Other theories point to the unsettling economic climate in Europe and political turmoil in Greece. According to the New York Times, whatever caused the sell-off “set off algorithmic trading strategies, which in turn rippled across everything.” The incident highlighted the role that technology—allowing high-frequency trades in nanoseconds—plays in the business markets.
