Even billionaires aren’t safe: This year’s market slump has wiped $75 billion from the wealth of Jeff Bezos and Mark Zuckerberg

If last week’s market tumble has you worried about your 401(k) or Roth IRA investments, you’re in good company—even the ultra-wealthy are feeling the pain. Six out of the 10 top richest people in the world have experienced wealth declines between $30 and $60 billion this calendar year, totalling over $255 billion.

Jeff Bezos’s net worth is down $30.7 billion since January, whereas Mark Zuckerberg has faced a decline of $46.3 billion in wealth, according to Bloomberg’s Billionaire Index.
