Computer Problems at London Stock Exchange

The London Stock Exchange suffered disruptions for the last 40 minutes of the trading day due to a computer problem which resulted in incorrect share prices being displayed. The trading day was extended for another 90 minutes to make up for the problems traders were having.

The last major disruption at the LSE occurred in the first week of April 2000. That week also saw computer problems hit the Nasdaq and Toronto Stock Exchange as well. That week reaffirmed the old maxim that bad news comes in three.

Is it time for a repeat?
