The actions Nasdaq takes, or should take, will be closely watched. Those range from improved testing and backup of its systems to ramping up its crisis management and communicating more clearly with the investing public.
The Nasdaq exchange was born of technology and is dominated by the biggest names in the field like Microsoft, Apple and Google. Thursday's breakdown followed a series of tech-rooted disasters involving various exchanges. They included Facebook's bungled public offering launch on Nasdaq in May 2012, one of the largest IPOs in history. The SEC later fined Nasdaq $10 million for that disruption — the largest penalty it ever imposed on an exchange.
