The companies’ annualized gain over the 15-year period was nearly 18% versus 9% for a broad stock index that tracks shares in 47 countries. The billionaire-controlled companies were also more profitable.
“The outperformance we call the ‘billionaire effect’ depends on the entrepreneur keeping control, irrespective of whether the business is public or private,” the report said.
What makes billionaires special
Billionaire entrepreneurs have an “optimistic attitude,” focusing on risks they understand and reducing them. They also constantly hunt for opportunities and are “undeterred by failures and roadblocks,” it said.
“Billionaires’ enterprises tend to pursue a long-term strategy that benefits from an exceptional alignment between performance and management incentives,” the report added.
It found that close to 27 million jobs could be directly or indirectly linked to billionaire-controlled enterprises.
Billionaire wealth dips in 2018
Following years of growth, the “billionaire boom” experienced a “natural correction” in 2018 on a stronger dollar, market volatility and economic weakness, said Josef Stadler, an executive at UBS Global Wealth Management.
The number of billionaires fell by 57, with especially sharp declines in China and India. Only the Americas bucked the trend, lifted by the fortunes of US tech entrepreneurs. There were 89 US tech billionaires at the end of 2018, up from 70 in 2017.
Billionaires ended 2018 nearly 35% wealthier than five years earlier, owning a combined $8.5 trillion in assets. The number of women billionaires increased 46% over the same time period to reach 233, but that’s only 11% of the total.
Tech is king
The net wealth of tech entrepreneurs has almost doubled over five years to $1.3 trillion, with the number of billionaire-controlled tech companies rising from 76 to 148.
Ten of the world’s top 20 tech billionaires are from the United States and four are from China, including ByteDance founder Zhang Yiming.
Industrial entrepreneurs saw their wealth decline 15% to less than $609 billion against a backdrop of declining commodity prices.
Billionaires looking to grow their wealth are increasingly favoring direct private investments over listed equity markets, said Simon Smiles, an executive at UBS Global Wealth Management.
