Where people go is valuable information.

When a private jet carrying representatives from the oil company Occidental landed in Omaha, Nebraska in April 2019, to interview Warren Buffett, news of the arrival extended beyond the chairman and CEO of Berkshire Hathaway. Alternative data company Quandl, which tracks private jet flights, shared news of the visit to its hedge fund clients, who reportedly pay upwards of $100,000 a year for the information. The cost paid off days later, when Buffett announced a $10 billion investment in Occidental, sending its value skyward.
