IBM Stock Heads for Its Best Week in 25 Years

International Business Machines was on pace for its best weekly performance in 25 years after a federal bet on the company’s quantum technology sent shares into overdrive. The stock has gained more than 17% this week, marking its best performance since April 2001, according to Dow Jones Market Data. The hot streak began after IBM announced the creation of a stand-alone quantum foundry called Anderon, backed by a $1 billion investment from the Commerce Department.
