- August 2026
“Our exploration and production (E&P) holdings (c.19%) give us exposure most directly to rising oil and natural gas prices. We include in this category non-integrated oil sands companies, as this is the GICS approach. The stock here with oil sands exposure is Canadian Natural Resources. The pure E&P stocks have a bias towards the US (EOG, Diamondback and Devon), with one other name (ConocoPhillips) having a mix of US and international production.”

Diamondback Energy Co - New positionClearBridge Investments Appreciation StrategyJune 2026
“Portfolio Highlights The ClearBridge Appreciation Strategy underperformed the benchmark S&P 500 Index in the second quarter of 2026. On an absolute basis, the Strategy had positive contributions from eight of 11 sectors. The IT sector was the main positive contributor, while energy was the main detractor. In relative terms, stock selection and sector allocation detracted. Stock selection in IT, industrials, communication services, financials and consumer discretionary, overweights to materials and energy and an IT underweight detracted the most. Conversely, stock selection in materials and a consumer discretionary underweight were beneficial. On an individual stock basis, the biggest relative contributors during the quarter were ASML, Palo Alto Networks, ASM International, an underweight to Microsoft and not owning Palantir. The biggest detractors were Netflix, underweights to Micron Technology and Advanced Micro Devices, and not owning Intel and Applied Materials. During the quarter, we initiated new positions in SpaceX in communication services, Micron Technology, Cisco Systems, Advanced Micro Devices and Texas Instruments in IT and Diamondback Energy in energy.”
