Selling was persistent through the session, with the stock holding the low-to-mid $390s in the afternoon before drifting toward $389 with no meaningful recovery attempt.
For shareholders, the key question heading into the next session is whether $390 can act as support. The stock tested that level repeatedly during the afternoon and closed just below it, which makes that price a clear line to watch for any sign of stabilization.
