We haven't been in a bear market like this since 2013–2015. To think we will move back into parabolic bull so soon is a bit shortsighted. This chart is more for fun than accuracy, but I could see a prolonged bear / flat market through the rest of 2018. 2019 could turn bull, seeing new ATH around the end of the year, leading to parabolic moves again through the end of 2020.
