The late players were out scouting the extended platforms tonight, which looked evenly divided between the hues of both red and green. And investors departed from the usual big-cap tech stocks and shared the spotlight with some lesser-known outfits tonight as well.

Kicking off pre-announcement season,

Sawtek

(SAWS)

, a wireless equipment and parts maker, fell 8.7% to $25.80 on

Instinet

and 8.4% to $25.89 on

Island

ECN after the company projected lower-than-expected third-quarter earnings, citing the crunch in the wireless communication sector.

TriQuint Semiconductor

(TQNT)

, which announced recently it would acquire Sawtek in a stock deal worth about $1.3 billion, was suffering tonight. On Instinet, the shares slipped 8.0% to $22.82, while on Island, they fell 7.7% to $22.90.

Blue-chip

General Electric

(GE) - Get Report

was lately atop the Instinet volume list, though its shares were unchanged at $51.35. Headwaters

(HDWR)

, an alternative fuel company whose patented binding process that turns coal derivatives into synthetic fuel briquettes, was the most heavily traded stock on Island, slipping 1.1% to $12.53.

Drug giant

Pfizer

(PFE) - Get Report

was sitting in the number two spot on Instinet's list, its price unchanged.

Prudential Securities'

Tim Anderson initiated coverage on Pfizer today with a strong buy rating and a price target of $55.

In the red tonight,

Genome Therapeutics

(GENE) - Get Report

lost 1.0% to $13.36 on Island following its stellar 50% gain to $13.50 on the Nasdaq during regular trading. The shares were lifted after a favorable research report by an analyst from

Ladenburg Thalmann

, which rated its shares a strong buy and predicted the company's expertise will "lead to the discovery of several anti-infective agents with markets approaching $1 billion."

And trouble seemed to be brewing for oil and gas research company

Emex

(EMEX)

, which tumbled 41.3% to $15.50 on Instinet, before getting halted by

Nasdaq, pending some news from the company. Shares of Emex, which is working to develop fuel cell technology for manufacturing electricity and clean fuels from natural gas, closed at $26.40 on the tech-heavy Comp.

But

J.D. Edwards

(JDEC)

gained 6.4% to $12.69 on Island with its earnings numbers tonight. In a conference call, the company said it sees 2001 earnings at the upper range of its latest guidance. On March 5, the enterprise and supply chain software maker said it would earn 20 to 25 cents for 2001, higher than the 13 cents a share estimate compiled by earnings tracker

Thomson Financial/First Call

.

And while

Morgan Stanley

may have slashed its investment outlook on

Ciena

(CIEN) - Get Report

to neutral from outperform, citing the communication equipment maker's stock valuation, investors ramped up the stock by 0.4% to $62.65 on Island.

Not all activity could be pegged to news. Youth-oriented retailer

Hot Topic

(HOTT)

wasn't too popular, losing 5.1% to $32.50 on Instinet. The

Smith and Wollensky Restaurant Group

(SWRG)

also made it to Instinet's top 20 volume list, rising 0.4% to $7.80.

And in the most-favored tech camp,

Sun Microsystems

(SUNW) - Get Report

was flat on Instinet, while

Juniper Networks

(JNPR) - Get Report

climbed 0.7% to $53.70. Chip leader

Intel

(INTC) - Get Report

, which has lately been the recipient of favorable analysts' comments, gained 0.4% to $28.90 on Island. Software stalwarts

Oracle

(ORCL) - Get Report

and

Microsoft

(MSFT) - Get Report

were both in negative territory tonight.

Island ECN offers trading mainly in Nasdaq-listed stocks, from 7 a.m. to 8 p.m. EST.
