David Ballin says strong corporate earnings and early signs of AI profitability are helping push U.S. markets to record highs despite macro headwinds. He argues the recent pullback in software has been overdone, creating opportunities in names like CrowdStrike (CRWD) and Palo Alto Networks (PANW). Ballin also stresses the need for diversification, pointing to healthcare, international markets, and select defense and hybrid tech plays like Axon (AXON) as investors navigate high rates and accelerating AI investment.
