Petrovietnam is set to auction its entire 23.21% stake in Petrosetco (HOSE: PET), a leading integrated oil and gas services company, with a starting price of VND 36,500 per share. This move, valuing the entire lot at nearly VND 910 billion, immediately sent PET shares surging to their upper limit on the morning of November 10th, despite the market price still trailing 12% below Petrovietnam's offering price.
