The A.I. race is heating up, and according to Christine Short, no one showed that more than Alphabet (GOOGL) last week. She points to the mega cap company's cloud revenue and planned $85 billion capex spending as a clear signal A.I. is here to stay. Ivana Delevska says it will be a long road for Mag 7 companies to deliver on those returns, a risk she says investors should be aware of. She notes Apple's (AAPL) headwinds it needs to address in earnings.
