Amazon.com did a good impersonation of Cisco's late-1990s 'penny above' routine after the close on Tuesday.

Pro forma earnings of 11 cents a share topped estimates by a penny, and revenues of $1.13 billion topped $1.12 billion forecasts. Fourth quarter revenue guidance of $1.76-1.91 billion compared favorably to $1.78 billion forecasts, and Amazon issued $5.75-6.25 billion revenue guidance for 2004, compared to $6.12 billion estimates.

Amazon slipped after hours, as traders were looking for more upside.

Also after the close, RF Micro, Avaya, Internet Security, CheckFree, Seagate, Cymer, eCollege.com and Advanced Fibre beat estimates. StorageTek missed revenue estimates, and webMethods and AsiaInfo warned.

Stocks were mixed during the day. Techs got a boost from Texas Instruments' blow-out quarter and guidance, while the Dow traded lower on AT&T's and SBC's disappointing results.

The Nasdaq rose 15 to 1940, the S&P 500 added 1 to 1046, and the Dow fell 30 to 9747. Volume rose to 1.45 billion shares on the NYSE, and 1.74 billion on the Nasdaq. Advancers led 18-14 on the NYSE, and 18-13 on the Nasdaq. Upside volume was 53% on the NYSE, and 71% on the Nasdaq. New highs-new lows were 232-7 on the NYSE, and 239-6 on the Nasdaq.

J2 Global plunged 24% on a warning.

JDA Software, Earthlink and Silicon Labs surged on their results, while FindWhat, Ameritrade and Altera edged higher on their reports.

Chinese Internet stocks were hit on earnings worries. Sina, Sohu and Netease lost 7-11%.

IXOS surged 18% on a buyout.

Click2learn and Docent surged on merger plans.

And George Soros continues to prop up Bluefly.
