A look at highlights from the day's business news:
Dow inches to another 18-month high
Stocks scratched out slim gains Tuesday, pushing the Dow and S&P 500 to fresh 18-month highs and the Nasdaq to the highest point in almost two years, as economic optimism again lifted equities.
The Dow Jones industrial average added 13 points, or 0.1 percent, ending at 11,019.42, the highest point since September 26, 2008. The S&P 500 index was little changed, but nonetheless managed to end at a fresh 18-month high. The Nasdaq composite added 8 points, or 0.3 percent, ending at a new 22-month high.
Select stocks led the mild advance, with consumer and other economically sensitive shares rising. Home Depot, McDonald's, 3M and General Electric were among the Dow's bigger gainers.
But any advance was limited by weakness in financial shares, with the KBW Bank index losing 1 percent. Alcoa shares were down 3 percent, and commodity prices and shares slipped.
Dollar falls modestly after Greek debt sale
The dollar fell slightly Tuesday after Greece successfully sold $2.1 billion in sovereign debt.
What prices are doing: The dollar was 0.1 percent lower against the euro at $1.3598. It edged lower versus the U.K. pound to $1.5374. Against the Japanese yen, the dollar fell 0.1 percent to ¥93.15.
What's moving the market: The euro rallied after an auction of Greek treasury bills received strong demand. But the advance faded as investors considered the high interest rate Athens will have to pay on its debts.
Treasurys inch up during choppy stocks
Treasurys inched up Tuesday as bond investors had little economic news to go on other than a choppy stock market.
What prices are doing: The benchmark 10-year note rose 6/32 to 98-14/32, driving the yield down to 3.82 percent.
Bond prices and yields move in opposite directions. The 30-year bond rose 9/32 to 98-3/32, and its yield fell to 4.68 percent. The 2-year note was flat at 99-29/32 with a 1.06 percent yield. The 5-year note rose to 99-22/32 and yielded 2.58 percent.
What's moving the market: Stocks opened lower and then ended the day slightly up, as investors mulled over a mixed earnings report from Alcoa, the first of many major companies' quarterly earnings reports due out during the next few weeks.
Oil declines on oversupply worries
Oil prices fell Tuesday, declining for the fifth straight session as worries about oversupply weighed on the market.
What prices are doing: Crude oil for May delivery fell 29 cents to settle at $84.05 a barrel.
Prices were down as much as 2 percent during Tuesday trading and have dropped nearly 4 percent over the last five days amid mounting concerns about sluggish demand and rising supply.
