2019 vs 2015

The 2013 bubble (top) popped with an 87% correction.
The 2017 bubble (bottom) popped with an 84% correction.

If history repeats, we can expect 2019 to be a long anemic flat period, comparable to 2015.

My best guess is that the 100 and 200 day moving averages will need to go flat for some time before we can see a recovery.
