You just can't keep 'em down.

In a downright ugly day for technology issues, a handful of highflying third-tier Internet stocks held their ground -- and then some.

After falling with the overall market in the morning,

K-tel

(KTEL)

and

7th Level

(SEVL)

jumped in the afternoon and ended the day up 19% and 30%, respectively, amid heavy volume.

The two companies emerged from relative obscurity recently when they announced new online strategies. Their stocks soared as investors who might have missed out on spikes in

Yahoo!

(YHOO)

or

America Online

(AOL)

raced to get in on what they hope will be the next great Internet success story.

But late last week, both stocks slumped off their highs. They seemed poised to fall further as general market sentiment turned bearish.

"If you asked me if I though those Internet stocks would go up on a day when the Nasdaq was down big, my answer -- after I stopped laughing -- would be 'of course not,'" says

Marc Klee

, portfolio manager of

(NTTFX)

John Hancock Global Technology.

Still, Klee is not shocked at their resilience. Given the stocks' lack of liquidity, the lack of information and hype by both longs and shorts, he says wide price swings are to be expected.

"They're like a guy going into the Mirage casino and betting on black," says

Michael Moe

, the growth-stocks strategist for

NationsBanc Montgomery Securities

. "They defy logical behavior."

They're unlike many aggressive growth stocks that fly up and down on the whims of momentum managers, Klee says, noting that they're more unpredictable because they're retail driven.

Even "traditional" Internet stocks like Yahoo!, down 2.3%, and

Amazon.com

(AMZN) - Get Report

, off 2.5%, held up fairly well today considering their volatility. The tech-saturated

Nasdaq Composite Index

slumped 2.6% with losses coming equally in semiconductors, hardware and every other subsector in the group.

"It's hard to find things that escaped the carnage," says Klee.

Besides the Internet newbies, one other stock that stood out was

Yurie Systems

(YURI)

, a small networking company that received a bid from

Lucent

(LU)

for $1 billion, or $35 per share in cash. The stock jumped more than 10%, or 3 1/4, to 34 3/4 on the news.

Amerindo Investment Advisors

, the company that runs the aggressive

(ATCHX)

Amerindo Technology filed documents with the

Securities and Exchange Commission

that they owned more than 10% of Yurie as of earlier this month. The company could not be reached for comment.
