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%

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.
