Hewlett-Packard chief executive Meg Whitman is the technology sector’s wealthiest woman with a $1.3 billion fortune, according to new rankings by Wealth-X.

Facebook chief operating officer Sheryl Sandberg ranked second with a net worth of $1.22 billion, followed by 42-year old Alibaba co-founder Lucy Peng whose wealth stands at $1.2 billion.

HTC chairwoman Cher Wang, came in fourth with $890 million and Marissa Mayer, CEO of Yahoo, ranked fifth with $410 million under her belt.

Stock holdings from their respective companies make up the bulk of fortunes for most women on the list.

For 58-year old Whitman, it was the profits from the sale of her eBay shares back in 2007, Wealth-X notes. Whitman was CEO at the e-commerce firm from 1998 until 2008.

Meanwhile, Sandberg has been selling Facebook shares since 2012, generating more than $700 million in cash before taxes. She still holds around $430 million in Facebook stock, Wealth-X estimates. Facebook currently trades at $83.52 per share.
