The

Securities and Exchange Commission

declared

Google's

IPO registration effective late Wednesday, clearing the way for the Net search-engine giant's pricing.

The move means that Google shares should start trading Thursday on the

Nasdaq Stock Market

.

The pricing will come at the end of a most eventful period for the closely watched deal. Google had asked the SEC to declare the IPO effective Tuesday in hopes that Nasdaq trading could begin Wednesday. But the agency, without citing any reason, took no action on the request.

Earlier Wednesday, the company dramatically scaled back the IPO, slashing its expected price range by around 25% and reducing the number of shares offered by selling shareholders.

The move seemed to bolster the case made by Google critics, who questioned everything ranging from the initial pricing range to its decision to run the IPO through an unusual Dutch auction arrangement. The repricing suggested that demand for the IPO was below the company's expectations, and that the unusual distribution system only complicated efforts to sell it.

Google now says it and its investors expect to reap around $1.9 billion by selling 20 million shares at around $85-$95 apiece.

Wednesday's action also reflects the brutal market for technology stocks. Since Google registered the offering with the SEC in late April, the Nasdaq Composite is down close to 10%, and a handful of IPOs have been delayed or withdrawn. Since the end of June, shares in Google's most direct rivals --

Yahoo!

(YHOO)

,

Amazon

(AMZN) - Get Report

and

eBay

(EBAY) - Get Report

-- have dropped between 15% and 30%.

Even so, tech stocks staged a solid rally Wednesday, with the Nasdaq rising 2% as many investor favorites bounced back from weeks of steady selling. The rise may in part reflect relief related to the end of Google IPO hand-wringing, though the stock will still be under the microscope when trading opens Thursday.
