Trade Hopes dashed – It turned out a deal with China wasn’t quite yet a done deal. Politicians should be reminded that markets move much faster than trade negotiations or Congress.
Yield Curve approaching inversion – Five-year drops below two-year, but maybe we should wait for the ten year to drop too.
Rising Interest rates – based on Fed fund futures, the chance that the Fed raises interest rates on December 19th is 80%
Brexit – British Prime Minister May lost a round in Parliament while the European Union might let Britain withdraw its Article 50 request to leave – if the British were to change their minds.
The US Economy – GDP growth is good, unemployment is low but home sales are slowing and business capital spending looks soft. Will the stock market spoil consumers’ optimism?
VIX above 20 – just about normal. Since the end of 2000, the average is 19.5
While anything, and everything, on this list could explain why the market dropped over 3% today, the main reason was probably that it started to sink and everyone followed along.
