I'm not worried at all: in fact, I've been yammering about this year becoming a repeat of 2014. If I'm right, then 2019 will be a huge buying opportunity: an ideal time to dollar cost average.
To prepare for the possibility, I'm putting my ambitions on hold and focusing on paying down as much of my debt as I can. Exiting 2018 debt-free will put me in a position to take advantage of 2019.
Oh, I love the link about your dollar cost average and the point behind it. Very good to point out.
Yes, especially if 2018 is a cruel bear and 2019 is a go-nowhere year.
I'm still kicking myself for not dollar-cost averaging throughout 2015 and most of 2016.
