For stocks, the month of September has ended just as it started: flat.
The S&P 500 started the month with an utterly flat session, dropping just 0.004 percent. After a slide earlier in the month and a more recent rebound, the index has now logged a whopping September move of … negative 0.12 percent.
To make it even weirder, this follows an identical August drop of 0.12 percent.
But interestingly, September's market has been much more volatile than August's. Among this month's 21 sessions, 12 have seen the S&P rise or fall by more than half of a percent. By comparison, only 5 of August's 23 sessions have seen such a move, according to a CNBC analysis of FactSet data.
To put it another way, the difference between August 2016 and September 2016 is that in the latter, the market took bigger steps on the road to nowhere.
