200 dma is ~1877 if we dip below that..?
By all accounts the S&P’s 200-Day Simple MA is around 1905 and it went almost exactly straight to it almost exactly at the close. After the 4 PM close it bounced and then dropped below 1900. So the 1877 isn’t the right number but as of “unofficial” after-market trading the S&P is in fact below it.
