Morgan Stanley raises Oracle target to $210, sees 32% upside vs Adobe's 10% downside

Morgan Stanley has set contrasting outlooks for Oracle and Adobe ahead of their earnings releases. The bank raised Oracle's price target to $210, implying 32% upside, citing expected cloud revenue growth near the high end of management's 58% to 64% projection, driven by new AI workload capacity. Wall Street estimates Oracle's quarterly revenue will grow approximately 28% to $19.13 billion. Adobe faces different challenges, with Morgan Stanley maintaining an Underweight rating and a $240 target, suggesting 10% downside. Investors are concerned about Adobe's growth strategy under new CEO Anil Chakravarthy, who succeeds Shantanu Narayen on 1 December. Oracle must demonstrate its AI infrastructure investments are driving cloud sales, whilst Adobe needs to reassure markets about maintaining growth through the leadership transition.
