9/10 times you'll miss the dip and get behind the curve. You have no idea how the market is going to react in the next 6 weeks, much less in the next 6 years.
Trump could have just as easily not implemented the two days of tariffs and the market could have gone up.
Now that the tariffs are off again, the market might bounce back higher than ever on Monday and you're going to miss the bounce.
Of course he might say something incredibly stupid tonight and the market crashes, but again, 9/10 times pulling money out of the market means opportunities lost, not bullets dodged.
You have to be correct TWICE in order to make money off that bet though. Unless you buy back in right now, the chances you'll get back in at the right time are very low.
