Bullish Gator

What stands out

Joe Mazzola, speaking in Charles Schwab's Mid-Year Market Outlook, says AI optimism has returned but the rally is narrow, led by chip and AI memory names while market breadth thins and volatility picks up. He warns that stronger Gross Domestic Product (GDP) and Personal Consumption Expenditures (PCE) readings could be the catalyst for broader participation beyond the handful of winners. For investors that means watching earnings from chipmakers and AI supply-chain names, and paying attention to breadth and volatility rather than price headlines alone.
