Apple may be looking to purchase ARM Holdings in an attempt to take chip design in house, according to the London Evening Standard.
Investors seemed to think an approach was more likely for ARM, the Cambridge-based technology company which was recently promoted to the top flight. The chipmaker's shares shot up 8.1p to 251.1p, topping the Footsie winners' list, as more than five million shares changed hands by midday.
A deal would make a lot of sense for Apple, said one trader. That way, they could stop ARM's technology from ending up in everyone else's computers and gadgets.
It's thought that a bid by Apple would come in at around 400p a share, valuing ARM at more than £5.2 billion or $8 billion US.
Apple currently has about $41.7 billion in cash reserves.
