Tech stocks: BlackBerry sinking, Dell leaps

BlackBerry stock is getting knocked around fresh off the U.S. arrival of the Z10. Let's take a look at the stocks to watch on Monday.

New smartphone can't lift BlackBerry shares. The Canadian electronics maker's stock is down nearly 7% after it launched the BlackBerry Z10 in the U.S. It's available now through AT&T, and will launch this week for T-Mobile and Verizon.

The Z10 marks a significant shift for BlackBerry, as it modernizes its smartphones with apps and touchscreens. Consumers seemed to welcome the Z10 with caution, with some loyal BlackBerry owners opting to cling to older devices with the signature keyboards and trackpads.

Dell buyout talk heats up. Shares of the personal computer maker are up 3% as the company weighs two more buyout bids.

The company confirmed it is looking into bids from investor Carl Icahn and Blackstone Group that could be better than the $24 billion deal proposed by an investor group led by CEO Michael Dell.

Dell says its CEO is working on alternate proposals.
