## CIEN risk-adjusted returns: Sharpe, Sortino and volatility

Over 5 years, CIEN had a Sharpe ratio of **0.86** against 0.58 for the S&P 500, so it earned more return per unit of risk than the index. Its annualized volatility was 52.4% and its beta 1.32: it tended to move about 1.3× as much as the market.

| Metric | CIEN | S&P 500 |
| --- | --- | --- |
| Annual return | +42.7% | +12.0% |
| Volatility (annualized) | 52.4% | 15.5% |
| Sharpe ratio | 0.86 | 0.58 |
| Sortino ratio | 1.73 | 0.91 |
| Max drawdown (month-end) | −47.5% | −23.9% |
| Beta to the S&P 500 | 1.32 | 1.00 |

[Sharpe](https://www.exent.ai/learn/sharpe-ratio) divides return above cash by total volatility; [Sortino](https://www.exent.ai/learn/sortino-ratio) counts only downside volatility. Both use monthly returns and the 1–3 month T‑bill ETF (BIL) as the risk‑free rate.

## How CIEN behaved in past crashes

CIEN’s deepest fall in the crises below was **−89.5%** in the global financial crisis (2007–09), against −56.5% for the S&P 500. The last column turns that into money: what a $100,000 position would have lost from peak to trough.

| Crisis | CIEN | S&P 500 | Loss on $100,000 |
| --- | --- | --- | --- |
| Global financial crisis (2007–09) | −89.5% | −56.5% | −$89,550 |
| 2018 trade-war selloff | −11.8% | −20.2% | −$11,780 |
| COVID crash (Feb–Mar 2020) | −22.4% | −34.1% | −$22,420 |
| 2022 inflation bear market | −49.4% | −25.4% | −$49,390 |
| 2025 tariff selloff | −38.5% | −19.0% | −$38,540 |

| Window | CIEN max drawdown |
| --- | --- |
| Last 1 year | −63.2% |
| Last 3 years | −63.2% |
| Last 5 years | −63.2% |
| Last 10 years | −49.5% |

## What moves with CIEN, and what doesn’t

Correlation runs from −1 (moves opposite) to +1 (moves in lockstep). Over the last 60 months of monthly returns, CIEN’s correlation with the S&P 500 was **0.39**, with the Nasdaq‑100 0.42, with long Treasuries (TLT) 0.20 and with gold (GLD) 0.22.

Adding a 5% CIEN position to an S&P 500 portfolio would have moved its 5‑year volatility from 15.5% to 15.9%.

| Least correlated large caps | Correlation | Most correlated large caps | Correlation |
| --- | --- | --- | --- |
|  | −0.17 |  | 0.56 |
|  | −0.15 |  | 0.50 |
|  | −0.13 |  | 0.49 |
|  | −0.11 |  | 0.48 |
|  | −0.11 |  | 0.46 |

Holdings that are highly correlated behave like one position in a selloff. See [how to find hidden overlap](https://www.exent.ai/resources/is-my-portfolio-diversified).

## Where CIEN’s revenue comes from

In fiscal 2024 (the year to Nov 2, 2024), CIEN’s largest reported region was North America, with 73.5% of its $4.0 billion revenue. By region: North America 73.5%; Emea 16.2%; Asia Pacific 10.3%.

By business, the largest segment was Networking Platforms Segment, with 75.8% of $4.0 billion revenue (−12.9% on the year before).

| Segment | Revenue | Share | Growth |
| --- | --- | --- | --- |
| Networking Platforms Segment | $3.0 billion | 75.8% | −12.9% |
| Global Services | $537.2 million | 13.4% | +3.3% |
| Platform Software and Services Segment | $358.1 million | 8.9% | +17.8% |
| Blue Planet Automation Software and Services Segment | $77.6 million | 1.9% | +12.2% |

From CIEN’s annual filings; segment growth compares fiscal 2024 with the year before. Regions are as each company reports them, so one company’s “Asia Pacific” is not another’s. China counts the regions a company reports as China, Greater China or Hong Kong; a separately reported Taiwan is not counted.

## CIEN financial health scores

- **7.14** Altman Z‑score: safe zone

- **8/9** Piotroski F‑score

The Altman Z‑score combines five balance‑sheet and earnings ratios into one bankruptcy‑risk score: below 1.81 is the distress zone, 1.81–2.99 grey, above 2.99 safe. It is not meaningful for banks, insurers and REITs. The Piotroski F‑score counts nine yes/no tests of profitability, leverage and efficiency; 8–9 is strong, 0–2 weak. Both come from the latest annual statements. [Which stocks have the highest bankruptcy risk?](https://www.exent.ai/resources/altman-z-score-bankruptcy-risk-stocks)

## How much is CIEN’s CEO paid?

Gary B. Smith, CIEN’s President and CEO, received total pay of **$18.5 million** for fiscal 2025, up 31.6% from $14.1 million for fiscal 2024, according to the company’s [proxy statement](https://www.sec.gov/Archives/edgar/data/936395/000119312526047977/0001193125-26-047977-index.htm) filed with the SEC on Feb 12, 2026. 79% of it came as stock and option awards, valued when they were granted rather than when they pay out. The median CEO pay across the 378 S&P 500 companies Exent tracks was $17.2 million.

| Pay component | Amount | Share of total |
| --- | --- | --- |
| Salary | $1.1 million | 5.8% |
| Stock and option awards | $14.6 million | 79.0% |
| Incentive plan (cash) | $2.8 million | 15.1% |
| Other | $12,858 | 0.1% |

| Other top executives | Role | Total pay, 2025 |
| --- | --- | --- |
| Marc D. Graff | SVP and CFO | $13.0 million |
| Jason M. Phipps | SVP, Global Customer Engagement | $5.2 million |
| David M. Rothenstein | SVP, Chief Strategy Officer and Secretary | $4.2 million |
| Dino DiPerna | SVP, Global R&D | $3.8 million |

Figures from the summary compensation table of the proxy statement; awards count at their grant‑date value, so one large multi‑year grant can make a single year stand out. [CEO pay across the S&P 500](https://www.exent.ai/resources/ceo-pay-sp-500)

## The right benchmark for CIEN

Exent matches every holding to the index with the most similar risk. For CIEN that is **QQQ** (the Nasdaq‑100). Comparing a holding with an index that carries very different risk makes good results look bad and risky ones look clever.

## Data and methodology

Returns are total returns from month‑end adjusted closing prices (dividends reinvested) through Oct 30, 2026. Crisis drawdowns and trailing maximum drawdowns use daily prices. Analyst coverage counts ratings published in the last 12 months, shown with a 30‑day delay. Full method: [Exent methodology](https://www.exent.ai/methodology).

Company data as of Oct 20, 2026. The move around an earnings report runs from the close before it to the close after it; a price target counts as hit when the stock closed at or beyond it within 12 months (Exent analyst data). Revenue by region and segment, share counts and executive pay come from company filings; insider trades from SEC Form 4, short interest from FINRA, institutional ownership from 13F filings, Congress trades from STOCK Act disclosures filed with the House and Senate, federal contracts from USAspending.gov. Filings from the last 30 days are shown as counts only.
