ⓘ What are these valuation metrics?▾
P/E = share price ÷ earnings per share (EPS)
P/B = share price ÷ book value per share (BPS)
P/S = share price ÷ sales per share
P/E shows how many times annual earnings per share the price is; not all earnings are paid to shareholders. P/B compares the price with net assets, and P/S with sales.
Higher or lower is not good or bad by itself. Typical levels differ by industry; read P/B alongside ROE and P/S alongside margins.
ChickenStock computes these from SEC financial filings: net income and revenue are summed over the latest four quarters, and equity is the latest reported balance.
A negative P/E means a net loss. Reference information only, not a recommendation to buy or sell.
