Since 2009, the stock market has moved higher on an almost regular basis. Success like this can make it hard to believe that two short years ago the global economy was being buffeted by the Arab Spring uprising and the potential exit of Greece from the European Union. One outcome of these events was a 10% correction in the S&P 500 index. Having moved from that point in time to now without a major pullback, some would say a market setback is long overdue. Last week, there was news that could potentially be the trigger for a correction. Lower than expected company profits and concerns about slowing worldwide growth caused the Dow to lose 3.5%. The NASDAQ, an index that measures technology and growth companies, was down 1.7% for the week.
