(NYSE: VMW); EMC Corporation (NYSE: EMC); Western Digital Corporation (NYSE: WDC); and Zions Bancorporation (NASDAQ: ZION).  We have given a news summary and the current moves on each.

InterDigital Inc. (NASDAQ: IDCC) was down 3.3% today as is, but now the company is getting slashed and burned on news of what many had considered an obvious coming outcome.  The company ended its strategic review process and it did not find a buyer for its deep patent collection.  Now it is going to proceed on its own licensing or selling patents.  Shares are down over 16% at $37.10 in the after-hours against a 52-week range of $34.61 to $82.50.
NVIDIA Corporation (NASDAQ: NVDA) was down 3% after the Texas Instruments earnings but now shares are down “only” about 0.6% after closing up 2.7% on the day.

Polycom Inc. (NASDAQ: PLCM) has a history of big hits and bad misses, but tonight’s reaction has shares on the up and up.  After beating earnings handily, Polycom shares are up 9.6% at $20.29 and that is after closing up almost 4% today. 

Texas Instruments Inc. (NYSE: TXN) was down initially due to headlines showing GAAP earnings above estimates but the chip giant is now up over 3% ay $34.25 in the after-hours session against a 52-week range of $24.34 to $36.71.

VMware Inc. (NYSE: VMW) closed down 2.4% at $86.00 today but shares are up 5% at $90.50 on almost 1 million shares after just over an hour after the 4PM closing bell.  The virtualization leader said sales rose 27% to $1.06 billion and it sees revenues of $1.015 billion to $1.04 billion for the first quarter of 2012.  These are being taken as above plan.  The news has the (former) parent company of EMC Corporation (NYSE: EMC) up about 1.8% at $23.87 on over 2 million after-hours shares.

Western Digital Corporation (NYSE: WDC) may have seen earnings drop almost 36%, but the update is proving to be above plan and it claims to be making much more progress in Thai floods.  Shares closed up marginally today and the after-hours reaction has shares up 4.4% at $36.25 versus a 52-week range of $22.64 to $41.87.

Zions Bancorporation (NASDAQ: ZION) posted earnings light at $0.30 versus estimates of $0.33.  Its book value per common shares grew to $25.02 from $24.78 one quarter earlier and shares are down 3% at $17.98 in the after-hours.
