Closing changes for North American trade on January 10, 2020:

On the day:
- S&P 500 down 9 points to 3265 after hitting 3282 (-0.3%)
- DJIA down 133 points to 28823
- Nasdaq down 24 points to 9178
On the week:
- S&P 500 up 0.9%
- DJIA up 0.7%
- Nasdaq +1.75%
The turnaround today is a bit of warning signal. Note that January is a weak seasonal month but there is a long-term trend of strength early in the month. I also tend to think the signing of the ‘phase one’ deal is sell-the-fact risk.
