While you were sleeping

A senior Saudi royal returned home. Prince Ahmed bin Abdulaziz, a younger brother of King Salman, had been living in London, where he criticized the kingdom’s bloody war in Yemen. His return may signal a power shift as the Saudi regime reels from Turkey’s investigation into journalist Jamal Khashoggi’s murder.

General Motors revved its engines… The automaker’s shares surged nearly 10% after it said it sold fewer vehicles but at higher prices, beating analysts’ profit expectations.

…As US stocks ended a volatile week on an up note. The Dow Jones Industrial Average gained 900 points, the S&P rose 2%, and the Nasdaq edged out of correction territory with a 2.5% gain. But October was still a bewitched month, with markets posting their biggest declines since 2011.

Obsession interlude

Matthew De Silva and Corinne Purtill on Bitcoin’s greatest mystery: “Satoshi Nakamoto is one of the wealthiest people on the planet. This person—or persons—has managed to throw global markets into a tizzy, without leaving home (wherever that may be). We know that he—or she—upended the traditional finance system and created a brand-new currency. We just don’t know who he is.” Go down this rabbit hole with the Quartz Obsession email.

Matters of debate

Cape Town prioritizes tourists over locals. Burning commuter trains symbolizes the city’s skewed priorities.

Corporations are past their “peak.” Use of the word on earnings calls hit its own peak last year, and it’s been downhill ever since.

Inequality spells doom for republics. By that yardstick, America’s current decline began in the 1970s (paywall).
