Marker is a publication from Medium about the intersection of business, economics, and culture. Our editorial team also produces the Buy/Sell/Hold newsletter, and The Mobilist, a blog on the future of batteries, electric cars, and driverless vehicles. As a journalistic publication owned by Medium, Marker maintains editorial independence over the stories it publishes on the Medium platform. Medium’s business interests and investors have no bearing on our work. We avoid conflicts of interest and, where unavoidable, disclose them. Marker employees do not have any financial stake in the companies they cover and may not act on nonpublic information for personal gain or the gain of friends and family. Though we make every effort to be accurate in our reporting, when we are wrong, we acknowledge and correct our mistakes.
