The market's three major indexes were all up today, each hitting its highest closing value in quite some time:

  Change Ending Value Highest Close Since…
Dow Jones Industrial Average (INDEX: ^DJI) +123.13 [0.96%] 12,904.08 May 2008
Nasdaq (INDEX: ^IXIC) +44.02 [1.51%] 2,959.85 December 2000
S&P 500 (INDEX: ^GSPC) +14.81 [1.10%] 1,358.04 May 2011

Big picture: The stock market has been reacting to rosier economic numbers here in the U.S.

Today's uptick was helped by the lowest initial weekly jobless claims in four years, some favorable regional manufacturing data, and last month's home construction exceeding expectations (up 10% year over year). In Europe, there is increasing hope of eurozone approval of a Greek debt-swap agreement with private bondholders to forestall a default. After-hours, the European Central Bank swapped its $65 billion in Greek bonds for new ones to protect itself (and the 17 eurozone central banks) from any losses to its own portfolio.  

The Dow
Looking to the 30 individual stocks that comprise the Dow, all but one (Kraft) gained today. The two biggest winners were Microsoft and Bank of America (NYSE: BAC), up 4.1% and 4.0%, respectively.

Microsoft continues a run that has seen it rise21% in 2012. There didn't seem to be much major news reported, but it saw the most trading activity today of any Nasdaq-listed stock.

Bank of America is more tied to investor impressions of the economy, so its big gain on an up day isn't as surprising. It has been the most actively traded stock in the market (read John Maxfield's explanation here) and today was another large-volume day. For the year, it's up 45.5%.  

Outside of the Dow, former Dow component GM (NYSE: GM) blazed up 9% after reporting its eighth straight quarter of profitability and a record-breaking $7.6 billion earnings haul for 2011 as a whole.
