SanDisk's (SNDK) reported earnings on 19 July 2012

SanDisk's (SNDK, $39.80, +$4.72, +13.45%) second-quarter earnings plummeted as the flash memory maker saw much weaker sales and profit margins, due to soft demand for the company's memory chips from makers of mobile devices. But SanDisk's results were not as bad as some analysts had feared, sending shares sharply higher. Rival Micron Technology Inc. (MU, $5.99, +$0.21, +3.64%) also got a boost from the results.
