Stocks were set for a higher open Friday as Wall Street tried to regain its footing after a two-day selloff.

Futures on the

S&P 500

were up 2 points to 1309.60, about 5 points above fair value. Nasdaq 100 futures were adding a quarter-point to 1587 and were roughly 3 points ahead of fair value.

On Thursday, the

Dow Jones Industrial Average

lost 75 points, or 0.7%, and the S&P fell 6 points, or 0.5%. The

Nasdaq Composite

gave back more than 12, or 0.6%. Those declines came a day after worries about the economy drove the Dow down 63 points, the S&P lower by 13 points, and the Nasdaq to a loss of nearly 38 points.

The market was set to rise even as another homebuilder lowered its guidance, this time

Lennar

(LEN) - Get Report

. Already this week,

Beazer Homes

(BZH) - Get Report

and

KB Homes

(KBH) - Get Report

have issued warnings.

Elsewhere,

Broadcom

(BRCM)

said it found more stock option irregularities, and the wireless chip company now expects its planned restatement to total at least $1.5 billion.

After the close Thursday,

National Semiconductor

(NSM)

said sluggish sales were the reason it missed its first-quarter financial goals and indicated that the weakness is continuing in the current quarter.

Shareholders of both

Lucent

(LU)

and

Alcatel

(ALA)

have voted in favor of the merger of the telecom-equipment providers. However, Lucent's holders weren't very enthusiastic, as just more than half gave their support.

The economic calendar is almost bare, with just a report on consumer credit from the

Federal Reserve

on the schedule.
