1. Quadruple Witching Options Expiration - This Friday is options expiration for September. As you know, this is a quarterly expiration which is a quadruple witching options expiration. This means that there are 4 different asset classes expiring under the sun this week. It has been a volatile and choppy trading week so far and I'd expect more of it going forward. 

2. Chinese ADRs (China stocks) are almost impossible to invest in at this time. Today, there is news that the government in China is going to increase gaming industry regulations in the Macau region. Nearly everyday we hear some other new regulation from the Chinese government in a bunch of different industry groups.. It makes the Chinese stock uninvestable at this time. 

3. Bitcoin holding tight right below 50k. Not looking good.

4. Gold/Silver gold is down 11.5. Silver down .10. Nothing to see here.
