AVAV vs JOBY: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
AVAV (AeroVironment) and JOBY (Joby Aviation) share investment themes but are different businesses. The right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
AVAV vs JOBY: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | AVAV | JOBY | What it tells you |
|---|---|---|---|
| Market cap | $7.56B | $7.03B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 33.77 | -14.30 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Beta | 1.39 | 2.71 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 5% of range | 4% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 1.71 | 3.58 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Before you buy: how AVAV and JOBY affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. AVAV and JOBY share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined AVAV and JOBY exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does AeroVironment (AVAV) do?
AeroVironment (AVAV) is a defense technology company specializing in unmanned and autonomous systems. It is best known for small, man-portable drones used by militaries for reconnaissance and surveillance, and for loitering munitions, notably the Switchblade family, which are precision-strike drones that have drawn significant attention from conflicts and rising global demand. AeroVironment also builds larger unmanned aircraft systems, uncrewed ground robots, and develops autonomy software and counter-drone solutions. Its primary customer is the US Department of Defense, with growing international and allied-government sales. The company has expanded through acquisitions into adjacent areas such as space, loitering munitions, and autonomy. The investment story centers on the structural growth of drones and autonomous systems in modern warfare, where small, attritable, intelligent systems are reshaping how militaries operate. Founded in 1971 and historically associated with pioneering work in efficient flight, AeroVironment is headquartered in Arlington, Virginia, and is a mid-cap defense growth company tied closely to defense budgets and procurement.
What does Joby Aviation (JOBY) do?
Joby Aviation designs and intends to manufacture and operate electric vertical takeoff and landing (eVTOL) aircraft, small piloted air taxis built to carry a few passengers quietly over congested cities. Its plan is to make money as a vertically integrated transportation-as-a-service business: build its own aircraft (with manufacturing practices borrowed from partner and investor Toyota), then sell rides directly to passengers, distributed through partners like Uber and the Blade passenger business it acquired. Until its own aircraft enters revenue service, nearly all reported revenue comes from that acquired Blade helicopter operation rather than from eVTOL flights.
AVAV vs JOBY: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- AVAV drivers: Loitering munitions demand; Small unmanned systems franchise.
- JOBY drivers: Lead in FAA certification; Strategic backers and balance sheet.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: AeroVironment depends heavily on US defense procurement, so budget cycles, appropriations timing, and program decisions cause lumpy, hard-to-predict revenue and order flow. For JOBY, joby is effectively pre-revenue on its core product: the bulk of its reported revenue comes from the acquired Blade helicopter business, not its own eVTOL aircraft, and it posted a net loss of roughly $110 million in Q1 2026.
AVAV or JOBY: which should you pick?
AVAV vs JOBY: the full fundamentals
AVAV. AeroVironment trades on a growth multiple that reflects its leadership in fast-growing drone and loitering-munition categories rather than current earnings. The valuation embeds expectations of sustained defense procurement growth and successful expansion into autonomy and space. It is more volatile and richly valued than traditional defense primes, sensitive to order timing and conflict-driven demand swings.
JOBY. For a pre-commercial company, the most important figures are cash and burn rather than earnings: roughly $2.5 billion of liquidity against a few hundred million of cash use per half-year implies several years of runway, but no clear path to profitability yet. The reported revenue largely reflects the acquired Blade helicopter operation, not Joby's own air taxis, so traditional valuation multiples are not very meaningful. At a market cap near $9 billion against minimal core revenue, the stock prices in a commercial future that still depends on FAA certification and scale.
Headline figures (approximate, early 2026): AVAV shows revenue (ttm) ~$800 million-$1 billion, operating margin ~low-double-digit percent, net income (ttm) Modest; growth reinvested, p/e (ttm) Elevated (growth multiple); JOBY shows cash & short-term investments ~$2.5 billion (Q1 2026), revenue (q1 2026) ~$24 million (mostly acquired Blade passenger business, not eVTOL), fy2026 revenue guidance ~$105 to $115 million, net loss (q1 2026) ~$110 million.

FAQ
What is the difference between AVAV and JOBY?
+
AeroVironment (AVAV) is a defense technology company specializing in unmanned and autonomous systems. Joby Aviation designs and intends to manufacture and operate electric vertical takeoff and landing (eVTOL) aircraft, small piloted air taxis built to carry a few passengers quietly over congested cities. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is AVAV or JOBY the better stock?
+
Neither is universally better; they suit different views and risk levels. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, AVAV or JOBY?
+
On forward P/E (as of August 2026), AVAV trades at 33.77x and JOBY at -14.30x, so JOBY is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both AVAV and JOBY?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of AVAV vs JOBY?
+
AVAV: AeroVironment depends heavily on US defense procurement, so budget cycles, appropriations timing, and program decisions cause lumpy, hard-to-predict revenue and order flow. It is mid-cap and competes against far larger defense primes as well as a wave of new drone and autonomy startups, which could pressure pricing and share. Demand spikes tied to specific conflicts may not be sustainable, and any easing of geopolitical tension could slow orders. Acquisitions add integration risk and have raised the share count and balance-sheet complexity. The stock is volatile and trades on a growth multiple that embeds optimistic defense-spending and order assumptions, leaving it sensitive to any procurement disappointment. JOBY: Joby is effectively pre-revenue on its core product: the bulk of its reported revenue comes from the acquired Blade helicopter business, not its own eVTOL aircraft, and it posted a net loss of roughly $110 million in Q1 2026. It guided to using $340 to $370 million of cash in the first half of 2026 alone, and reaching profitability is years away and not assured. Certification could slip, raising the chance of further dilutive equity or convertible raises, and the entire thesis depends on an air-taxi market that does not yet exist at scale. The stock is highly speculative and can move sharply on certification, funding, or partnership news.
