Arm Holdings has become the UK’s sixth most valuable company after the Cambridge-based chip designer saw its shares close almost 50% higher by the end of the day’s trading session in New York.
The Nasdaq-listed firm now has a market cap of $117 billion -- overtaking the likes of FTSE stalwarts Diageo, GSK and BP and within reach of surpassing the value of consumer giant Unilever, which has a market cap of $129 billion.
