Ege Kaan – Wall Street and U.S. Macro Strategy Lead: "The earnings surge underscores the S&P 500’s underlying resilience, yet rising volatility and interest‑rate risks set the stage for near‑term corrections. Portfolio managers should exercise measured aggression in high‑growth sectors like Technology and Healthcare, balancing risk‑reward dynamics to preserve upside potential."
