Question 1

What is Ciena's P/FCF ratio?

Accepted Answer

Ciena (CIEN) P/FCF ratio is 85.8× as of June 5, 2026. The ratio is calculated by dividing market capitalisation by trailing twelve-month free cash flow, using USD-normalised financials (IAS 21 exchange-rate translation for non-USD reporters).

Question 2

How is the P/FCF ratio calculated?

Accepted Answer

P/FCF = Market Capitalisation ÷ Trailing Twelve-Month (TTM) Free Cash Flow, where Free Cash Flow = Operating Cash Flow − Capital Expenditures. 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/FCF ratio?

Accepted Answer

The price-to-free-cash-flow (P/FCF) ratio compares a company's market capitalisation to its trailing twelve-month (TTM) free cash flow. It is calculated as market cap ÷ TTM free cash flow, where free cash flow = operating cash flow − capital expenditures. Because FCF cannot be inflated by non-cash accounting items, P/FCF is often considered a cleaner measure of "earnings-power valuation" than P/E — especially for capital-intensive businesses where depreciation diverges from real cash outflows.

Question 4

What is a good P/FCF ratio for Ciena?

Accepted Answer

Mature companies that consistently convert profit into cash often trade at 15–25× P/FCF; capital-intensive businesses with lumpy capex typically trade lower. Compare against sector peers and against the company's own multi-year average — single-year P/FCF can be distorted by working-capital swings. For Ciena specifically, the relevant sector benchmark is the current sector median of 21.6×.

Question 5

Is Ciena's P/FCF ratio high or low?

Accepted Answer

Ciena's P/FCF ratio of 85.8× is above its own 5-year average of 56.9× and above the sector median of 21.6×. That places the current reading at the 83th 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 Ciena's historical P/FCF ratio range?

Accepted Answer

In the available daily series, Ciena (CIEN) P/FCF ratio has ranged from a low of 7.7× in 2009 to a high of 2788.2× in 2013. The 5-year average is 56.9× and the 5-year median is 26.7×.

Question 7

What was Ciena's P/FCF ratio in 2025?

Accepted Answer

Ciena (CIEN) P/FCF ratio at the end of 2025 was 40.4×. Annual values reflect the multiple on the last trading day of each calendar year, using the trailing twelve-month free cash flow figure available at that date.

Question 8

Why does Ciena's P/FCF ratio change over time?

Accepted Answer

Valuation multiples move with two inputs: the numerator (market capitalisation, which tracks the share price) and the denominator (free cash flow). 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.
