Certainly, part of the market's worries right now stem from oil. You still have instability in the Middle East, and there's a fear that prices will move dramatically higher.
We're in a funny space. Too much good news is not good news because the market worries about the Fed.
It doesn't look like inflation so far is accelerating. The market likes that because it worries less about the Fed raising rates too aggressively.
You've got good home sales figures showing some decent economic growth, and you've got crude oil prices up. You put those together, and that creates worries that the Fed is going to keep going on rates.
