It doesn’t mean ANYTHING. Someone is buying some USD. Big deal. If anyone was going to be running around with their hair on fire I think a few days in Oct and Dec would have been it. There’s NOTHING here I can see that is catastrophic or out of the ordinary. The S&P500 futures are down a bit but nothing to signal any kind of a market meltdown. And trust me, Oct-Nov-Dec-Jan I’ve seen plenty of things that would make your hair stand up.
