PERFORMANCE HIGHLIGHTS Top contributors to performance: ↑ Stock selection was the leading contributor to relative performance across all sectors, most notably in the information technology, industrials and utilities sectors. ↑ Overweight in AppLovin, Vistra and EMCOR Group, all with triple digit returns in the portfolio, were the leading contributors at the security level. Top detractors from performance: ↓ Stock selection detracted from relative returns in the energy sector. ↓ Sector allocation decisions, especially underweight to banks within the financials sector and overweighting non-bank financials. ↓ Overweight in Adobe, Weatherford International and IDEXX Laboratories, all with negative returns for the period, were the leading detractors at the security level. | |
