Hey woolloomooloo,?

Yahoo Finance shows the opening price was $90.25. Perhaps they had the same issue as you (seeing the two numbers of 9.21 and 9.28) and just took an average of the two lol.
?

Pulling up BIDU's opening price data on 2/5/25, I show the following price action (note that I'm on MST so the market opens at 7:30 for me):
?
?
The above data is sorted Z-A and the bottom-most 4 rows have a code of T indicating those trades were made during non-regular trading hours.?Hovering over and clicking on the code's link takes me to this site here:
?
I imagine the the API's opening price of $90.28 is based on the 4th row (whose value is $90.28 and is the final row having a code of T) or perhaps it's the 5th row's data (whose value is $90.29^8, whatever that means).
?
A few rows further up, we find your $90.21 for the ISLAND exchange with a code of Q, which I believe is the number that you saw a month ago.?
?
All that to say, the two numbers are valid for different reasons. Hopefully that helps clear up the mystery that you were staring down. I for one hate to endure mysteries when my money is involved.?
