| Year | ZS | S&P 500 | Difference |

| 2026 (to Oct 30, 2026) | +5.7% | +11.7% | −6.0% |

| 2019 | +18.6% | +31.2% | −12.6% |

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

Over 5 years, ZS had a Sharpe ratio of **0.04** against 0.58 for the S&P 500, so it earned less return per unit of risk than the index. Its annualized volatility was 48.8% and its beta 0.82: it tended to move about 0.8× as much as the market.

| Metric | ZS | S&P 500 |
| --- | --- | --- |
| Annual return | −5.7% | +12.0% |
| Volatility (annualized) | 48.8% | 15.5% |
| Sharpe ratio | 0.04 | 0.58 |
| Sortino ratio | 0.06 | 0.91 |
| Max drawdown (month-end) | −74.0% | −23.9% |
| Beta to the S&P 500 | 0.82 | 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 ZS behaved in past crashes

ZS’s deepest fall in the crises below was **−57.6%** in the 2022 inflation bear market, against −25.4% 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 | ZS | S&P 500 | Loss on $100,000 |
| --- | --- | --- | --- |
| 2018 trade-war selloff | −24.4% | −20.2% | −$24,370 |
| COVID crash (Feb–Mar 2020) | −39.4% | −34.1% | −$39,400 |
| 2022 inflation bear market | −57.6% | −25.4% | −$57,650 |
| 2025 tariff selloff | −19.0% | −19.0% | −$19,030 |

| Window | ZS max drawdown |
| --- | --- |
| Last 1 year | −64.9% |
| Last 3 years | −64.9% |
| Last 5 years | −76.4% |
| Last 10 years | −76.4% |

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

Correlation runs from −1 (moves opposite) to +1 (moves in lockstep). Over the last 60 months of monthly returns, ZS’s correlation with the S&P 500 was **0.26**, with the Nasdaq‑100 0.38, with long Treasuries (TLT) 0.16 and with gold (GLD) −0.14.

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

| Least correlated large caps | Correlation | Most correlated large caps | Correlation |
| --- | --- | --- | --- |
|  | −0.36 |  | 0.66 |
|  | −0.29 |  | 0.64 |
|  | −0.27 |  | 0.60 |
|  | −0.24 |  | 0.59 |
|  | −0.24 |  | 0.53 |

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 ZS’s revenue comes from

In fiscal 2019 (the year to Jul 31, 2019), ZS’s largest reported region was the United States, with 49.1% of its $302.8 million revenue. By region: United States 49.1%; Emea 41.1%; Asia Pacific 7.9%; Other 1.9%.

By business, the largest segment was Reportable Segment, with 100.0% of $3.4 billion revenue (+25.4% on the year before).

From ZS’s annual filings; segment growth compares fiscal 2026 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.

## How much of ZS is sold short?

As of the Sep 30, 2026 settlement date, **5.46%** of ZS’s float was sold short: 5.8 million shares, or 1.8 days of average trading volume to cover. A year earlier (Oct 15, 2025) it was 5.05%. The median across the 997 US stocks Exent tracks was 4.77%, so ZS is more heavily shorted than most.

From FINRA short‑interest reports, filed twice a month; the bars show the short share of the float at each month‑end. Days to cover divides the shares short by the average daily volume. [The most shorted stocks](https://www.exent.ai/resources/most-shorted-stocks)

## Is ZS diluting shareholders?

ZS’s diluted share count **rose 18.1%** over the five fiscal years to fiscal 2026 and rose 3.8% in fiscal 2026 alone. Each share now owns a smaller slice of the company. The median change across the 1,005 US stocks Exent tracks was −0.1%.

- **+3.8%** share count, 1 year

- **+18.1%** share count, 5 years

- **24.5%** stock pay as % of revenue

- **0.00%** buyback yield

## ZS financial health scores

In Exent’s Oct 20, 2026 snapshot, ZS’s Altman Z‑score was **4.46**, in the safe zone (where 465 of the 794 non‑financial US stocks Exent tracks sit). Its Piotroski F‑score was **4 out of 9**; 88% of scored stocks reach 4 or more.

- **4.46** Altman Z‑score: safe zone

- **4/9** 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)

## The right benchmark for ZS

Exent matches every holding to the index with the most similar risk. For ZS 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.
