The Brown Advisory Large-Cap Growth Strategy experienced a decline in the first quarter of 2026, modestly trailing the Russell 1000 Growth Index. Despite negative absolute returns amidst volatility, relative performance improved significantly as the quarter progressed. Initial pressures stemmed from weaknesses in the software sector, affected by concerns over AI disrupting traditional models. Conversely, sectors like Industrials and Consumer Discretionary positively contributed to performance, while Information Technology and Health Care were the largest detractors. The strategy’s ability to outperform in a down market indicates the quality of holdings.
