My view is you’ll be damned if you do and damned if you don’t.
Lighten up positions and we’ll see the rally keep going for another year. Stay the current course and see a reversal of form.
I think volatility will certainly return in 2018. How and why is a mute point.
The only thing we can rely on is the system.
If you’re unsure, then hold off allocating more funds until a decent pullback occurs (>5%) but remember we didn’t see one in 2017.
