Riesgos financieros después de la crisis subprime / Financial risks after the subprime crisis

Leiva Büchi, Rodrigo 10 April 2018 (has links)
The subprime financial crisis revealed some of risks that were not considered as a priority. Among others, a liquidityrisk is now considered as one of the main risks to work with by all institutions. Apart from that, it became obviousthat traditional risk management focused only on what was known and expected, ignoring analysis and testing eventswith low probability but high impact. Lastly, the subprime crisis left a number of lessons in relation to the regulationfor financial markets that must be considered when creating a new regulatory system. / La crisis subprime dejó al descubierto una serie de riesgos financieros que, hasta antes de la crisis, no eran consideradoscomo prioritarios. Entre otros, el riesgo de liquidez se ve ahora como uno de los principales temas a abordar por partede todas las instituciones. Adicionalmente, quedó en evidencia que la administración de riesgos se enfocaba solamenteen lo conocido y esperado, dejando de lado el análisis y evaluación de eventos de baja probabilidad de ocurrencia, peroalto impacto. Por último, la crisis subprime deja ciertas lecciones en torno a la regulación de los mercados financierosque se deben tener en cuenta al momento de redactar nuevos marcos regulatorios.

Black Swan Investments : How to manage your investments when the market is in distress

Knutsson, William, Ekeroth, David January 2020 (has links)
This study examines how investors can take advantage of Black Swan events by applying an investment strategy that involves investing in stocks that have performed badly during Black Swan events. The stocks are chosen from and compared to the Dow Jones Industrial Average Index. The purpose is to find out if the investment strategy has had a higher return than the benchmark index DJIA. The results show that the investment strategy outperforms the DJIA by 111% between the years 2000 to 2020, however, the results show no statistical significance. Beta is used as risk measurement to explain the correlation between the portfolios and the benchmark index by calculating CAPM. Standard deviation is used to calculate the Sharpe ratio and thereby assess a risk-adjusted result.

O Value at Risk e a ilusão de proteção : do risco moral ao Black Swan

Frasson, Álvaro Salgado January 2015 (has links)
A pesquisa traz uma crítica à teoria moderna de finanças em relação à política de gestão de risco, especificamente sobre o Value at Risk, e como ela afeta o risco na economia. O trabalho propõe uma discussão comportamental da ineficácia do VaR e como este tipo de informação pode ser ruim para a economia, por refletir no problema do moral hazard (risco moral) para os gestores, baseados na ilusão de compreensão, ilusão de validade e de habilidade. A dissertação conclui que,ao superestimar a informação do VaR, os agentes alteram seu comportamento para tomar decisão e, com este risco moral, podem gerar o problema dos black swans (cisnes negros). / The research brings a critique of modern finance theory in relation to risk management policy, specifically on the Value at Risk, and how this affects the risk in the economy. The paper proposes a behavioral discussion of VaR ineffectiveness and how such information may be bad in the economy, for reflecting on the moral hazard problem for managers, based on the illusion of understanding, illusion of validity and ability. The dissertation concludes that, to overestimate VaR information, the agents change their behavior to take this decision and, this moral hazard, can generate the black swans.

Accuracy of Risk Measures For Black Swan Events / Precision av Riskmått För Black Swan-Händelser

Barry, Viktor January 2021 (has links)
This project aims to analyze the risk measures Value-at-Risk and Conditional-Value-at-Risk for three stock portfolios with the purpose of evaluating each method's accuracy in modelling Black Swan events. This is achieved by utilizing a parametric approach in the form of a modified (C)VaR with a Cornish-Fisher expansion, a historic approach with a time series spanning ten years and a Markov Monte Carlo simulation modeled with a Brownian motion. From this, it is revealed that the parametric approach at the 99\%-level generates the most favorable results for a 30-day-(C)VaR estimation for each portfolio, followed by the historic approach and, lastly, the Markov Monte Carlo simulation. As such, it is concluded that the parametric approach may serve as a method of evaluating a portfolio's exposure to Black Swan events. / Denna rapport syftar till att analysera riskmåtten Value-at-Risk och Conditional-Value-at-Risk för tre aktieportföljer med målet att utvärdera respektive metods precision i att modellera Black Swan-händelser. Detta uppnås genom att utnyttja en parametrisk metod som tar formen av en modifierad (C)VaR med en Cornish-Fisher-utveckling, en historisk metod med en tidsserie som sträcker sig tio år, och en Markov Monte Carlo-simulering modellerat med en Brownian Motion. Från detta påvisas det att den parametriska metoden vid en 99\%-ig nivå genererar de mest rättvisande resultaten för en 30-dagars-(C)VaR-estimering för respektive portfölj, följt av den historiska metoden och, till sist, Monte Carlo-simulering. På så sätt dras slutsatsen att den parametriska metoden skulle kunna tjäna som en metod för att utvärdera en aktieportföljs exponering till Black Swan-händelser.
