The 18.5 area for MAGS "seems" like support, but so did the $20 area. I would not overstay the welcome in that one. It may very well go back to $12 before it takes back $23. It may be "finished" until the next "security" scare. If you trade it intraday, it is one thing (it still has enough volatility, but far from what it used to have just a month or two back). If you play it for swings, it is becoming dangerous again, IMTO.
