"Alternative data" is Wall Street's name for information that
comes from non-traditional sources: satellite photos of parking
lots, credit card panels, weather forecasts. Eric Mannes has
spent over a decade at Jane Street, first as a commodities trader
and now helping lead the firm's alternative data team. In this
episode, Eric and Ron talk about what it takes to turn messy
external data into datasets a trading strategy can rely on. Along
the way, they cover the day oil futures settled at a negative
price and the systems that broke as a result; the years when the
commodities desk's risk system was one very large Excel
spreadsheet; the hard question of what a company even is; and why
better ML models raise the value of careful data engineering.
