SanDisk (SNDK +4.1%) is an Apple supplier and issued light guidance on its earnings call ... yet shares have rallied to within $2 of their 52-week high. Why? Because the guidance - Q1 revenue of $1.225B-$1.3B ($1.37B consensus) and 2013 revenue of $5.3B-$5.6B ($6.01B consensus) - is accompanied by a forecast for just 30%-40% NAND flash industry bit growth, and lower bit growth from SanDisk. That's fueling hopes of a healthier pricing/margin environment - gross margin fell 300 bps Y/Y in Q4 to 39.9%. Needham has upgraded shares to Buy. MU +0.8%.
