I believe there are a few pointers that are worthwhile to keep in mind when deciding if the glass is half full or half empty. In the world of economics, we have to separate between an economic slowdown and a recession. I am confident that the global economy as well most individual countries will experience an economic slowdown next year, but we are not talking about a worldwide recession. Slower growth will cause challenges for countries that need to cut their budgets and bring down unemployment, but it is not an economic disaster and the problems are well known. This brings me to the second point. In finance, it is crucial to understand what the market has already priced in. I would argue that the market has already discounted a global economic slowdown, possibly including brief recessions in the US and Eurozone, and a Greek default, coupled with problems for European banks that own the debt.
A true pessimist believes the situation will be even worse than that whereas an optimist believes we will get some kind of policy response that will ease the consequences of the economic slowdown (monetary and/or fiscal stimulus) and the financial stress (such as Central Bank liquidity, bond buying, and bank recapitalization). I am an optimist, albeit a cautious one.
