"Tesla's Upgrade Boosts US Equities, Opening Higher"

US equities open higher, with the S&P 500 up 0.5% and the Nasdaq up 0.6%. Tesla leads the gains, surging 5.5% after Morgan Stanley raised its price target and recommended an "overweight" holding. The upgrade was driven by Tesla's development of a supercomputer called DoJo, which will accelerate the adoption of self-driving technology and potentially add $500 billion to Tesla's enterprise value. Meanwhile, NVDA shares are down 1.9%.
