Graphs showing errors

Hi - has anyone else noticed that the percentage gain and loss on the graphs are not correct or do not correspond to the correct values as shown on Yahoo finance…

For example BABA is showing a 10% loss today but it’s only dropped $2 from 110 to 108 atm…

Support?

The graphs are indicative and reflect the ask price IIRC. Others use mid/bid/ last traded.

Lol - yeah but if the ask price is $2 lower on a $110 stock the return for a day can’t be -10%…
