>There has been significant recovery in after-hours trading
After hours has been flat. I think what you meant to say is it recovered a tiny bit from it's regular trading hours low. It's still down over 25% on the day.
I know it was recovering in the afternoon, but I didn't think it got to ~85 by the bell. Maybe I misremembered. It doesn't help that SLV is close to, but not equal to the price of 1 oz.
There has been significant recovery in after-hours trading, but check out that "day's range". The low point was around 1:40 PM EST.
