Before a new chip, wireless network, radar system, vehicle component, or piece of electronic equipment reaches a customer, somebody has to prove that it works.

Keysight reports Tuesday after the close, giving you a fresh test of one of technology’s less glamorous but essential businesses.

AI Meets Stability (Sponsored)

One little-known company sits at the intersection of AI, energy, and defensethree of the biggest investment themes in America right now.

Whitney Tilson says it may be one of the safest ways to play the AI boom, and notes that one famous investor reportedly put roughly half his fund into the business.

He’s revealing the company name and ticker free of charge.

Theme: Electronic Testing, Semiconductor Validation, Communications, Aerospace, and Defense Electronics

Complexity Is Good for Testing

The basic investment argument is refreshingly simple.

Electronics keep getting more complicated.

Chips contain more advanced features. Networks operate at higher speeds. Cars contain more sensors and software. Defense systems rely on sophisticated radar, communications, and signal processing.

The harder a product is to design, the more thoroughly it needs to be tested.

You Do Not Need to Pick Every Winner

That gives this theme a useful picks-and-shovels quality.

You do not necessarily need to know which new semiconductor architecture or wireless product becomes dominant.

If companies keep developing more complicated electronics, testing and measurement remain necessary.

What’s Driving It

Keysight Is Tuesday’s Main Catalyst

Keysight releases fiscal Q3 results after Tuesday’s close, with its call at 4:30 p.m. ET.

Its fiscal Q2 was the strongest quarter in company history.

Orders reached $2.051 billion, versus $1.316 billion a year earlier. Revenue climbed to $1.717 billion, and free cash flow reached $472 million.

Communications Solutions revenue rose 35%, including 40% growth in commercial communications and 24% growth in aerospace, defense, and government.

Electronic Industrial Solutions revenue increased 24%, with double-digit growth across automotive and energy, general electronics, and semiconductor markets.

That is unusually broad strength.

Semiconductor Testing Is Surging

Teradyne reported Q2 revenue of $1.329 billion, including $1.122 billion from Semiconductor Test.

The company guided Q3 revenue to between $1.2 billion and $1.3 billion after another strong quarter.

Teradyne tests whether chips work correctly before they reach the devices and systems that depend on them.

More complex processors and memory can increase both the amount and difficulty of testing required.

Defense Electronics Add Another Catalyst

Mercury Systems also reports after Tuesday’s close.

Fiscal Q3 bookings jumped 73.7% to $348 million, pushing backlog to a record $1.6 billion. Revenue increased 11.5% organically to $236 million, while adjusted EBITDA rose 46.2%.

Mercury builds embedded electronics used in radar, communications, electronic warfare, and other defense systems.

That provides a direct look at another market where electronic complexity keeps increasing.

Network Testing Is Improving Too

VIAVI’s fiscal Q4 revenue increased 52.5% to $443.1 million.

Non-GAAP operating margin reached 24.0%, up 960 basis points from the prior year. Management pointed to the data center and aerospace and defense markets as important growth drivers.

Teledyne offers an even broader range of measurement and sensing capabilities. Q2 sales increased 9.8% to $1.663 billion, with record quarterly orders, sales, and operating profit.

Here is the chain reaction:

Electronics become more complex → testing requirements increase
Chip performance rises → validation becomes harder
Networks get faster → measurement equipment must improve
Defense systems add more electronics → demand broadens
Technology spending slows → equipment purchases get delayed

What’s Working

Testing Intensity Is Rising

A more advanced chip is not simply more expensive to manufacture.

It can also require additional testing to make sure the product performs correctly under different workloads, temperatures, speeds, and operating conditions.

That increases the value of the equipment doing the testing.

Demand Is Broad

Keysight’s latest results are particularly useful because strength was not limited to one market.

Commercial communications, aerospace and defense, automotive, energy, general electronics, and semiconductors all contributed to growth.

For you, that makes the theme less dependent on one technology cycle.

Defense Creates Longer Visibility

Commercial electronics can move quickly between boom and slowdown.

Defense programs often operate on much longer timelines.

Mercury’s $1.6 billion backlog and Teledyne’s record orders provide another layer of demand that does not depend entirely on consumer electronics.

What to Watch

Keysight Has a High Bar

After more than $2 billion of Q2 orders, merely decent demand will not be enough.

Keysight previously guided fiscal Q3 revenue to $1.73 billion to $1.75 billion, with non-GAAP EPS of $2.43 to $2.49.

Watch whether orders remain ahead of revenue and whether management raises the full-year outlook again.

Testing Is Still Cyclical

Customers can delay new equipment when semiconductor, telecom, or industrial investment slows.

Testing may be essential, but the timing of the purchase can move.

That makes orders and backlog particularly important.

Acquisitions and Mix Matter

These businesses often span several different end markets.

One strong semiconductor quarter can hide weakness elsewhere.

You want growth that is broad enough to survive when one customer group cools.

Keysight Technologies (KEYS)

What it does: Keysight provides electronic design, simulation, emulation, and testing tools.

Why it fits: Keysight is Tuesday’s main catalyst and the broadest test-and-measurement company in the basket. Q2 orders reached $2.051 billion, while revenue hit $1.717 billion.

What stands out: This is the category leader. Keysight participates across communications, semiconductors, automotive, aerospace, defense, and general electronics.

What to watch: Watch orders, communications growth, semiconductor demand, margins, and fiscal-year guidance.

The Takeaway: Buy this first if you want the broadest exposure to rising electronic complexity. The risk is that exceptionally strong orders make the comparison increasingly difficult.

Teradyne (TER)

What it does: Teradyne builds automated testing equipment for semiconductors and other electronic products.

Why it fits: Teradyne gives you the purest semiconductor-testing exposure. Q2 Semiconductor Test revenue reached $1.122 billion.

What stands out: This is the high-growth chip-testing play. More sophisticated processors and memory can require increasingly demanding validation.

What to watch: Watch semiconductor-test revenue, memory demand, customer concentration, margins, and Q3 execution.

The Takeaway: Buy this if you want the most direct exposure to increasing chip-testing intensity. The risk is semiconductor capital spending eventually cooling.

Under a set of core assumptions, this consumer profile is projected to have a final lifetime portfolio value of approximately $3.24 million if retaining the services of a financial advisor – not accounting for additional savings or portfolio withdrawals – versus a final estimated lifetime portfolio value of $1.56 million without the services of a financial advisor. This example is based on the valuation framework presented in SmartAsset's whitepaper "The Value of a Financial Advisor: What's It Really Worth?" (Nov. 2024). The value of professional financial advice is only an illustrative estimate and varies with each unique client's individual circumstances and portfolio composition. Carefully consider your investment objectives, risk factors, and perform your own due diligence before choosing a financial advisor..

Teledyne Technologies (TDY)

What it does: Teledyne provides digital imaging, instrumentation, sensors, aerospace electronics, and measurement systems.

Why it fits: Teledyne gives you a diversified measurement business. Q2 delivered record quarterly orders, sales, and operating profit, with revenue increasing 9.8%.

What stands out: This is the quality compounder. You get exposure to industrial, aerospace, defense, imaging, and instrumentation rather than relying on one technology cycle.

What to watch: Watch orders, digital imaging, aerospace and defense demand, margins, and cash flow.

The Takeaway: Buy this if you want the steadier, diversified version of the testing theme. The risk is slower growth than the more concentrated names.

VIAVI Solutions (VIAV)

What it does: VIAVI provides network testing, optical measurement, assurance, and communications technology.

Why it fits: VIAVI gives you the network-validation side. Fiscal Q4 revenue jumped 52.5% to $443.1 million, while non-GAAP operating margin reached 24%.

What stands out: This is the operating-leverage play. Higher network speeds and more complex infrastructure require better tools for installing, monitoring, and troubleshooting.

What to watch: Watch data-center demand, network testing, aerospace and defense, margins, and fiscal 2027 guidance.

The Takeaway: Buy this if you want a smaller test-equipment company showing rapid margin improvement. The risk is that recent growth normalizes quickly.

The Takeaway: Buy this if you want testing-adjacent electronic complexity backed by long-duration defense demand. The risk is that contract execution remains uneven even with a large backlog.

Elite Trade Club Insider

A Big Pharma CEO Just Put $1 Million Of His Own Money Into The Stock

You’re looking at one mature healthcare giant where the CEO just made a rare seven-figure open-market purchase and one software company still digesting a massive post-earnings rerating. Elite Trade Club Insider readers are seeing the distinction underneath the filings: one executive voluntarily committed fresh capital, while roughly $1.5 million of software-insider selling was mostly tied to taxes and vested stock.

You’re reading the free version. Here’s what we held back.

Every day, insiders and institutions move millions before the market catches on. We surface the data behind those moves before the rest of the market sees it.

You Read This Far. Here's Where the Real Work Lives.

We run three live portfolios on Autopilot, and everything about them is public: every position, every allocation, every trade, visible the moment it happens.

We keep our own money in each one, because analysis you won't fund yourself is just content.

THE UNBREAKABLE STACK
Our growth book: durable software and cybersecurity names built to compound quietly for years.

THE HORMUZ PREMIUM
Our energy thesis: built for how that sector actually pays, over quarters, not headlines.

THE SQUEEZE
The defensive sleeve: staples and steady compounders, boring on purpose, built for the nights you'd rather sleep than watch futures.

And here's the part that makes it effortless: Autopilot does the trading for you. Connect the brokerage you already use (Robinhood, Schwab, Fidelity, and more) and every move we make gets mirrored in your own account automatically.

Your money never leaves your brokerage. It stays in your account, under your control, and you can override any trade or disconnect anytime. Autopilot even rebalances automatically when allocations drift, and you get a notification every time something happens.

No watching tickers. No timing entries. No fat-finger mistakes at market open. You pick the portfolio, we do the work, your account follows along.

Pick the one that fits your risk level, or run all three:

Live portfolios, real positions, our own capital at stake. Your funds stay in your own brokerage account. Past performance doesn't guarantee future results.

Complexity Is the Opportunity

New technology gets the headlines.

The less visible business is proving that it actually works.

Keysight tests across industries. Teradyne validates chips. Teledyne measures and senses. VIAVI checks communications networks. Mercury supplies the electronics inside complex defense systems.

For you, the theme does not require guessing every future winner.

As long as electronics keep getting harder to design, somebody still has to test them.
