Valuation 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.	Gilead Sciences Inc.’s P/E ratio increased from Q4 2019 to Q1 2020 but then decreased significantly from Q1 2020 to Q2 2020.
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.	Gilead Sciences Inc.’s P/OP ratio increased from Q4 2019 to Q1 2020 but then decreased significantly from Q1 2020 to Q2 2020.
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.	Gilead Sciences Inc.’s P/S ratio increased from Q4 2019 to Q1 2020 but then decreased significantly from Q1 2020 to Q2 2020.
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.	Gilead Sciences Inc.’s P/BV ratio increased from Q4 2019 to Q1 2020 and from Q1 2020 to Q2 2020.
