Will the S&P 500 level change from increase to decrease, from decrease to increase, from either to zero, or from zero to either, with regard to the 7/5 close level, in the last 2 trading hours on 7/6?

Equivalently, will the S&P 500 level − the 7/5 close level change sign in the last 2 trading hours on 7/6?

Approximately, will the S&P 500 close on 7/6 contrary to traders' prediction on Alex B. Goode's daily S&P 500 question, which closes 2 hours before NYSE close?

This is to complement Alex B. Goode's awesome daily S&P 500 question, in order to form a complete market.
