That $189.28 mark is Thursday's closing price. Something is probably up with their data provider, and it is erroneously reporting this value as an after-hours trade. Likewise, BIDU is reporting $87.82 (yesterday's open), AAPL is showing $442 (10 cents from yesterday's open), so the after hours numbers seem to be bouncing around between yesterday's open, and Thursday's close, at least for these few I've looked at.
