Portfolio manager decision Brexit Coursework

Question 1. (40 Marks)

  • The referendum on Brexit took place on 23 June 2016, with the following vote to leave the European Union leading to widespread chaos and uncertainty in financial markets. After an incredible career to date, you have just started as a portfolio manager (with specific responsibility for selected investments in the banking, insurance and transport sectors) at a leading European investment bank in Dublin. The company made significant private investments in Ireland in the three sectors you are responsible for in 2015 (of approximately €2.5 billion), and they are now presenting losses in excess of 45% mainly due to Brexit uncertainty. The head office has been in contact and is threatening mass layoffs should an exit plan not be presented. Your new manager wants your opinion about the following:



  1. What are the key risks to the Irish economy in the short, medium and long term given the result of the Brexit referendum?

  1. How correlated is the Irish economy and the sectors you are responsible to the behavior of similar economic and sectorial benchmarks in the UK?

  • What financial products are available to gauge the probability of each event occurring?

  1. Did these same financial products present any evidence of the Brexit referendum passing in the weeks and months before 23 June 2016 and can they be trusted in the future?

  1. Should we accept our losses of 45% of the total portfolio or is there a chance of a recovery?What information are financial markets presenting to us?

  1. What specific steps can we take to hedge the company against immediate international contagion risk stemming from the Brexit vote and the oncoming triggering of Article 50?

  • What theoretical models are available to assist us in our immediate risk mitigation strategies?

  1. I want you to replicate their graph (also found in figure 8.1 in Bodie, Kane and Marcus, 9th edition) for any type of announcement of your choosing (eg: terrorist attacks, dividend announcements etc.).
