Lackluster volume and Swiss-like neutrality bled from the day into the night. While some Island Interlopers ogled the Fed, others preferred to exchange obscenities, private jokes and endearments on stock message boards. One sweet message simply read, "I love you."

Siebel Systems

(SEBL)

celebrated its new digs with champagne wishes and caviar dreams.

Standard & Poor's

said Monday that the maker of customer service software will replace

CBS

(CBS) - Get Report

in the

S&P 500

. Shares rose 7/16 to 123 5/16 after the announcement, partied up to 134 in Monday's after-hours trading and gained 8% today, hopping 9 61/64 to 130 29/64.

Siebel took its place on the closely watched U.S. market index tonight, and traders welcomed it with a 2 9/16 shot to 133 on 350,000 shares on Instinet.

Pixar

(PIXR)

drew up 1 3/8 to 39 7/16 on 38,000 Island shares after the animation studio announced better-than-expected first quarter net income of $26.3 million, driven by its hit movie

Toy Story 2

. The children's movie grossed $244 million in the U.S. and $479 million internationally, making it the second-highest grossing animated film in the U.S. and the third-highest worldwide. The company is shooting for per-share earnings of $1.25 for fiscal 2000, garnering its confidence from the future release of

Toy Story 3

, which doubtless will feature toy camels smoking cigarettes.

The Northern California-based animation company, which specializes in computer animation, also welcomed Joe Roth, formerly of Pixar collaborator

Disney

(DIS) - Get Report

, and acclaimed animator Brad Bird to its board. Bird, like the artist formerly known as

Prince

, spells his last name with a curious symbol. Bird's looks like a cross between

Sesame Street's

bumbling

Big Bird

and a cross New York pigeon.

P-Com

(PCMS)

just plain plummeted after posting its results. The company manufactures and markets millimeter wave radio systems for the wireless telecommunications market. It says demand is soaring for its products, illustrated by a net sales increase of 50% in the first quarter.

So what if the company disappointed with first-quarter losses of 18 cents a share, while Wall Street pegged its expectations on a 4-cent loss? Can't a company be forgiven if it also reports a 250% increase in product shipments and announces a new $10 million U.S. contract order for its radios?

It was most likely the following quote from President and CEO Jim Sobczak that dampened confidence in the company's position in the fiercely competitive and dynamic telecom racket: "However, while demand was strong, material procurement costs and other start-up costs were a constraining factor during the quarter, and additionally impacted gross margin."

P-Com pooped out and pouted, plowing down 1 3/4 to 9 3/4 on 15,000 Island shares.

Nexell

(NEXL)

continued its daytime ascent after reporting that French researchers used the company's product to create a treatment for x-linked severe combined immunodeficiency, or SCID. Nexell supplies therapeutic and diagnostic products based in stem cell technology and the disease it helped create a treatment for what is commonly called "boy in the bubble disease," after the

John Travolta

movie that inspired a famous

Seinfeld

episode. It is a good thing that they found a treatment for people in bubbles; now the company is busy working on "market in the bubble disease," which some analysts say has afflicted well-known Western bourses.

Nexell's stock gained more than 30% tonight, pushing up 1 15/32 to 4 15/32 on 300,000 Island shares.
