A stronger than expected durable goods report and another day of gains in battered mortgage stocks had investors in a good mood on Wednesday.

Technology investors are hoping the good mood carries over into Thursday night, when Dell (NASDAQ: DELL) will report its quarterly results.

Investors and analysts will be looking for signs that the company is continuing its turnaround. Analysts are looking for an 8% increase in sales to $15.95 billion and earnings of 36 cents a share, according to Thomson Financial.

Dell shares have gained 40% since setting a low of $18.13 in April and closed today at $25.63, up 1.8%. The company's shares have benefited from a blow-out April quarter, and investors will be watching closely to see if the tech bellwether can continue to weather the economic headwinds.

The major indexes gained 0.8% Wednesday on a 1.3% jump in durable orders last month and another day of double-digit percentage gains in Freddie Mac (NYSE: FRE) and Fannie Mae (NYSE: FNM).

But Sun (NASDAQ: JAVA) fell 7% on an IDC report that said the company is losing server market share.

SI International (NASDAQ: SINT) soared 36% on a buyout offer.

Applied Signal (NASDAQ: APSG) jumped 7% on its results.
