Ciena P/E ratioWhat is the P/E ratio? The P/E ratio divides a share's price by its earnings per share over the last year: what you pay for each dollar of profit.
Ciena's P/E ratio is 59.36: its share price of 274.24 over its earnings per share of 4.62 over the last twelve months.

P/E ratio = price ÷ EPS (last 12 months) = 274.24 ÷ 4.62 = 59.36
Each day's closing price over the earnings per share of the last four quarters reported by that day (basic EPS, adjusted for splits). The P/E moves with the price every day and with the earnings at each report.
The forward P/E divides the price by the analysts' average EPS estimate for the next twelve months: the fiscal year in progress for the months left in it, the next one for the rest. For past days it uses each year's latest estimate, as the estimates of the time were not recorded (we keep a daily copy from November 2026), so the past line reads the price against the earnings expected by the time each year was reported.
Is Ciena's P/E high compared with its own history?Is the P/E high or low for this stock? Today's P/E against every daily P/E of the stock's last 5 years, with the growth analysts expect: whether the stock is expensive or cheap compared with itself, and whether its growth explains it.
Ciena's P/E of 59.4 is above the middle of its 5-year range (15.2 to 410.2, median 34.9). Analysts expect faster growth than in recent years, which can explain part of the high P/E.

A P/E is compared with the stock's own last five years, not with other companies. Why the market pays more or less (news, rates, the sector) is not in these figures.
