Hewlett-Packard's taken a wild ride over the past few hours.
Wednesday afternoon the stock spiked after hours on a report that the board was considering a breakup of the company among other options to maximize shareholder value. Hewlett-Packard officially had no comment on the report, but a source close to the company told me HP plans at this point to keep all of the company's businesses together.
No doubt, a couple of things have fueled the latest round of HP speculation—one, the news yesterday that Michael Dell plans to take his company private at $13.65 per share, in a transaction worth about $24.4 billion.

The thing that brought Dell to this point? That's the second thing — the decline of the PC market. It shrank eight percent in the third quarter and another five percent or so in the fourth quarter, as tablets and smartphones have led people to delay PC purchases. That inevitably hurts HP, still the largest PC maker, because it doesn't have and significant presence in the mobile market.
That's why HP is now trading at a $32.7 billion dollar market cap, even though it pulled in $120 billion in revenue in fiscal 2012. The stock is down more than 40 percent over the past year as CEO Meg Whitman has struggled to articulate a turnaround plan that she says won't really begin to bear obvious fruit until 2014.
Some key questions going forward: Can HP roll out a viable mobile strategy at this point? Will the printing business continue to deteriorate along with the traditional PC market? And can HP restructure its enterprise services and product offerings to get better than mediocre margins?
If not, we can expect this breakup chatter to continue quarter after quarter until something gives.
