Sentiment

One hour before the close stocks are mostly higher despite a round of mixed economic news Friday. Data released before the bell showed the Consumer Price Index (CPI) up .6% last month, which was slightly hotter than the .5% increase that economists had expected. A separate report showed December Retail Sales up .5% and .1% less than expected. The University of Michigan Sentiment Index fell to 72.7 in January, from 74.5 at the end of December and well short of expectations (75.5). On a brighter note, Industrial Production rose .8%, twice as much as expected. However, economic news is beginning to take a backseat to earnings and fourth quarter reporting gets in full swing next week. JP Morgan (NYSE: JPM) is up 2% and one of the best gainers in the Dow Jones Industrial Average after the bank reported earnings that topped estimates. The Dow is up 50 points heading into the final hour. The tech-heavy NASDAQ added 15 after Intel (NASDAQ: INTC) reported profits that topped expectations. The CBOE Volatility Index (.VIX) lost .94 to 15.45. Options action reflects the bullish underlying sentiment, with 10 million calls and 5.9 million puts traded so far.
