Frequently Asked Questions
What is the difference between Trailing P/E and Forward P/E?↓
Trailing P/E uses historical audited earnings from the past four quarters. Forward P/E uses consensus analyst projections for expected earnings over the next 12 months.
Can a company have a negative P/E ratio?↓
When a company incurs a net loss, EPS is negative. Financial platforms standardly report negative P/E as "N/A" because multiple benchmarks lose diagnostic utility when earnings are negative.
What does a high P/E ratio (e.g. 50x or 80x) indicate?↓
A high P/E suggests investors anticipate rapid future earnings expansion, or that current earnings are temporarily depressed by heavy upfront R&D or expansion investments.
What is Earnings Yield?↓
Earnings Yield is the inverse of the P/E ratio (EPS / Price). It allows direct comparison between equity valuations and fixed-income Treasury bond yields.
