Of course this data is for January and much has happened since then. It certainly does appear either the economy has truly started to pick up or anticipated euphoria is at least moving the stock market forward.
One item I would watch closely however is consumer credit. While sales may be picking up in February and March (numbers next month will show us if this is a trend as I anticipate it will be) we are seeing a large growth in consumer credit again (7% growth in January as reported by the Federal Reserve). This means the consumer, for the most part, is starting to leverage again and we all know this cannot sustain itself. The recession caused the consumer to "de-leverage" a lot and now it appears the consumer is back to being willing to leverage themselves.
Beware the borrowing!
