The influence of movements of currency exchange rates on foreign returns were also taken into account. Annual data from 1995 to 2011 was used. The main portfolio optimization model in this study was the Mean-Variance model but the results were also validated by using the Value at Risk and Expected Shortfall models. In addition, the exchange rate risk hedging was established by using one-week-maturity forward contracts. The results suggested that 75 % of the total wealth should be invested in Finnish private forests and the rest, 25 %, to a US REIT, in this case Rayonier. With hedging, the total return on the portfolio was 7.21 % (NIPF 5.3%) with the volatility of 6.63 % (NIPF 7.9%). Taxation supported US investments in this case. As a conclusion, a Finnish private forest investor may, as evidenced, benefit in diversifying a portfolio using REITs in the US.
