Value of Fundamentals don't match values in MorningStar

When I write my first notebook to test data retrieval, I found the data is different from MorningStar.
Could anyone tell me the reason?

One main reason for the discrepancy is all Morningstar data on Quantopian is quarterly. The Morningstar page shows annual numbers. Therefore, those numbers will be approximately four times bigger (also note that the Morningstar page is in percent so multiply by .01).

As an example, the calculation for ROE is Net Income / Average Total Common Equity. On the Quantopian site the numbers are quarterly so the net income would be the net income for the quarter. (
