One of the stock market's most perplexing moves for both professional and retail investors is when the market, best represented by the S&P 500, moves in a direction that might be contrary to current conditions regarding economic growth.
This is one of the most difficult concepts to understand; that the S&P 500 does not represent current economic growth conditions, but what the market believes is highly probable for the future.
We have recently witnessed a substantial move upward in the S&P 500, yet only recently have we seen some positive signs that economic growth may be slightly improving. I stress "slightly," because no one really expects economic growth for 2013 to be massive.
While jobs growth has been relatively weak, there have been some signs that suggest economic growth is resuming. However, with much of the data, there can be quite a lot of noise that can distort the underlying strength or weakness of economic growth.
