Tracking VUSB historical volatility helps you see how much Vanguard Ultra-Short Bond ETF's stock price has actually moved over past periods, giving you a baseline to judge whether current option premiums are fair, cheap, or expensive.

Use our scanner to monitor VUSB 30 day historical volatility alongside longer lookback windows and spot the moments when realized and implied diverge.

Historical volatility is the annualized standard deviation of an underlying's past returns, typically measured over rolling windows like 10, 20, 30, or 60 days. The VUSB 30 day historical volatility is one of the most widely watched readings because it balances responsiveness with stability. Comparing Vanguard Ultra-Short Bond ETF's HV to its implied volatility reveals the volatility risk premium — when IV sits well above HV, option sellers tend to have an edge; when HV runs hot relative to IV, buyers may be underpaying for movement.

The fund’s investment objective is to seek to provide current income while maintaining limited price volatility. The fund invests in a diversified portfolio of high-quality and, to a lesser extent, medium-quality fixed income securities. The fund is expected to maintain a dollar-weighted average maturity of 0 to 2 years. Under normal circumstances, the fund will invest at least 80% of its assets in fixed income securities. The fund is designed to give investors low-cost exposure to money market instruments and short-term high-quality bonds, including asset-backed, government, and investment-grade corporate securities.

Although short-term bond funds tend to have a higher yield than money market funds, their share price fluctuates. Because the Ultra-Short Bond ETF will subject investors to principal risk, the fund shouldn’t be viewed as a substitute for a money market fund. Additionally, increases in interest rates can cause the prices of the bonds in the portfolio, and thus the fund’s share price, to decrease.The Ultra-Short Bond ETF is a stand alone product and is separate and distinct from the Vanguard Ultra-Short-Term Bond Fund (VUBFX and VUSFX). Differences in scale, certain investment processes, and underlying holdings are expected to produce different investment returns by the funds.

Sizing a long premium trade, modeling a covered call, or hunting volatility arbitrage all come back to one question: how much has the stock actually moved? Our scanner puts Vanguard Ultra-Short Bond ETF's historical volatility side-by-side with implied readings across every lookback window, so you can see exactly where VUSB HV is running hot, cold, or in line. Make the VUSB 30 day historical volatility — and every other window — work for your edge instead of against it.
