  1. 1. Chasing Your Own Tail: The Market Stability Impact of Leveraged and Inverse Exchange-Traded Funds

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Författare :Gustaf Gustafsson; Sebastian Gerell; [2020]
    Nyckelord :Leveraged ETFs; Financial Stability; Market Microstructure Invariance; Price Impact; Sweden;

    Sammanfattning : This thesis explores the market stability impact of the positive feedback mechanism of leveraged and inverse exchange-traded funds' (LETFs) rebalancing trades. We explore potential market stability effects by analysing intraday minute-by-minute data for underlying stocks in the OMXS30 and aggregate rebalancing flows for LETFs tracking the index. LÄS MER

  3. 2. DATA-DRIVEN DYNAMIC CAPABILITIES An exploration into digital transformation and business strategy building entailed by a dynamic capabilities view

    Kandidat-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Författare :Andreas Marttila Gaard; Martin Malmgren; [2020]
    Nyckelord :dynamic capabilities; digital transformation; business model innovation; business strategy; data driven;

    Sammanfattning : The pervasive nature of technological advancements has increased the complexity, and thus the environmental volatility that span well across the borders of industries and na-tions. It could be argued that the need for firms to demonstrate dynamic capabilities are greater than ever before. LÄS MER

  4. 3. A Study of a New-Keynesian DSGE Macro Model: Estimates, Shocks, and Optimal Monetary Policy

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Erik Hjort; [2019]
    Nyckelord :New-Keynesian Economics; Rational Expectations; Monetary Policy; Aggregate Shocks; Small-scale DSGE Model; Business and Economics;

    Sammanfattning : This paper estimates and simulates a New-Keynesian small-scale DSGE macro model. The model consists of the hybrid forms of the Phillips curve and the IS curve, and is closed with a Taylor-type feedback rule allowing partial adjustment of the monetary policy instrument. LÄS MER

  5. 4. Particle-based Stochastic Volatility in Mean model

    Master-uppsats, KTH/Matematisk statistik

    Författare :Gustav Kövamees; [2019]
    Nyckelord :Stochastic volatility model; Volatility feedback theory; hidden Markov model; particle filter; Expectation-Maximization algorithm; PaRIS-algorithm; Stokastisk volatilitets modell; dold Markov modell; partikel-filter; Förväntan-Maximering algorithm; PaRIS-algoritm; volatilitets-återkopplings-teori;

    Sammanfattning : This thesis present a Stochastic Volatility in Mean (SVM) model which is estimated using sequential Monte Carlo methods. The SVM model was first introduced by Koopman and provides an opportunity to study the intertemporal relationship between stock returns and their volatility through inclusion of volatility itself as an explanatory variable in the mean-equation.

  7. 5. Optimal portfolio allocation by the martingale method in an incomplete and partially observable market

    Master-uppsats, KTH/Matematisk statistik

    Författare :Emil Karlsson; [2016]
    Nyckelord :;

    Sammanfattning : In this thesis, we consider an agent who wants to maximize his expected utility of his terminal wealth with respect to the power utility by the martingale method. The assets that the agent can allocate his capital to are assumed to follow a stochastic differential equation and exhibits stochastic volatility. LÄS MER
