Are happy ETF days back?

A few months ago when ETFs like SKF or SRS would make $ 20, 30 or 40 dollar runs or FAZ making a 30% intraday run was like being in trading nirvana. I always try to keep focused on what a stock is doing at the moment and not dwell on could happen or profit targets. Why limit myself?. Instead I open myself to the reminder that these things move like nothing else. The old adage that it's never to high to buy or low to short sell is still true. You never know where they can end up.

 Today I feel some similiarities in the force behind the moves compared to a few months ago. Have the happy hunting times returned? Will events set the wheels in motion for a market crash or rocket lauch? Time will tell. Would I hold these overnight? Never in a million years.
