NEW YORK (

TheStreet

) --

IBM's

(IBM) - Get Report

popular CEO Sam Palmisano will step down at year-end, the tech bellwether

announced

on Tuesday. Palmisano will be replaced by the company's sales chief, Virginia Rometty, the first female CEO in IBM's 100-year history.

In a statement, IBM explained that Palmisano will remain chairman of the board, adding that the CEO transition will take place on Jan. 1.

IBM CEO Sam Palmisano will step down next year.

"Ginni Rometty has successfully led several of IBM's most important businesses over the past decade -- from the formation of IBM Global Business Services to the build-out of our Growth Markets Unit," said Palmisano, in the statement. "But she is more than a superb operational executive -- with every leadership role, she has strengthened our ability to integrate IBM's capabilities for our clients."

Palmisano, who took IBM's reins in 2002,

successfully guided

the tech giant through the economic downturn, and helped architect its push towards

high-margin areas

such as software and services.

Like Palmisano, Rometty is also an IBM veteran,

having joined the company

as a systems engineer in 1981.

IBM also announced plans to

beef up its share buyback

on Tuesday.

Big Blue's stock closed UP $1.57, or 0.84%, at $187.45 on Friday.

HP

(HPQ) - Get Report

will keep its PC division, the company's CEO Meg Whitman

announced

on Thursday, after spending the last few months

considering a spinoff

of its computer business.

The possible PC spinoff, one of a host of strategic changes announced by the company's former CEO Leo Apotheker earlier this year, proved massively unpopular with investors. Ultimately, the strategy contributed to

Apotheker's ouster

last month.

"HP objectively evaluated the strategic, financial and operational impact of spinning off PSG. It's clear after our analysis that keeping PSG within HP is right for customers and partners, right for shareholders, and right for employees," explained HP CEO Meg Whitman, in a statement released after market close.

Whitman's move won plaudits on Wall Street, although analysts have warned that she still has

lots of work to do

before HP gets back on track.

HP's shares ended the week up 95 cents, or 3.52%, at $27.95.
