Today is the triple witching (same-day expiration of stock options, stock index futures, and stock index options contracts). This is usually bearish for stocks and so far it is working pretty good, all stock indices in the US is down and energy metals as well.
Here is on example, the S&P 500 or "Spy" which is down close to 1% right now. (Hourly)
Also, Silver is down big time, just set a 10 month low, here is the weekly chart:
Good time to stack some silver when it is on sale.
Happy trading/investing!
