Brexit = A "no-deal" situation exists, with a series of continuing deadlines to see what the UK actually wants to do. (See https://zurl.co/1PBQ for more info).

Federal Reserve raising rates = They're most likely done for now, with some concerns over an economic slowdown (possibly globally = See https://lnkd.in/gZgnUPK for more info).

US-China trade war = While rhetoric has died down, it's unclear how much will actually get accomplished in the end.

What is clear from the above is that these events clearly show an impact on & concern over the global economy slowing within the next couple of years. For now, the "risk on" mentality is still favorable, although it's not clear now much longer that will last. Stay tuned.
