Investors got a lot of good news this morning, which helped push the markets higher today. The Dow Jones Industrial Average (DJINDICES:^DJI) rose by 152 points, or 1.05%, and closed at 14,719. The S&P 500 fared just slightly worse, gaining 1.04%, while the Nasdaq was the big winner today, after it climbed higher by 1.11%.

In addition to a number of positive earnings reports that came out before the market opened, the new-home sales report helped reinforce investors' confidence that the economy is strengthening. The Commerce Department said that new-home sales increased by 1.5% to a seasonally adjusted rate of 417,000 homes. Analysts were expecting 420,000 units, so the results were in line with expectations.

Two of the companies that announced earnings were Travelers (NYSE:TRV) and DuPont (NYSE:DD), whose shares rose by 2.09% and 4.13%, respectively, after both reported better-than-expected earnings for the first quarter.

Travelers reported $2.33 per share in earnings, while analysts were expecting only $2.02. Revenue also beat expectations, coming in at $6.33 billion, while analysts had been estimating only $6.23 billion in sales. The company noted that a drop in natural disaster claims in addition to higher premiums during the quarter allowed the company to outpace expectations, leading to an 11% year-over-year gain in earnings. In addition, Travelers raised its quarterly dividend by 9% to $0.50 per share.

DuPont also announced a dividend increase, which amounts to a 5% increase, and the company beat on the bottom line, while meeting expectations on the top line. Earnings were expected to hit $1.52 per share on revenue of $10.41 billion, but the company managed to stretch that amount of revenue to EPS of $1.56. DuPont also reaffirmed its previous full-year earnings guidance of $3.85 to $4.05 per share, an increase of 2% to 7% over what the company posted for 2012.
