The Dow was up as much as 1.2% in early morning trading today before settling back down to a 0.48% by day's end. Before we get to the why, here is where the Dow and the other two major indices finished the day:

Index

Change

Ending Value

Dow Jones Industrial Average (INDEX: ^DJI) +60.01 [+0.48%] 12,482.07
Nasdaq (INDEX: ^IXIC) +17.41 [+0.64%] 2,728.08
S&P 500 (INDEX: ^GSPC) +4.58 [+0.36%] 1,293.67

Stealing the headlines from Europe, China drove the early gains. It reported higher-than-expected GDP growth for the fourth quarter: 8.9% vs. an expected 8.6%. Other favorable economic news included various stimulating actions by the Chinese government. The Chinese stock market indices themselves were up 4% to 5%.

On the negative front, banking weighed down the Dow. The KBW Bank Index (INDEX: ^BKX) was down 1.4% despite a good quarterly report from Wells Fargo. It was Citigroup's (NYSE: C) disappointing earnings that drove the banking losses. Citigroup was down 8.2% for the day and is likely to blame for the pessimism around the two biggest Dow losers: JPMorgan Chase [-2.8%] and Bank of America [-2%], which reports before the market opens on Thursday.

But beyond banking, it was a day of winners, with 23 of the 30 Dow components rising. Merck, Cisco, and United Technologies led the winners, up 1.3% each.

So it looks like Citigroup and banking in general (except Wells) had a bad day today while most of the rest of the market was up. But, as always, remember to keep all the daily (and even quarterly) noise in perspective. Invest for the long term.
