Facebook stock closed at $203.23 July 6 — an all time high — which propelled CEO Mark Zuckerberg beyond Warren Buffet to become the world's third richest person, according to Fortune and the Bloomberg Billionaires Index.
Over the past 12 months, Facebook's stock has risen 28 percent compared to a 12 percent gain by the S&P 500.
Facebook stock dipped earlier this year after it was revealed that it enabled Cambridge Analytica to improperly access the personal information of up to 87 million users, though the company's value quickly recovered.
