SEC where are you?
No wonder the average retailer is running away from the market and into TBills (despite what the S&P thinks). This whole week has been more about computers running wild than anything, and it needs to be addressed. High frequency trading needs to be reigned in.
Also end double and triple ETFs (both bull and bear ones). The only real purpose they serve is to gamble on.
Finally restore the damn uptick rule already. At least it will force those computers to take some kind of breather.
The SEC has the absolute power to do the above.
While I sure many traders love this kind of volatility, it just keeps the real investors (if they even exist anymore) away.
