Why Are Investors Pricing In A Slowdown?

The Bureau of Economic Analysis (BEA) surprised even the most optimistic of economists when it reported the U.S. economy grew at an annual rate of four percent in the second quarter of 2014.

On the surface, the number -- four percent growth -- sounds great. But how serious should we take that gross domestic product (GDP) figure?

First, it's important to remember that the BEA often revises its GDP numbers down. We saw it in the first quarter when the BEA said that the U.S. economy grew by 0.1% in the first quarter. Then after a couple of revisions, they said the economy actually contracted by 2.9% in the quarter.

I obviously expect the BEA to lower its initial second-quarter GDP numbers again.

But here’s what really worries me: If GDP data suggests the U.S. economy is growing, why are investors pricing in an economic slowdown?

The chart below is of the 10-Year U.S. Treasury -- the so-called 'safe-haven' bond. As the U.S. economy improved, the yields on the 10-year U.S. Treasury started to rise as interest rates rose with general optimism toward the economy.
