Null in historical stock price downloads
Many symbols (not all) in Yahoo Finance history data have 'null's. For example AAPl on 8/10/1981 has 'null's. This can observed at below URL. And in Excel CSV file by clicking 'Download Data' on this URL.
I reported this earlier but provide URL that did not work due to required Cookie/Crum.
Hopefully Yahoo Finance will find and correct this problem. Thanks for this excellent service.
