SAN FRANCISCO -- The Internet sector continues to have a strong subsector: stocks that are splitting.

Writing in his weekly report on Internet stocks,

BancBoston Robertson Stephens

analyst Keith Benjamin said the recent gains in the sector are the result of the "irrational impact of daytraders" and cautions against chasing the stocks, even if the overall fundamentals of the companies are sound.

"We believe it might make sense to divide our universe into two groups, daytraded and non-daytraded, focusing on smaller news items as catalysts for the former and strategic positioning for the latter," he writes.

Stocks that are splitting in the near future are trading firmer today.

Network Solutions

(NSOL)

was trading up 9 3/16, or 3%, at 293 5/8;

DoubleClick

(DCLK)

climbed 23 3/8, or 15%, to 181;

CMGI

(CMGI)

increased 2 3/4, or 1.5%, to 187 9/16; and

Exodous Communications

(EXDS)

jumped 15 1/8, or 12%, to 141 1/4.

Many of the stocks experiencing these gains today were up significantly for most of Thursday before selling off

late in the session.

Benjamin also had some positive words about Network Solutions, saying that final guidelines from the

Internet Corporation for Assigned Names and Numbers

"appear to allow NSOL to continue growing dramatically with minimal competition."

"We do not believe any company will easily be able to approach NSOL's marketing muscle, which is based on many exclusive deals," Benjamin wrote. "As the last set of news is announced over the next weeks, we believe investors will feel more confident in NSOL's leadership position."
