    Liz Ann Sonders and Collin Martin examine the market backdrop shaped by the Middle East conflict, noting that while oil price volatility has influenced inflation expectations and Treasury yields, its broader economic impact has been limited so far due to lag effects and structural shifts in the U.S. economy. Meanwhile, investor attention has returned to earnings season and AI-driven growth, with a narrow group of mega-cap companies responsible for a disproportionate share of earnings upgrades—highlighting ongoing concentration risks in both markets and fundamentals.

    Then, Collin Martin is joined by Inga Rachwald, director and senior investment portfolio strategist supporting Schwab Asset Management. Inga addresses common challenges, including the perceived breakdown of diversification during periods of market concentration or rising rates, and explains why these are often misinterpretations driven by inappropriate benchmarks. The discussion introduces goal-based investing as a more practical framework, aligning portfolios with specific time horizons and objectives rather than short-term performance comparisons.

    Finally, Collin and Liz Ann look ahead to next week’s upcoming macroeconomic indicators and key data releases.
