Market leadership broadened, with mid- and small-cap indices performing better than large caps. The Iran conflict influenced market behavior. AI-related investments supported capital spending and earnings, though investor sentiment was mixed. The portfolio saw negative absolute returns but outpaced the Russell 2000® Growth Index, offering some downside protection.
