By more vigorous attention to detail.
It must be know to your team that a large percentage of Yahoo Finance data has been systemically incorrect forever. Have you no interest in revamping the system to get data that is current and correct? It is a great format and highly useful for investors, but, unfortunately, one cannot rely on the data. Things like: 'number of shares in the float being larger than the number of shares outstanding' show that the site is not properly monitored. If the site were cleaned up and you announced "The New and improved Yahoo Finance", I would be glad to take a premium subscription as would hordes of others. Getting data from so many different sources has led to contradictory information. Maybe you are already working on improving it. If so we investors would like to hear about it. How about monthly press releases to delineate your progress? And, please do not revamp the format; it is fine the way it is and millions are used to it. Just correct the data collection and create an algorithm to alert you of obvious and possible inaccuracies.
