Array Technologies, Inc. (ARRY) Beta & Volatility
As of May 24, 2026
TL;DR — ARRY beta is 1.79
Array Technologies, Inc. carries a current beta of 1.79 versus the S&P 500, which classifies it as high volatility. Moves materially more than the market. Common for small-caps, recent IPOs, biotech, and concentrated turnaround stories.
That means on a day the index moves 1%, ARRY historically tends to move roughly 1.79% in the same direction — although day-to-day correlation is noisy and only meaningful over rolling windows of several months.
What is beta and how is it calculated?
Beta is the slope of a regression line plotted from a stock's returns against the broader market's returns. We use the S&P 500 as the benchmark and monthly returns over a five-year window — the same methodology that backs the FMP "profile beta" field. A beta of 1.0 means a stock moves perfectly in line with the index. A beta of 2.0 means it has historically moved twice as much in either direction. A beta of 0.5 means it moves half as much. Beta below zero (negative) is rare and means the stock tends to move opposite to the market — gold miners and short-volatility ETFs sometimes show this pattern.

Volatility vs the S&P 500
Holding the S&P 500 has a beta of, by definition, 1.0. ARRY's beta of 1.79 implies its monthly returns are roughly 79% more volatile than the index. In a 10% market drawdown, history suggests ARRY would draw down by roughly 17.9%, all else equal. In a 10% rally it would tend to gain roughly 17.9%. Past performance is not a guarantee — beta is backwards-looking and can shift sharply after major business changes.
Portfolio implications
A high volatility beta like ARRY's changes the role this stock can play in a portfolio:
- Position sizing: if you target a portfolio beta close to 1.0, you can hold a smaller dollar allocation of ARRY and still match the market's overall sensitivity.
- Pairing: pair ARRY with low-beta defensive names (consumer staples, utilities, regulated industries) to dampen overall portfolio swings.
- Discount rate: ARRY's beta directly feeds the cost of equity in any DCF model. A higher beta raises required return and lowers fair value, so a high-beta growth story has to grow fast enough to justify the premium.
- Drawdown tolerance: if a 30% market sell-off would force you to trim, factor in that a high volatility name like ARRY would historically draw down by 54% in that scenario.

Frequently asked about ARRY beta
What is ARRY's beta?↓
ARRY's current beta is 1.79, which puts it in the "High volatility" category. Moves materially more than the market. Common for small-caps, recent IPOs, biotech, and concentrated turnaround stories.
What does beta actually measure?↓
Beta measures how a stock's returns move relative to the broader market (usually the S&P 500). A beta of 1.0 means the stock moves in lock-step with the market. A beta of 1.5 means it tends to move 1.5x as much in either direction. A beta below 1.0 means smaller swings; a beta below 0 means the stock often moves in the opposite direction.
How does ARRY's beta compare to its sector?↓
Energy stocks typically sit around 1.0 (market-like). ARRY's reading of 1.79 is on the higher-volatility end.
How should I use beta in portfolio construction?↓
Use beta to balance the overall risk profile of your portfolio. A high-beta concentrated portfolio amplifies returns in bull markets but can drawdown sharply. Mixing in low-beta names (utilities, staples, regulated industries) dampens swings. Beta also feeds the WACC discount rate in any DCF — a higher beta raises the cost of equity and lowers fair value, all else equal.
Is beta a measure of risk?↓
Beta is a measure of market-relative volatility, not of total risk. It does not capture business risk, accounting risk, regulatory risk, or governance risk. Use beta in combination with the Quality Triple Check (Piotroski / Beneish / Altman) on the fundamentals page to get a fuller risk picture.
