On June 15, US AI chip stocks rallied sharply, with the Philadelphia Semiconductor Index breaking above 14,000 points to a record high. Micron Technology closed up over 10%, approaching $1,080, after TD Cowen hiked its price target from $660 to $1,500. Western Digital surged over 16%, AMD rose over 6%, and Nvidia gained over 3%. Three factors drove the rally: the US-Iran peace deal boosted risk appetite, multiple investment banks sharply raised memory chip targets, and Nvidia's bond offering was oversubscribed three times — signaling strong AI capex.
