As of this morning, the apocalyptic installations at Dismaland include my stock portfolio. Spurred by China’s market woes, the Dow sank by nearly 1,100 points before bungie-cording panicked investors back towards the black. Is the recent market turmoil a blip or the beginning of the dreaded down-cycle? I’m not sure, but if the market drops much more, we might have to add actual sharing to the sharing economy. In the meantime, don’t sell.

+ For some explanation, here’s The Economist with the causes and consequences of China’s market crash, The New Yorker’s James Surowiecki on the method in the the market’s madness, and China’s stock market crash explained in charts. (Or if you’d prefer, here’s the market panic explained in one chart.)

+ And from The Verge: You know the market is in trouble when Tim Cook is emailing Jim Cramer. (At its lowest point, the Nasdaq plunge briefly triggered mandatory yacht sharing in Silicon Valley.)
