Ratio	Description	The company
P/E ratio	The P/E ratio tells analyst how much an investor in common stock pays per dollar of current earnings.	Biogen Inc.’s P/E ratio increased from 2016 to 2017 but then declined significantly from 2017 to 2018.
P/OP ratio	Because P/E ratio is calculated using net income, the ratio can be sensitive to nonrecurring earnings and capital structure, analysts may use price to operating profit.	Biogen Inc.’s P/OP ratio increased from 2016 to 2017 but then slightly declined from 2017 to 2018 not reaching 2016 level.
P/S ratio	An rationale for the P/S ratio is that sales, as the top line in an income statement, are generally less subject to distortion or manipulation than other fundamentals such as EPS or book value. Sales are also more stable than earnings and never negative.	Biogen Inc.’s P/S ratio increased from 2016 to 2017 but then declined significantly from 2017 to 2018.
P/BV ratio	The P/BV ratio is interpreted as an indicator of market judgment about the relationship between a company’s required rate of return and its actual rate of return.	Biogen Inc.’s P/BV ratio increased from 2016 to 2017 but then slightly declined from 2017 to 2018 not reaching 2016 level.
