[ATL is "all-time low."]
If that is wrong by a fraction, three minutes after the close today, another 12,200 shares traded even lower, giving a final price on the day of 50.5 cents. With that, the change on the day came to -8.18 percent. Almost everything else mining-related had a bad day too.
The market is looking for the Fed to announce tomorrow that it will cause upward pressure on interest rates. The knee-jerk anticipation of this almost always hurts miners. On the flip side, if the Fed makes no changes, miners should recover quickly (at least for a while).
