Calcbench has added ratios to our point-in-time standardized fundamentals stream. Now you can back-test the impact of changes in industry standard measures of profitability, liquidity and solvency. See the list of ratios @ https://www.calcbench.com/home/standardizedmetrics.
Ratios are calculated when filings are received. When one component of the ratio is revised a new ratio value is calculated and published with the timestamp of the component.
Calcbench’s point-in-time data is available from our API or on our bulk data page. For help getting the data contact firstname.lastname@example.org.
