BOCI has released a research report expecting all three leaders in China's oil sector to report a YoY reduction in their earnings for 1Q25, with SINOPEC CORP (00386.HK) +0.020 (+0.471%) Short selling $101.16M; Ratio 15.918% suffering from the largest decline, after considering that the average price of Brent crude slipped by 8% YoY during the same period.As the recent drop in oil prices was caused by a nosedive in net long of managed funds in oil futures, BOCI believes that oil prices have already bottomed out. In addition, given that the H-shares of the three major Chinese oils currently offer an expected dividend yield of 7.5-8.3% for 2025 at current price levels, the broker considers them sufficiently attractive.Related NewsM Stanley's Latest Focus List for H Shrs, CN ADRs, A Shrs (Table)BOCI kept an Outperform rating on the oil sector, and it preferred CNOOC (00883.HK) +0.120 (+0.671%) Short selling $38.50M; Ratio 2.872% and PETROCHINA (00857.HK) +0.060 (+0.919%) Short selling $94.57M; Ratio 9.599% more.(HK stocks quote is delayed for at least 15 mins.Short Selling Data as at 2025-05-27 16:25.)
