Sometimes it helps to make a list of issues and hopefully start to check them off. Unfortunately the list has been getting longer, and some of the downside risks will be with us for some time:
-Risks from the earthquake in Japan.
-Higher oil prices and a possible supply shock.
-U.S. Housing Crisis.
-The European financial crisis.
-State and local government cutbacks.
-Possible Federal government cutbacks (even shutdown).
-Inflation (a two sided coin).
