Huang falls three places on the Bloomberg Billionaires Index, to eleventh place. This is because Nvidia's share price has fallen 3.2 percent this year.
Since the end of January alone, Huang's fortune has decreased by eight billion dollars - just over 71 billion kronor - but he can take comfort in having 151 billion dollars left.
Siblings Jim, Rob and Alice Walton take the eighth, ninth and tenth spots. They are now worth between $154 billion and $158 billion each after Walmart's stock, by contrast, rose 18.7 percent this year.
This is the first time all three are on the list at the same time.
Entrepreneur Elon Musk still tops the list, with $677 billion.
