Basic analysis of the last two growth periods for the S&P 500 gives us an average headroom value before we can expect next pullback. As we are already through the low-end estimate of 4095 experienced during 2018, we look to the average value of 5471, giving us a price target of $3400 on the /ES. This has been a consensus call among many institutional equity traders since the beginning of the most recent trend in Sept/Oct. 2019.
