Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of data storage specialist Quantum (NYSE: QTM) have sped upward by as much as 14% after a Bloomberg report stoked speculation that the company may be acquired.

So what: The report in question indicated that NetApp (Nasdaq: NTAP) may need to look at acquisitions to compete with rival EMC (NYSE: EMC), and that CommVault Systems (Nasdaq: CVLT) and Quantum would both be attractive candidates. NetApp has seen weakness in Europe amid troubling macroeconomic conditions while EMC holds more market share in the area.

Now what: The ISI Group believes that NetApp should now use its $4.6 billion of cash on the balance sheet for takeovers as organic revenue growth has slowed, and ISI named Quantum as an attractive target while Robert W. Baird & Co. said CommVault would be a good fit. ISI analyst Brian Marshall said picking up Quantum makes sense since NetApp already resells Quantum's offerings. NetApp and EMC had both bid on deduplication specialist Data Domain in 2009 before EMC won out, and buying Quantum would give NetApp exposure to deduplication.
