1. Pound crashes: Investors in Britain woke up to discover the pound suffered a mysterious flash crash during the wee hours of the night, plunging 6% to $1.18.
The currency quickly recovered most of its losses to trade around $1.23. The jury is still out on what triggered the brief episode, but computer trading algorithms likely played a role.
The pound was already under pressure because of worries that Britain is heading for a "hard" exit from the European Union. The currency is now down more than 16% since the U.K. voted in June to leave the bloc.
2. Airline stocks grounded: The pound's decline immediately registered in the shares of U.K. companies that need to deal in stronger foreign currencies.
Low cost airline easyJet ( and IAG, the parent company of British Airways, were particularly hard hit because the weaker pound pushes up the cost of buying jet fuel, which is priced in dollars. )
IAG shares dropped 2% in early trading, while easyJet shed 3%. The discount airline estimated earlier this week that its currency losses would total 180 million pounds ($230 million) over two years.
3. U.S. jobs report: America just got one of its last checkups before the presidential election.
The Labor Department said Friday morning that the U.S. economy added 156,000 jobs in September and the unemployment rate ticked up to 5%.
Economists surveyed by CNNMoney had forecast 175,000.
