Barring an event that sends everybody into panic mode it depends on what the fed does which depends on what the economy does. If interest rates stay the same, my SWAG is that the market will stay right where it is now plus or minus the short-term noise.
If interest rates go up I think the market will go down from people taking advantage of higher returns on safer investments.
Um, that was Brexit. Everyone walking on eggshells. Lots of elections coming, so lots of fear, I think.
If the US economy does well, the USD will go up, which will cycle everything down. If the US does badly, $ will fall, so things will pick up.
I love the analogy of the man walking his dog - the dog runs back and forth, but the man keeps walking.
The counter is that, perhaps, Brexit is the beginning of a reversal of global integration. Who knows.
As to predictions, I have no clue. My NW in GBP is up massively since last month. Shame I live in Canada :P
