Question 1

What is Lightwave Logic's P/FCF ratio?

Accepted Answer

Lightwave Logic (LWLG) P/FCF ratio is currently not available. When trailing twelve-month free cash flow is negative — common during heavy capex cycles or operating losses — P/FCF is reported as N/A and analysts switch to P/S or EV/EBITDA.

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 Lightwave Logic?

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 Lightwave Logic specifically, the relevant sector benchmark is the current sector median of 24.8×.

Question 5

Why does Lightwave Logic'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.

Question 6

Why is Lightwave Logic's P/FCF ratio not available?

Accepted Answer

When trailing twelve-month free cash flow is negative — common during heavy capex cycles or operating losses — P/FCF is reported as N/A and analysts switch to P/S or EV/EBITDA.
