One of the late session's regulars reclaimed the top volume spot on Instinet Friday, forcing

Enron

(ENE)

, the leading after-hours mover for the past two days, to settle for second.

Oracle

(ORCL) - Get Report

was the volume leader, trading down 1.5% to $13.82. On the Island ECN, shares of the enterprise software maker were fractionally lower.

Enron's rapid and mammoth decline still shows no sign of stopping. After the close, the company gave up another 3.8% to 25 cents. The energy merchant, which this week saw its debt downgraded to junk status and a bailout by

Dynegy

(DYN)

fall through, opened regular trading at 36 cents. Rumors were building that the company is now planning to file for Chapter 11 bankruptcy protection on Monday.

Volume in extra trading was fairly convincing. In the first 30 minutes of action, around 2.9 million shares changed hands among the 20 most actively traded stocks on the Instinet platform.

Centillium Communications

(CTLM)

was one of the biggest losers, dropping 8.5% to $9.20.

Scholastic

(SCHL) - Get Report

was also lower, falling 11.2% to $38.60.

Silicon Image

(SIMG)

was among the biggest winners, trading up 5.5% to $4.45.

The

Nasdaq 100 Tracking Stock

(QQQ) - Get Report

was inching up 0.2% to $39.71 on Instinet.

WorldCom

(WCOM)

was ahead by 0.1% to $14.55, and

Sun Micro

(SUNW) - Get Report

was losing 0.1% to $14.23.

Cisco

(CSCO) - Get Report

was off 0.5% at $20.34, and

Dell

(DELL) - Get Report

was shedding 0.3% to $27.86.

On Island,

JDS Uniphase

(JDSU)

was, as usual, one of the most active issues, trading up 0.4% to $10.12.
