NEW YORK (TheStreet) -- Dell shares rose 2.9% to $14.55 on Monday after news came that the PC maker received additional takeover bids.

A consortium of investors led by Blackstone Group submitted an offer of $14.25 a share for the company that would allow shareholders to receive either a cash payment at that value or continue to own their publicly traded holding. Francisco Partners and Insight Venture Management will participate in the Blackstone investor group.

BlackBerry shares fell 3.76% to $14.35 after Goldman Sachs downgraded the stock following a weak launch of the Z10 smartphone in the U.S.

Analyst Simona Jankowski removed the Waterloo, Ontario-based technology firm from Goldman's Americas Buy List due to a disappointing launch at AT&T ; the overall consensus had moved higher on BlackBerry since Goldman added the company to the Buy List in late November. Since the Nov. 29 add, shares are up 34%, compared with a 10% climb in the S&P 500. Jankowski downgraded the stock to "neutral," and lowered the price target to $17 from $19.

"We now assign a 20% probability of success for BB10, down from 30% previously, as the disappointing launch of the Z10 at AT&T reduces our confidence that sell-through of the BB10 will be successful in the important US market," Jankowski wrote in her report.
