New Delhi, December 6: The market debut of oil giant Saudi Aramco has been hogging limelight and also is one of the most sought after Initial Public Offering (IPO). Again, the oil giant came to the news, as the company has priced its share at such a level that it would raise $ 25.6 billion. This sum is expected to make it the world’s biggest IPO. The IPO will establish Aramco as one of the world’s most valuable companies, but the $1.7 trillion figure falls short of the royal family’s anticipated value that comes close to $2 trillion.
