Here’s a number – 2,000. That’s how many donors we need this fall to stay on track. Can we count on you?
The COVID-19 pandemic has sparked historic stock market volatility in recent weeks, coming on the heels of historic highs.
Maybe you’ve seen the graphs; a steady rise followed by a sharp drop that is now zig-zagging, up and down. That’s what the data looks like. But what might it sound like? Is there a way for us to actually hear how the market has gone from the steady highs of months ago to its current state?
Yes, there is. Thanks to Jordan Wirfs-Brock, an information science Ph.D student at the University of Boulder Colorado. Wirfs-Brock created a 12-second sonification of the stock market from Jan. 2, 2020 to March 27, 2020, where each second represents a week of trading. Using the Dow Jones Industrial Average market data, Wirfs-Brock focused on two metrics: the daily percentage change, to convey volatility and the daily closing price, to convey overall market movement.
Jordan called in from home to give “Marketplace” host Kai Ryssdal a lesson in how to listen. For a more detailed lesson and explanation of the work behind the sonification, check out this Twitter thread
