Stock prices

[JP20201285]

Does anybody have experience of wrong data supplied by MS in Excel? 18th December 2020

For example:

POWERHOUSE ENERGY GROUP PLC (XLON:PHE)

The rise percentage supplied is 18.25% but it is not correct! The correct rise stated on LSE is 16.67%.

BLACKBIRD PLC (XLON:BIRD) shows -2.39% when it should be 0.00% as published on London Stock Exchange.

There are many other examples of wrong data i could write, the prices are always correct but simple percentage calculations are often totally wrong!

It would be helpful If anybody can tell me how I can contact MS to report this?

The only way is to set frowns from within Excel, Microsoft monitors them. In your case an issue is most probably on data provider site, Microsoft actually only gives the interface to the data, but that's no other way. If only you don't know someone from Microsoft who works on this project in person.
