The late-session mercy shown by investors, who stepped in to buy flagging big-cap techs and other suffering names, continued tonight on Island ECN.

Ciena

(CIEN) - Get Report

sank 7%, or 8 5/8, to 107 7/8 during the day Monday, following Friday's news that the fiber-optics equipment provider expects to see reduced sales of new products and higher costs for parts. Ciena, however, rose 1 15/16 to 109 15/16 on 20,000 Island shares, as traders continued to bargain hunt for slightly cheaper

Nasdaq

"blue chips."

Biopharmaceutical company,

Immunomedics

(IMMU) - Get Report

rallied in anticipation of a

CNBC

interview with company officials at 5:50 EDT. A teaser for the TV chat claimed the company would break positive news in an exclusive interview. In a classic case of buy the rumor and sell the fact, the fervor died down after the announcement.

CEO David Goldberg said that the company had just passed phase two clinical trials for their antibody against non-Hodgkin's lymphoma, a lymph-node cancer. A team from

Cornell Medical Center

will present the results tomorrow. Apparently, the antibody prepared by Immunomedics only takes half an hour to infuse while competitors' drugs take about six hours. The medicine works by targeting the cancer cell, assimilating itself into it and then destroying it. The study showed a 60% response rate in patients who did not respond to other treatments. Lately the drug company's stock was up 1 5/64 to 16 1/64 on 81,000 shares. While post-interview gains were halved, volume doubled after the TV appearance.

Imagine being able to use

eBay

(EBAY) - Get Report

anywhere. Monday, the online auctioneer struck joy in the hearts of shopaholics and rallied 15% on news that eBay will be accessible through

OracleMobile's

mobile portal. Now, more than 12 million registered eBay users will be able to monitor eBay from their wireless devices through OracleMobile, which is available from Web phones, pagers, Palms and other wireless personal digital assistants. Customers will be able to track eBay activity, receive auction alerts and make bids.

Monday evening saw a slight retreat of the day's gains, as traders sobered up from their shopping stupors and sent eBay out to sea, 2 11/16 lower to 133 1/2 on 13,000 Island shares.

After a gory day of tech selling

PMC Sierra

(PMCS)

managed to finish 6% higher at 155 1/2. The semiconductor networking company wasn't so lucky at night, as traders carved into profits and munched away. The Canadian tech company dropped 2 3/4 to 152 3/4 on 13,000 Island shares.

A small-fry stock was sizzling up some volume at the top of Island's most traded list.

Stake Technologies

(STKL) - Get Report

ended the day unchanged at 1 3/8, after trading half a million shares. There was no fresh news to spur tonight's small move, but the Yahoo! message boards posted rumors of a merger and also accusations of a pump and dump. The message board talk should usually be taken with a grain of salt, but occasionally these postings show prescient foresight.

At 2 p.m. EDT,

BroadVision

(BVSN) - Get Report

announced that

Groundswell

, an Internet consulting firm, will use BroadVision's One-To-One solution to assist in building e-business communities for its clients.

Broadvision supplies personalized e-business applications and e-business communities bring together content, products and service providers that revolve around a type of product or industry. BroadVision popped 7/8 to 39 13/16 on 48,000 Island shares.

The word exigent means demanding, difficult and exacting. The aptly named

Exigent International

(XGNT)

was definitely having a tough time of it after it announced Monday morning the award of several new contracts for its software engineering products. It ended the day 3/32 or 4% lower at 2 9/32.

Exigent provides advanced technical solutions for the government and defense industry. These customers did not want to be identified, a press release said. Chairman and CEO B.R. "Bernie" Smedley did reveal that the new customers were in the telephony and wireless market.

After Mr. Smedley's company spent most of the after-hours session in the red, the road turned less exigent toward the end of the session and the stock headed 9/32 higher to 2 9/16 on 86,000 shares.
