After months of gains, strategists were expecting a correction, meaning a major decline (5%-10%) followed by another leg to the rally. Sure enough, it happened, with all three major indices approaching 5 percent declines. The trigger, however, was not the usual market.
As one pundit put it... it is always the unexpected, and in this case it was the Middle East and Japan.
