Assumptions & method
- P/E = Share price ÷ EPS. Earnings yield = EPS ÷ Share price. PEG = P/E ÷ expected annual EPS growth (in percent).
- Trailing P/E uses EPS from the last twelve months (reported). Forward P/E uses estimated EPS for the next period (a forecast). The headline P/E and PEG use the basis you choose.
- If EPS is zero or negative, the P/E, PEG and fair price are shown as "not meaningful". A negative P/E is never displayed. Earnings yield is still shown, with its sign, because it describes the loss relative to price.
- PEG is shown only if growth is greater than zero and the P/E is meaningful.
- Fair price at target P/E = Target P/E × EPS on the chosen basis. It is the price implied by that multiple, not a forecast. The sensitivity table scales the target from 60% to 140%.
- Use per-share EPS on the same share basis as the price (diluted, after splits). One-off items, accounting differences and cyclical earnings can distort the ratio.

What is the price-to-earnings ratio?
The P/E ratio is the quickest way to ask how expensive a stock is relative to what it earns. A high P/E can reflect expected growth or simply a rich price, and a low P/E can signal a bargain or a business in trouble, so the number is a starting point rather than a verdict. Trailing P/E rests on reported profit, while forward P/E leans on analyst estimates that can change. Flipping the ratio gives the earnings yield, which lets you compare a share with other income sources. Adding growth gives the PEG ratio, and the target P/E turns a multiple you believe is reasonable into an implied price you can test against the market.
