S&P 500 Index - 12-month closing high in August suggests a September pullback

S&P 500 Index - 12-month closing high in August suggests a September pullback. We note that if the S&P 500 Index were to finish August above 1,960.2 (currently 2,000 points) that would mark a 12-month closing high. Interestingly, whenever the S&P 500 finished August at a 12-month closing high, September was unkind to US equity investors. Since 1950, following this particular market pattern, the S&P 500 lost on average -1.15% over the next month with only 2 September gains from 16 observations. Perhaps, the band - Earth, Wind & Fire, were a little off target when they suggested in their song 'September' - never a cloudy day. Full data analysis & tables can be viewed at (VIEW LINK)
