A joke, yes. We will laugh in the car.
They had to report the news but they didn't have to add that last bit about the rally in September that occured last year. This logic assumes that the stock market follows trends along the calendar. This is shakey logic for timing the market. The investor who follows this advice is probably going to loose money.
While August was widely advertised as the third worst performing month for the S&P 500 over the past 50 years, and has so far lost about 2.4% this month, it may be worth noting that the rally last year did start in August... In fact, the S&P rallied on two separate occasions last year... From Aug. 12 through Sept 21 the S&P surged 6.2%.
