The Dow Jones industrial average wasn't as fortunate, falling 45 points to finish at 10,450.14.
IBM shares rocketed up $6.15 to $106.05 after Salomon Smith Barney analyst John Jones said the company will likely meet earnings estimates in the current fiscal year.
"In the Q&A IBM declined to comment on the current economic environment," Jones wrote in a research note. "However, the fact that it conducted this session and from the way it characterized its 2001 outlook at last month's fourth quarter 2000 EPS (earnings per share) release, one could conclude, and we do, that IBM remains comfortable with 2001 consensus EPS."
