SAN FRANCISCO -- They're at it again. The mad splitters, darlings of the day traders. Internet companies that will be split in the near future continue to ramp higher ahead of the split.

Many of today's winners are the same as last week's --

DoubleClick

(DCLK)

,

Network Solutions

(NSOL)

and

Exodus Communications

(EXDS)

.

"It's been one of the best trades to make the past few weeks," said one day trader, who asked not to be identified. "With day traders in general, we try to find out what has the best chance to cause a pop in a stock, and if there isn't a lot going on, they'll get a lot of play. Right now, there's not much else going on."

But with the play so well known, the trader said that timing remains the key to making money with a split trade. Typically, the stock will continue to rally after the split date as money comes in from those who weren't willing to pay pre-split prices, but the trader said you have to know when to get out.

"The more this game is played, the more jittery traders become and you might have the split effect taking course earlier and people getting out sooner," he said. "No one wants to be left holding the bag."

DoubleClick, which splits April 2, is up 16 3/4, or 9%, at 196 1/2. It was trading at 104 1/2 on March 11 when it announced the 2-for-1 split. The company also announced a deal with

Comcast

(CMCSA) - Get Report

to provide advertising to companies to which Comcast offers high-speed Internet access.

Exodus, which splits 2-for-1 April 12, was up 13 1/2, or 10%, at 154 1/2. It has almost doubled since trading at 77 15/16 on March 3. Shareholders approved its split last week.

Network Solutions, which splits 2-for-1 March 23, is up 10, or 3.5%, at 298, reaching a high of 307 earlier in the session. In addition to the split, the company announced the launch of a new Website for customers to establish and build an Internet site.
