One year ago, Zuckerberg’s net worth was estimated at $74.5 billion, according to Bloomberg’s Billionaire’s Index. As of Tuesday, it had dropped to $55.5 billion – a whopping $19 billion decrease.

Alibaba co-founder Jack Ma, for example, saw his net worth drop to $36.7 billion from $45.6 billion, according to Bloomberg, an $8.9 billion decline.

Amancio Ortega, who founded Inditex fashion group – the parent company of retailer Zara – saw his net worth tumble to $61 billion, from $76 billion.
