A deal to secure 130 billion euros ($172 billion) to prevent the sovereign nation from defaulting on its debt in late March (when the next tranche is due) was reached. In return, creditors will accept a 53.5% write-down on their debt and a reduction in the interest rate paid on 56 billion euros in loans from the prior bailout. This will reduce the ratio of debt to GDP of the country to 120% by 2020. This news originally led to a 1.2% pop in the Euro Stoxx 50 index, which measures the performance of 50 stocks in 12 eurozone countries, but the index ended up declining. The worries follow concerns that the agreed-upon austerity measures that are to be implemented in order to receive the payment could be reversed to some degree after elections are held in Greece. The election is slated to take place in two months. According recent polls, leftist parties opposing the bailouts are rising in popularity. Wayne Lin, portfolio manager and investment strategy analyst for Legg Mason ( LM) Global Asset Allocation, says investors should watch the election carefully and manage their portfolios accordingly. U.S. investors have become comfortable with the situation in Europe, especially as our own economy is showing an improvement. However, volatility could increase substantially if the incoming government plans to reduce austerity measures, putting the stability of Greece's debt position in jeopardy of default. Talks of exiting the euro would also lead to uncertainty and increased volatility. As the election evolves over the next few months, U.S. investors should actively manage their market positions. Lin recommends taking some money out of risky assets if one of these scenarios becomes likely. He points out that risk premiums reached historic highs in August and if equities were to approach those levels again, that would signal a good exit point.
