The rising stock market of recent weeks has propelled at least eight of the uber-rich into the charmed billionaires’ circle, according to Bloomberg LP.
The data and media company is now tracking billionaires on a daily basis. One week after rival Forbes published its highly regarded billionaires issue, Bloomberg released what it called its a list of eight “hidden billionaires,” who never appeared on any lists — until now.
Bloomberg’s list includes Greenwich insurance mogul William R. Berkley, who has an estimated wealth of $1.2 billion, primarily based on the rising fortunes of WR Berkley Corp., which underwrites property and casualty risks from cyber-security to private aircraft.
Seven other hidden billionaires include Steven Bresky, worth $1.7 billion for his inherited 74 percent stake in Seaboard Corp. of Newton, Mass.; San Antonio-based Graham Weston, worth $1.1 billion derived from his stake in Rackspace Hosting, a provider of Web-based information technology systems; Brazilian father-and-son team Samuel and Michael Klein, worth $2 billion from a public stake in Via Varejo after they sold off their home-appliance stores; Mexican Antonio del Valle, worth $3.2 billion from a stake in Mexichem, a chemical producer; Peruvian Alberto Benavides, whose stake in precious metals producer Cia de Minas Buenaventura is worth $1.2 billion; and Chilean banker Alvaro Saieh, worth more than $2.1 billion.
