On CAPS, 93% of the 2,099 members who have rated SanDisk believe the stock will outperform the S&P 500 going forward. These bulls include jeffgnewman and MagicDiligence.

Just last month, jeffgnewman succinctly summed up the SanDisk bull case: "Far too cheap, growth in tablets, growth in new markets, price stabilization for flash memory."

In fact, SanDisk sports a cheapish forward P/E of 8.4. That represents a discount to competitors like Micron (10.6), Sony (12.9), and STEC (10.5).

CAPS member MagicDiligence elaborates on the bargain opportunity:

The two big growth markets in consumer electronics are smartphones and tablets. Both are built on flash memory. A major trend in PCs is toward ultra-thin designs, like Apple's (AAPL) Macbook Air. Those designs depend on flash memory (not hard drives) for storage. SSD flash drives are an important part of data center design due to their speed and low power requirements. SanDisk is the purest play in flash memory. Revenues are growing at near 20% annual rates, and margins have improved sustainably due to a shift into product-embedded flash rather than consumer SD cards. So why is this cyclical stock selling at historically low price-to-sales multiples? It doesn't add up.
