How Will the Stock Market React to June’s Decline?

July 11, 2013

After 7 months of consecutive gains, the S&P 500 Index (“SPX”) dropped by 1.3% in June. While a down month in the market was inevitable, one of the primary worries for investors as we enter the second half of the year is how the stock market will react to June’s losses. In an effort to answer this question, this week’s chart examines market reactions after previous “winning streaks” were broken. For purposes of the analysis, we define “winning streaks” as positive streaks of six months or more for the SPX. From 1954 to 2012 there have been 18 such winning streaks that were broken. Because we are focused on the second half of 2013, we chart the subsequent 6 month returns of the SPX.

Of the 18 data points in the analysis, there were 16 winners (89%) with a median percentage change of 8.87%. In other words, almost 9 out of 10 times, the end of a winning streak has been followed by positive returns in the U.S. stock market. Although historical data may not be indicative of future performance, investors might take comfort from the S&P 500’s past responses to snapped win streaks.
