STX risk-adjusted returns: Sharpe, Sortino and volatility

Over 5 years, STX had a Sharpe ratio of 1.11 against 0.67 for the S&P 500, so it earned more return per unit of risk than the index. Its annualized volatility was 55.1% and its beta 2.05: it tended to move about 2.0× as much as the market.

MetricSTXS&P 500
Annual return+66.7%+13.7%

Sharpe ratio1.110.67
Sortino ratio2.921.08
Max drawdown (month-end)−54.8%−23.9%

Sharpe divides return above cash by total volatility; Sortino counts only downside volatility. Both use monthly returns and the 1–3 month T‑bill ETF (BIL) as the risk‑free rate.

How STX behaved in past crashes

STX’s deepest fall in the crises below was −89.1% 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.

The right benchmark for STX

Exent matches every holding to the index with the most similar risk. For STX 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. Read why the S&P 500 is the wrong benchmark for most portfolios.

Data and methodology

Returns are total returns from month‑end adjusted closing prices (dividends reinvested) through Sep 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.

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.
