$KUNLUN ENERGY (00135.HK)$ $PETROCHINA (00857.HK)$ $SINOPEC CORP (00386.HK)$ The neighbor $CNOOC (00883.HK)$ Yesterday's close was 8.57, today's open is 9.45, it has already surged. Lately, the focus should be on cyclical sectors, most of which are undervalued, with strong earnings visibility and inflation hedging qualities, matching the recent global market trend. Oil and gas commodities are currently in an uptrend, with major banks predicting a rise to 100 dollars this year. I cautiously expect it to approach previous highs, but the average oil price and demand in 2022 should exceed that of 2021; refer to my earlier article for analysis. Additionally, investment in oil and gas exploration and development has been contracting since the low oil prices of 2015. The negative oil prices in 2020, coupled with the energy transition towards carbon neutrality, have pushed it further into a trough. There is now insufficient developable resources, and the period from discovery to production for oil fields typically spans 10 years (2015 + 10), which will manifest in the end market. If we don't invest soon, there really will be a shortage of oil and gas, and the shift to renewable energy won't happen fast enough. Oil and gas remain crucial as raw materials for chemical products, so let’s do the right thing.
