Oracle chief executive Larry Ellison topped the list of those recording billions of dollars in paper losses, according to the CEO Wealth Meter, compiled by CNET Investor. The Oracle chief lost more than $6 billion from his total holdings in the software giant, according to a tally.
Microsoft chief executive Steve Ballmer ranked high on the list, with paper losses of nearly $1.2 billion in his company's stock.
Dell CEO Michael Dell had losses of more than $1.4 billion, according to the Wealth Meter.
Among the dot-com billionaires, Amazon.com CEO Jeff Bezos lost more than $130 million. America Online's Steve Case lost close to $37 million.
But the high-tech big shots still have plenty of money; Ellison, for example, still has a net worth of more than $41 billion. That's greater than the gross national product of many countries. Ballmer's net worth stands at nearly $18 billion. And Bezos remains comfortable in his status as a dot-com billionaire.
Not everyone was a loser. One example: PSINet chief executive William Schrader, who gained more than $14 million in paper profits on a rise in PSINet's shares. His total holdings now stand at more than $265 million.
