• P/E ratio (158.8) — how many dollars you pay for each $1 of CIEN's yearly profit. That's high, so the market expects strong growth (and you're paying up for it).
• ROE (15.46%) — how efficiently the company turns shareholders' money into profit. This is a middling level.
• Profit margin (7.87%) — of every $1 in sales, this is what's left as profit after all costs.
• Dividend — CIEN doesn't pay a meaningful dividend; the return here comes from the share price, not cash payouts.
