Today was a mixed bag. Shares spent most of the day in the red but staged a late day rally. Oil prices remained under $110 per barrel, which pulled down energy and commodity stocks yet again. Even the brief relief in today's Beige Book from the Federal Reserve hardly helped the situation despite it starting to see some energy price relief. The good news is that shares came back up in the last hour, masking some of the intra-day selling.

Here are today's unofficial closing bell levels:
DJIA 11536.87 (+19.95)
S&P500 (1275.35 (-2.22)
NASDAQ 2334.74 (-14.50)
10YR T-Note 3.697% (-0.049%)
