Historically, tumultuous times offer some of the best opportunities to buy stocks, and the market's recent mess surely qualifies. Many tech stocks have taken a big hit in the last few years, including memory maker SanDisk (NASDAQ:SNDK), but many investors see many compelling reasons to consider buying shares of the company today.

In our Motley Fool CAPS community, 1,721 investors have given a bullish or bearish opinion on SanDisk. Poring through the detailed information packed in pitches and other comments, I've dug up three of the top reasons why many members consider the stock a buy today.

1. Anticipating growth: The Semiconductor Industry Association recently reported sequentially improving chip sales for the second quarter, and its president forecast a better-than-expected outlook for PCs and cell-phone sales. Taiwan Semiconductor Manufacturing (NYSE:TSM) recently echoed this sentiment, which investors see as a big plus for SanDisk and chip makers like Texas Instruments (NYSE:TXN), Qualcomm (NASDAQ:QCOM), and Intel (NASDAQ:INTC). SanDisk's chief even put his own reputation on the line, saying he believes that the worst of the downturn is over and issuing a cautiously optimistic outlook for the second half of 2009.

2. Back to profit: After four consecutive quarterly losses, SanDisk swung to a surprise second-quarter profit, helped by increased pricing and higher royalty revenue. It reported stronger gross margins than in the first quarter and generated higher sequential product sales and license revenue, which validated the bullish logic held by the many CAPS members who are fans of the company's strong intellectual property.

3. Tech comeback: In addition to SanDisk's improving financials, others around the tech industry, such as storage companies Western Digital (NYSE:WDC) and Seagate Technology (NASDAQ:STX), pulled in healthy quarters. Reports from the two hard-drive makers and other bellwethers in the sector, like Intel, gave new evidence that people are buying gadgets and computers again.

Of course, there's a lot more devil in the details of these buy-side opinions, which is why CAPS is such a great resource to check and balance your own analysis. You can read the bullish and bearish sides to every stock.
