Saudi Aramco faces tough test less than a month after $25-billion IPO

Saudi Aramco’s status as an oil-producing behemoth located in one of the world’s most turbulent regions always marked it as likely to suffer bouts of volatility. But few could have expected the stock to face so stern a test less than a month after the company’s historic $25.6 billion initial offering.

The world’s most profitable company extended declines on Monday after dropping to its lowest closing price yet a day earlier.
