PERFORMANCE HIGHLIGHTS Top contributors to performance: ↑ Security selection was the main driver of relative returns, specifically within the utilities, industrials, and technology sectors. ↑ Overweight positioning to NRG Energy, a North American energy company within utilities, was the top contributor to relative performance due to strong earnings growth. ↑ Overweight positioning to Apollo Global Management, a holding company for an asset manager and a retirement services company, was also beneficial. Top detractors from performance: ↓ Overweight positioning and security selection within communication services was the largest detractor at the sector level, particularly due to underweight positioning of Dish Network. ↓ At the issuer level, underweight exposure to MicroStrategy, a bitcoin development company, was the top relative detractor due to a surge in the price of bitcoin. ↓ Overweight positioning to Dexcom, a leader in diabetes management and technology, detracted following a weak earnings results. | |

Top detractors from performance: ↓ Overweight positioning and security selection within communication services was the largest detractor at the sector level, particularly due to underweight positioning of Dish Network. ↓ At the issuer level, underweight exposure to MicroStrategy, a bitcoin development company, was the top relative detractor due to a surge in the price of bitcoin. ↓ Overweight positioning to Dexcom, a leader in diabetes management and technology, detracted following a weak earnings results. | |
