Interesting...Just witnessed something unusual, something reported here before. I watched us close at $18.90 up 54¢ with a bid of $18.89 and an ask of $18.99. Then at 4:10 a trade went through which sent the closing price to $18.99 up 63¢.
Is this legal? My understanding is that shares can continue to trade until 4:30pm at the closing price only. I'm not really complaining as we closed 9¢ higher, but had it been the other way around and we closed lower, it'd bother me alot more.
Or is it possible that there was a market order at the close that for some reason hadn't been executed yet, which would cause the price to rise as there were no more shares at the lower ask?
As I said, interesting...
