This is absolutely insane:
At 7:04 AM ET today, President Trump said “the US and Iran have had productive discussions" to end the Iran War.
By 7:10 AM ET, the S&P 500 surged +240 points adding +$2 TRILLION in market cap.
27 minutes later, Iran completely denied all of President Trump's claims and said there has been "no contact" with the US.
By 8:00 AM ET. the S&P 500 had fallen -120 points erasing -$1 trillion in market cap.
That's a $3 TRILLION swing market cap in 56 minutes, just in the S&P 500.
