We thought that yesterday was a bad day for

TheStreet.com's Internet Sector Index

after 21 out of 25 stocks ended in the red. Today only one DOT component showed any sass, though barely.

RSA Systems

(RSAS)

ended 31 cents higher.

After the bell, the electronic-security firm reported third-quarter financial results that bettered revenue by 29% and beat Wall Street expectations by a penny.

Among the biggest weights on the DOT were search engine

Lycos

(LCOS)

which lost 14%, Internet security firm

Check Point Software

(CHKP) - Get Report

which fell 11% and

Yahoo!

(YHOO)

which lost 13%. After hitting its 52-week-low of $56.62, Yahoo! was beginning to wear that exclamation point ironically.

There were other notable dot-com losers but why rub it in? Okay, you asked for it.

America Online

(AOL)

and

Amazon.com

(AMZN) - Get Report

kicked the DOT while it was down. The tired index ended the day 6% lower at 520.45.

Juniper Networks

(JNPR) - Get Report

turned lower in midafternoon trading, ending the session 3% in the hole after an earlier attempt to buck the broad downturn in tech stocks. The network-equipment maker reports earnings tonight after the bell.

The Nasdaq limped painfully lower today, settling its battered bones 93.81, or 3% lower at 3074.68. It's notable winner today was chipmaker

Intel

, up 5%, benefiting from the misfortunes of primary competitor,

Advanced Micro Devices

(AMD) - Get Report

, after AMD's price targets and EPS outlook were cut by several analysts. (For more on this look below).

The semiconductor sector has been a microcosm of the broader tech market today, battling to post gains amid Mideast unrest and persistent valuation concerns. The battle lately was a failing one.

Initially

KLA-Tencor

(KLAC) - Get Report

lead the way higher after reporting first-quarter earnings of 54 cents a share and beating analyst estimates of 51 cents, as well as its year-ago result of 19 cents. Its earnings, coupled with a positive earnings report late Wednesday from

Advanced Micro Devices

(AMD) - Get Report

, lifted the

Philadelpia Stock Exchange Semiconductor Index

TheStreet Recommends

(SOX)

like a caffeine boost from a morning cup of coffee.

But as unease spread through the markets, the index lost its vigor . The

Philadelphia Stock Exchange Semiconductor Index

, as the index is known, drooped 1.2% to 697.9, after falling to an intra-day low of 692.5 earlier.

KLA-Tencor, a chip equipment maker, was lately off 4.1%.

Despite Advanced Micro Device¿s better-than-expected earnings,

Lehman Brothers

lowered its 12-month price target on the company.

Prudential

followed suit, cutting its price target to $25 from $30 and lowering its fourth-quarter earnings per share estimates and its 2001 EPS outlook. AMD was lately trading 4.3% lower to $22.50.

and

Xilinx

(XLNX) - Get Report

were struggling to lift the semiconductor sector, but they were outnumbered. Xilinx was on the road to recovery after Tuesday¿s

downgrade, which sent waves of panic through the semiconductor sector. It was lately up 6.4%. After being beaten up of late because of slowing growth, Intel was up 5.5%. It will release results on Oct. 17.
