Alpha & Omega Semiconductor Ltd (AOSL) Historical Volatility

Tracking AOSL historical volatility helps you see how much Alpha & Omega Semiconductor Ltd's stock price has actually moved over past periods, giving you a baseline to judge whether current option premiums are fair, cheap, or expensive. While implied volatility tells you what the market expects, Alpha & Omega Semiconductor Ltd's HV tells you what really happened. Use our scanner to monitor AOSL 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 AOSL 30 day historical volatility is one of the most widely watched readings because it balances responsiveness with stability. Comparing Alpha & Omega Semiconductor Ltd'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.

Alpha and Omega Semiconductor Limited designs, develops, and supplies power semiconductor products for computing, consumer electronics, communication, and industrial applications in Hong Kong, China, South Korea, the United States, and internationally. It offers power discrete products, including metal-oxide-semiconductor field-effect transistors (MOSFET), SRFETs, XSFET, electrostatic discharge, protected MOSFETs, high and mid-voltage MOSFETs, and insulated gate bipolar transistors for use in smart phone chargers, battery packs, notebooks, desktop and servers, data centers, base stations, graphics card, game boxes, TVs, AC adapters, power supplies, motor control, power tools, e-vehicles, white goods and industrial motor drives, UPS systems, solar inverters, and industrial welding.

The company also provides power ICs that deliver power, as well as control and regulate the power management variables, such as the flow of current and level of voltage. Its power ICs are used in flat panel displays, TVs, Notebooks, graphic cards, servers, DVD/Blu-Ray players, set-top boxes, and networking equipment. In addition, the company offers aMOS5 MOSFET for quick charger, adapter, PC power, server, industrial power, telecom, and datacenter applications; and Transient Voltage Suppressors for laptops, televisions, and other electronic devices. Further, it provides EZBuck regulators; SOA MOSFET for hot swap applications; RigidCSP for battery management; and Type-C power delivery protection switches. The company was incorporated in 2000 and is headquartered in Sunnyvale, California.

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 Alpha & Omega Semiconductor Ltd's historical volatility side-by-side with implied readings across every lookback window, so you can see exactly where AOSL HV is running hot, cold, or in line. Make the AOSL 30 day historical volatility — and every other window — work for your edge instead of against it.
