How the US stock market is a cryptography problem that almost no one

Allison Bishop

Proof Trading

Abstract:
On any given day, billions of shares are traded on the US stock market. Nonetheless, institutions who seek to buy or sell large amounts of stock may stick out in the crowd and fall victim to predatory behavior. They refer to this problem as "information leakage," which sounds technical, but there is no widely accepted definition of the phenomenon, and little in the way of public-facing research on the topic. In this talk, I'll describe why cryptographers and computer scientists are well-suited to approach this problem, and why more public research would be good for the health of the financial industry. I will also discuss the related historical and economic trends that have influenced the structure of the US stock market, leading to its current state.
