Stocks were showing life early Wednesday as positive results from Amazon ( AMZN - Get Report) and several other bellwether companies looked poised to jumpstart the recently moribund technology sector.

Index futures recently showed both the S&P 500 and Nasdaq 100 trading about 3 points above fair value. The 10-year Treasury bond was down 2/32 in price to yield 4.08%, while the dollar rose against the yen and euro. June crude, which has lost 3% since topping out above $75 a barrel Friday, was recently up 9 cents to $72.97.

WellPoint ( WLP) kicked off the earnings cascade, saying its first-quarter profit rose 20% to $731.8 million, or $1.09 a share. The health insurer beat on the bottom line, although sales of $13.61 billion were slightly light.

Another big story early Wednesday involves chemical company Engelhard ( EC - Get Report), which detailed a plan to repurchase about 20% of its stock at a 17% premium to the market price. The buyback will be financed with debt and is intended to counter a hostile takeover offer made three months ago by Germany's BASF.

Two economic reports could shape trading Wednesday. At 8:30 a.m. EDT, the Commerce Department is expected to say durable good orders rose 1.8% in March, and at 10 a.m. the same agency will probably say new homes sold at an annual rate of 1.1 million units last month.

A buoyant reading on existing home sales Tuesday raised concerns about the future of Federal Reserve interest-rate policy and sent major stock indices lower, with the Nasdaq falling for the fourth straight session. For the day, the Dow and S&P 500 lost 0.4%, while the Nasdaq lost 0.1%.

Amazon rose late Tuesday after reporting a 35% decline in first-quarter earnings to $51 million, or 12 cents a share, reflecting a gain in the year-ago period. The results, which included a 20% gain in sales to $2.28 billion, matched estimates, and the company boosted revenue guidance for the full year.

Several other companies that are sometimes viewed as proxies for the tech economy had solid results. Wholesaler Ingram Micro ( IM) said first-quarter earnings rose 45% from a year ago on an 8% rise in sales, beating estimates.

Electronics contractor Sanmina ( SANM - Get Report) saw its shares surge on a sharply narrowed second-quarter loss and strong guidance. The company sees sales of $2.7 billion to $2.8 billion in the coming quarter.

RF Micro ( RFMD) also posted a narrowed quarterly loss and said sales surged 50% on strong demand for its cellphone chips. The company guided to a better-than-expected earnings and sales in the current period.

The earnings parade marches on Wednesday, with reports expected from Anheuser-Busch ( BUD), Zimmer Holdings ( ZMN) and ConocoPhillips ( COP - Get Report).
