Is it possible to edit yahoo data to fix a bad quote? Yahoo shows a high for QCOM of $438.75 on 9/17/04. If you look at a chart, this is obviously a bad data point because all other data before and after this date re around the $35 dollar range.

We currently do not have a tick editing capability.
I have not tried this, but as a workaround, you can export data from Tools > Historical Data > Export, and export the problem day to a file. Open this file and edit the incorrect value, then import it back in.
Please see this section of the help guide form information on Historica Data import/export.
Keep in mind, if you request from Yahoo the same data over the same period, it will overwrite any changes that you made.
