Amazon.com, Inc. (NASDAQ: AMZN) managed to blow past earnings and guide revenues higher.  All this while margins continue to be overlooked.  Shares were up and are up even more now at all-time highs… The gain is up 6.7% at $228.65 on nearly 3 million shares since the 4PM bell.

Avalon Rare Metals Inc. (AMEX: AVL) is getting squashed after a filing for the sale of 7 million shares of common stock “to complete a bankable feasibility study on the Thor Lake Project and for working capital and general corporate purposes.”  Shares rose 6.9^ today to $6.81 and shares are almost giving it all back with a 6% drop to $6.81 in the after-hours.

Illumina, Inc. (NASDAQ: ILMN) fell 3.6% today to $69.65 ahead of earnings.  It beat estimates but gave light guidance for 2011 after having seen such a big run before.  Shares are down over 9% at $63.25 right before the closing bell.

Internet HOLDRs (NYSE: HHH) has traded an unusual 13,000 shares and is up 3.3% at $81.98 in the after-hours session.  The reason is simple: the weighting is over 48.5% Amazon.com.

Networking equipment makers be damned!  Juniper Networks, Inc. (NYSE: JNPR) is down over 13% at $27.04 on more than 3.4 million after-hours shares.  The “little-Cisco” turned in light earnings for the second quarter and guidance for the third quarter looked light as well after blaming deployment timing delays of service provider.

Speaking of Cisco Systems, Inc. (NASDAQ: CSCO), if things are soft at Juniper the idea is that there is no way things are great before the company has even implemented a turnaround and restructuring yet.  Cisco is down 1.7% at $16.01 on nearly 1 million shares since the 4PM bell.  Elsewhere, CIENA Corporation (NASDAQ: CIEN) is down 5% at $16.70 after the closing bell.

Linear Technology Corporation (NASDAQ: LLTC) may have grown revenues 27% but the focus and emphasis is on light guidance for the next quarter.  Shares are down right at 5% at $29.65 in the after-hours session this evening.

Questcor Pharmaceuticals, Inc. (NASDAQ: QCOR) managed to turn in above-estimate earnings sales after the close, sending shares up 8.8% at $28.30.  Keep in mind that the 52-week range before this was $9.01 to $28.20.

Tempur Pedic International Inc. (NYSE: TPX) was halted, a fear, but the fear was unwarranted… The company beat earnings, raised guidance, and started a share buyback plan.  Shares closed down 1% today but the after-hours session has shares up 6.4% at $66.02.
