Though we have come to expect extreme volatility as the norm with technology and Internet sectors, it's still a little surprising to see the

Nasdaq

do what it has done so far today.

After tumbling more than 140 points early on, the Nasdaq erased most all of those losses, lately up 2.43, or 0.05%, to 4612.43. What happened was fairly simple. Traders, spooked by what went on yesterday, sold into the opening, sending the Nasdaq toward its March 16 low of 4455.10. But other traders were just waiting for that area to be tested, buying just ahead of the low, allowing the market to recover.

Internet stocks followed a similar course.

index traded as low as 1142.22, just above its low of 1135.31 from that same March 16 date. It recently was up 20.35, or 1.72%, to 1205.18. Ever the bull, our own

It's worth revisiting a number of stocks that were pummeled by this weekend's

Barron's

story on the burn rate of Internet stocks.

Pegasus Research

, which did the study for

Barron's

, changed the burn rate for

Healtheon/WebMD

(HLTH)

, but the stock had only recouped a small portion of yesterday's 4-point slide, not nearly all of it. Healtheon WebMD was up 13/16, or 2.8%, to 30 5/16 in recent trading.

A couple of other companies publicly disputed the findings, but their results were mixed today. Many of the problems developed because the data used in the study were based on fourth-quarter revenues and expenses, and did not include any additional investments or offerings the companies might have had since the beginning of the year.

ShopNow.com

(SPNW)

, which said it had sufficient cash to support operations through 2001 rather than the 6.45 months that the article stated, was down 1 3/4, or 9.6%, to 16 1/2 after losing 12% yesterday. The company had a follow-up offering last month.

Also,

CDnow

(CDNW)

, which was No. 2 on the

Barron's

list, also disputed the story, pointing out that it had $40 million in cash on hand, in part due to investments by

Time Warner

(TWX)

and

Sony

(SNE) - Get Report

. It was off 11/16, or 12%, to 4 15/16 today after tumbling 17% yesterday.

Also,

PurchasePro.com

(PPRO)

, whose CEO, Charles Johnson Jr., said the report was "completely erroneous" when he appeared on

CNBC

Monday, was down 6 1/4, or 4.8%, to 123. The company had a stock offering last month that raised $151 million, leaving it with a burn rate of more than three years, according to

Credit Suisse First Boston

, instead of the 10.25 month burn rate listed in

Barron's

. It declined by 15% yesterday.

A number of other stocks were still reeling.

Secure Computing

(SCUR)

, which dropped 14% Monday, was down another 1 3/16, or 6%, to 18 9/16.

Infonautics

(INFO) - Get Report

, which dropped 13% Monday, was down 13/16, or 7.9%, to 9 1/2.

Pilot Network Services

(PILT)

, which fell 14% Monday, was down 4 5/16, or 10%, to 38 9/16 recently.

Peapod

(PPOD)

was flat at 3 1/8 today after declining 12% Monday.

With the market going nuts this morning, we missed a couple of items of note, including some action by analysts that moved a few stocks.

W.R. Hambrecht

reiterated a strong buy rating on

Copper Mountain Networks

(CMTN)

and a 100 price target following news that

3Com

(COMS)

was expanding its

relationship with the company. Copper Mountain was lately up 1 19/64, or 1.5%, to 89 31/64.

W.R. Hambrecht also initiated coverage of

Breakaway Solutions

(BWAY) - Get Report

with a strong buy and a 150 price target, and

Cambridge Technology Partners

(CATP)

with a neutral rating and a 20 price target. W.R. Hambrecht has not done underwriting for either company. Breakaway was up 1 1/2, or 1.3%, to 113 1/2, though it traded as high as 118 1/4. Cambridge was down 3/16 to 14 3/8.

Also,

U.S. Bancorp Piper Jaffray

initiated coverage of

AskJeeves

(ASKJ)

with a strong buy rating and a 12-month price target of 193. It was up 6 1/8, or 9.9%, to 68.
