The Dow Jones Industrial Average ended at the day's high and the Nasdaq Composite Index fluttered up just over the flatline, ending a tumultuous week.

The Dow got the most support from

J.P. Morgan

(JPM) - Get Report

, the banking giant that is merging with

Chase Manhattan Bank

(CMB)

. Morgan, up 7.7%, climbed back in the past week or so from am early September selloff. It was moving higher on general strength in financial stocks today.

Hey, if you're buying, why not pick up a cheap one? Chase also jumped, 6.7% higher. The two financials have been moving in sync with each other since they announced their marriage plans.

The market was being fueled by enthusiasm left over from yesterday's rally, seeing darn good numbers from fiber-optics leader

JDS Uniphase

(JDSU)

and

gross domestic product

figures that indicate a slowing economy.

JDS, which was bullish outlook for coming quarters in its third-quarter

earnings report, gained 3.8%. And while the company's earnings news was good, some analysts are skeptical of the mismatch between the numbers for

Nortel

(NT)

and JDS. (

earlier wrote about

Nortel's earnings, which showed disappointing revenue.) Nortel ended down 6.2% to $42.56.

But the fun in fiber optics was being challenged by negativity in biotech on news that

Amgen

(AMGN) - Get Report

lowered its

sales projections and earnings forecast.

Back in the Dow,

Hewlett-Packard

(HWP)

and

Microsoft

(MSFT) - Get Report

TheStreet Recommends

contributed to the index's upside, with a total of more than 26 points to the positive. Microsoft was the victim of a hack attack on Thursday, which
