Question 1

What is Canadian National Railway's P/E ratio?

Accepted Answer

Canadian National Railway (CNI) P/E ratio is 21.6× as of June 5, 2026. The ratio is calculated by dividing market capitalisation by trailing twelve-month earnings (net income), using USD-normalised financials (IAS 21 exchange-rate translation for non-USD reporters).

Question 2

How is the P/E ratio calculated?

Accepted Answer

P/E = Share Price ÷ Trailing Twelve-Month (TTM) Diluted EPS, or equivalently Market Capitalisation ÷ TTM Net Income. All inputs are sourced from audited GAAP/IFRS filings and translated to USD using period-end exchange rates so the multiple is comparable across companies and currencies.

Question 3

What is the P/E ratio?

Accepted Answer

The price-to-earnings (P/E) ratio, also called the earnings multiple, measures how much investors pay per dollar of a company's trailing twelve-month (TTM) earnings. It is calculated as share price ÷ TTM diluted EPS (equivalent to market capitalisation ÷ TTM net income). A higher P/E implies the market is pricing in stronger future earnings growth or lower risk; a lower P/E can signal slower expected growth, higher risk, or potential undervaluation.

Question 4

What is a good P/E ratio for Canadian National Railway?

Accepted Answer

There is no universal "good" P/E. As a rule of thumb, the S&P 500 has historically averaged a P/E in the mid-to-high teens; mature, slow-growth businesses commonly trade in the 10–18× range, while high-growth or asset-light companies often trade at 25–50×+. What matters is the comparison to sector peers and to the company's own historical range. For Canadian National Railway specifically, the relevant sector benchmark is the current sector median of 27.8×.

Question 5

Is Canadian National Railway's P/E ratio high or low?

Accepted Answer

Canadian National Railway's P/E ratio of 21.6× is above its own 5-year average of 20.0× and below the sector median of 27.8×. That places the current reading at the 75th percentile of its 10-year history. A higher multiple usually reflects stronger expected growth, lower perceived risk, or higher returns on capital; a lower multiple reflects the opposite.

Question 6

What is Canadian National Railway's historical P/E ratio range?

Accepted Answer

In the available daily series, Canadian National Railway (CNI) P/E ratio has ranged from a low of 4.6× in 2009 to a high of 30.7× in 2021. The 5-year average is 20.0× and the 5-year median is 19.5×.

Question 7

What was Canadian National Railway's P/E ratio in 2025?

Accepted Answer

Canadian National Railway (CNI) P/E ratio at the end of 2025 was 18.0×. Annual values reflect the multiple on the last trading day of each calendar year, using the trailing twelve-month earnings figure available at that date.

Question 8

Why does Canadian National Railway's P/E ratio change over time?

Accepted Answer

Valuation multiples move with two inputs: the numerator (market capitalisation, which tracks the share price) and the denominator (earnings). Share-price changes — driven by interest rates, earnings expectations, risk appetite, and broader market sentiment — typically dominate short-term moves, while changes in the underlying fundamental drive the longer-term trend. As a result, the ratio can rise during stock-price rallies even if the business itself has not become more valuable, and fall during sell-offs even when fundamentals are improving.
