From a bitcoin flash crash, to Apple's China cash stash, this is the Week in Numbers....
22% was the plunge in price for bitcoin at one point over the weekend. As ever with cryptocurrencies the reasons weren't totally clear. But some traders say bitcoin was caught up in a general flight from risky assets amid new global health worries.
$82.5 million apparently wasn't paid to bondholders by Evergrande this week, when it should have been. That was enough for ratings agency Fitch to declare a default. Now Beijing says any fallout can be contained, and investors wait to see if that's true.
$275 billion is how much investment Apple reportedly promised China back in 2016 to head off regulatory threats that would have hobbled its business there. That's according to a report in The Information. Apple wouldn't comment, but the investment is thought to have included deals to buy more components in China.
$101 billion is the value that could be put on SUV and sports car maker Porsche. Reuters sources say parent firm VW is mulling what could be a record-breaking IPO. The money raised would help fund the transition to electric vehicles.
And 7.2% was the drop for shares in Chinese social media giant Weibo when they began trading in Hong Kong. The damp debut comes as China's big tech firms come under pressure from regulators at home, and in the U.S. too.
