How has Semiconductor Equipment & Materials moved against S&P 500?

The line below covers up to 5.2 years and opens on the 5Y view; the buttons cut it shorter. Over the most recent two of them this industry is 143% ahead of S&P 500. Earnings across its companies fell 11% on average over the last four reported quarters.

Semiconductor Equipment & Materials, equal-weighted, based at 200 S&P 500, same base, same start trailing 12-month earnings per share rising falling

Both lines start at 200 in the same week, so the distance between them is the whole story: the industry line is an equal-weighted index of its 27 companies. The bars underneath are trailing 12-month earnings per share, one bar per reported quarter, each member rebased to 100 at the start and the industry taking the median — so a price line pulling away from flat bars is a re-rating, not earnings. A bar turns red when that figure is lower than the quarter before. Rules are fixed and applied identically everywhere on this site: ahead by 5% or more over three months, or behind by 20% or more over a year while earnings grew 20% or more. Hover any point to read both values and the gap. This is a description of what the numbers did, not advice.

02 · sector relative strength, before individual stocks

The central tension: the companies with the most scale are not necessarily the companies creating the most change.

Start with scale. Then earnings trajectory. Then business quality. Only after those three agree should price leadership carry much weight.

4-Factor Sector Score

An additive sector-relative research score. The four displayed point contributions always equal the total: Growth & earnings (35), Capital efficiency (25), Valuation (20), and Relative strength (20). Missing or stale evidence is absorbed inside the affected factor, never applied as a hidden adjustment.

Growth & earnings · 35%Capital efficiency · 25%Valuation · 20%Relative strength · 20%

Teradyne, Inc. has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 57.8% evidence confidence.

Photronics, Inc. looks inexpensive relative to peers or its own history, but its earnings trajectory has not yet earned the valuation signal.

Aehr Test Systems, Inc. has stronger price confirmation than earnings confirmation; that is a research prompt, not permission to chase.

How this score is built, and what the marks mean

Missing observations are not scored as bad. Their missing weight lowers confidence and pulls the final score toward neutral. PEG is not shown when the ratio cannot mean anything: the company must be making a profit, its price-to-earnings must be positive, and its three-year earnings growth must fall between 5% and 60%. Dividing a price multiple by a loss, or by growth measured off a tiny base, produces a number that looks precise and tells you nothing. Under relative strength, one mark per week shows the last 12 weeks: a mark is filled where the company led S&P 500 by 5% or more over the 13 weeks ending that week, which is the same test used everywhere on this site. Price stage places the company on the same six-step curve the sector itself is placed on — basing, turning, breaking out, leader, fading, asleep — read from how many weeks running it has led S&P 500 and whether that lead is widening or shrinking. It describes where the PRICE stands, not the earnings trajectory and not a recommendation, and it is left blank for a company whose weekly history is too short or too stale to read.

Investor read: ASML Holding N.V. is the scale benchmark; Ambarella, Inc. is the acceleration watch. Promote the challenger only if growth persists and converts into margin and returns.

This conclusion weakens if: ASML Holding N.V.'s growth falls below Ambarella, Inc.'s for two consecutive comparable reports while operating margin also compresses.

Revenue is compared on a common reported-currency basis. Growth is year-on-year, so seasonality does not masquerade as progress.

LeaderKLA Corporation · 41.2%

Gap11.1% versus #2 · ASML Holding N.V.

Persistence7/8 recent comparable periods

Coverage27/29 companies · 492 observations

Investor read: KLA Corporation sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

This conclusion weakens if: The next two comparable reports reverse the current margin change signal.

Operating margin compares operating profit with revenue. Improvement is measured in percentage points, not percentage growth.

Return On Capital Employed

Lam Research Corporation has the highest ROCE among the 29 Semiconductor Equipment & Materials companies compared here, at 15.5%. Teradyne, Inc. is next at 12.7%. Amtech Systems, Inc. has the highest ROCE change at +42.7 percentage points, so level and change sit with different companies. 28 of 29 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Lam Research Corporation leads ROCE at 15.5%, 2.8 percentage points above Teradyne, Inc.. Amtech Systems, Inc. has the strongest latest improvement at +42.7 percentage points. Read the leader beside the density of its reported history: a sparse high return is a candidate; a repeated high return is evidence of durability.

Investor read: Lam Research Corporation sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

This conclusion weakens if: The next two comparable reports reverse the current roce change signal.

ROCE asks how much operating return the business earns on the capital employed. Direction matters, but a single exceptional year should not be mistaken for durability.

Valuation Against Growth & Quality

Photronics, Inc. has the lowest PEG among the 29 Semiconductor Equipment & Materials companies compared here, at 0.43×. Veeco Instruments Inc. is next at 0.65×. Aehr Test Systems, Inc. has the lowest P/E at 12.4×, so level and change sit with different companies. 10 of 29 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Photronics, Inc. has the lowest comparable PEG at 0.43×, 33.8% below Veeco Instruments Inc.. Only 10 of 29 companies have earnings and growth steady enough for the ratio to mean anything, so no broad “cheapest stock” conclusion is defensible unless the current multiple, own-history position and growth durability agree.

Persistence0/8 recent comparable periods

Coverage10/29 companies · 82 observations

Investor read: Treat valuation as permission to investigate, never as a standalone reason to buy.

This conclusion weakens if: The next two comparable reports reverse the current p/e signal.

PEG is shown only when earnings are positive and three-year EPS growth is between 5% and 60%. It is recomputed consistently as the trailing P/E divided by that growth rate — reported earnings, never an expected-earnings multiple. On Indian companies it is shown only where the two data feeds agreed. Where any of that fails the ratio is left out rather than printed: a P/E divided by a loss, or by growth measured off a tiny base, is a number that looks precise and means nothing.

10 · before the conclusion, check the blind spots

What can make this comparison misleading?

This Semiconductor Equipment & Materials comparison names 4 specific ways its own evidence can mislead, all listed below. All 29 companies here report on comparable dates, so no rank carries a stale marker. A high growth rate can still be a low-base artefact.

Keep these limits visible

A high growth rate can be a low-base artefact. The page keeps level and change separate for that reason.
A high ROCE can be temporary or flattered by a small capital base. Read it beside margin, cash conversion and reinvestment.
The 4-Factor Sector Score ranks research priority, not portfolio action. Management quality, catalysts and risks need equally fresh evidence before capital is deployed.
An “all companies” line chart preserves completeness, but rank changes should be checked against reporting dates before drawing a conclusion.

11 · evidence and freshness

How was this comparison built?

This comparison is built from the reported filings of 29 Semiconductor Equipment & Materials companies, normalized to a common $ scale and a shared quarter axis of up to 20 quarters each. Fundamentals run through Jun 2026 and market data through 2026-08-04. A second data feed fills gaps only after identity and scale reconciliation, and missing observations are never interpolated.

Semiconductor Equipment & Materials company comparison FAQs

These 22 answers restate the Semiconductor Equipment & Materials comparison above in question form. Every one is computed from the same 29 companies and the same reported filings as the rankings and charts, current through Jun 2026. Price and relative-strength answers run through 2026-08-04. Nothing here is estimated, and none of it is a recommendation.

Is the Semiconductor Equipment & Materials sector outperforming S&P 500?

Which Semiconductor Equipment & Materials company is largest by revenue?

ASML Holding N.V. leads with revenue of $35,328 million, based on 17 of 29 comparable companies through Jun 2026.

Which Semiconductor Equipment & Materials company is growing fastest?

Ambarella, Inc. has the fastest current revenue growth at 27.8%, across 16 of 29 comparable companies.

Which Semiconductor Equipment & Materials company has the strongest 4-Factor Sector Score?

Teradyne, Inc. ranks first at 69.6/100 with 57.8% evidence confidence. The score prioritizes research; it is not a buy recommendation.

Which Semiconductor Equipment & Materials company has the lowest comparable PEG?

Photronics, Inc. has the lowest comparable PEG at 0.43, among 10 of 29 companies whose earnings and growth are steady enough for the ratio to mean anything.

How much history does this Semiconductor Equipment & Materials comparison include?

The page compares up to 20 reported quarters per company for fundamentals, returns and valuation, ending Jun 2026. Missing observations remain blank rather than being estimated.

How is the 4-Factor Sector Score calculated?

The four visible contributions add directly: growth and earnings up to 35 points, capital efficiency up to 25, valuation up to 20, and relative strength up to 20. Missing or stale evidence moves only the affected contribution toward neutral.

Which Semiconductor Equipment & Materials company is the biggest?

ASML Holding N.V. is the largest, with trailing-twelve-month revenue of $35,328 million, ahead of Applied Materials, Inc. at $29,024 million. That covers 17 of 29 companies with comparable reporting through Jun 2026.

Which Semiconductor Equipment & Materials company has the best profit margins?

KLA Corporation has the highest operating margin at 41.2%, from 27 of 29 comparable companies. Atomera Incorporated shows the biggest recent improvement, at +79084.1 percentage points. A high margin matters most when it is holding or rising, not when it is peaking.

Which Semiconductor Equipment & Materials company makes the most profit?

ASML Holding N.V. earns the most, at $10,399 million of trailing-twelve-month net profit, from 18 of 29 comparable companies. Applied Materials, Inc. has the fastest profit growth at 25.9%, though growth off a small or recovering profit base overstates how much has actually changed.

Which Semiconductor Equipment & Materials company earns the highest return on capital?

Lam Research Corporation leads on return on capital employed at 15.5%, across 28 of 29 companies. Read it beside the length of its reported history: a high return that repeats for years is evidence of a durable business, while a single high reading can be a small capital base or one good year.

Which Semiconductor Equipment & Materials stock is the cheapest?

On PEG — where a LOWER number is cheaper — Photronics, Inc. screens cheapest at 0.43×. Only 10 of 29 companies have earnings and growth steady enough for the ratio to mean anything, so this is not a sector-wide "cheapest stock" verdict. Cheap on a multiple is a reason to investigate, never a reason to buy on its own.

Is the Semiconductor Equipment & Materials sector beating the market?

Semiconductor Equipment & Materials has outperformed S&P 500 by 157.8% over the last 52 weeks and 9.6% over 13 weeks, measured on an equal-weight index of its current members. Inside the sector, 23 of 28 covered companies are beating the market on their own. Sector strength does not transfer evenly to every stock in it.

Which Semiconductor Equipment & Materials stock has the strongest price momentum?

Aehr Test Systems, Inc. has the strongest relative strength against S&P 500. Relative strength answers last, after growth, quality and valuation: price can move well before the fundamentals confirm it, and sometimes without them confirming at all.

Which Semiconductor Equipment & Materials company scores highest for research priority?

Teradyne, Inc. scores 69.6 out of 100 with 57.8% evidence confidence, from 24.3 points on growth and earnings, 18.4 on capital efficiency, 10.1 on valuation and 16.8 on relative strength. This ranks what deserves work next. It is not a buy recommendation, and management quality, catalysts and risk still need separate research.

How many Semiconductor Equipment & Materials companies does this comparison cover, and over what period?

It compares 29 listed companies over up to 20 reported quarters of fundamentals, ending Jun 2026, plus weekly price and relative-strength history. Membership is the full sector list — nothing is dropped for having thin data.

What is the total market cap of the Semiconductor Equipment & Materials sector?

The 29 Semiconductor Equipment & Materials companies on this page carry $1,956,813 million of combined market value. ASML Holding N.V. is the largest at $651,335 million, about 33% of the sector's total on its own. Market value moves with price, so this reading is dated 2026-08-04.

What is the Semiconductor Equipment & Materials sector's P/E ratio?

The median price-to-earnings ratio across the 29 Semiconductor Equipment & Materials companies on this page is 60×, measured on the 26 that report a comparable figure. A sector-level history for this multiple is not held here, so this is a cross-section of today, not a comparison with the sector’s own past. Figures are as of 2026-08-04.

How is the Semiconductor Equipment & Materials sector performing?

23 of the 28 covered Semiconductor Equipment & Materials companies are beating S&P 500 on Mansfield relative strength. The sector itself is 157.8% ahead of S&P 500 over 52 weeks on an equal-weight index of its current members. Readings are as of 2026-08-04.

How many Semiconductor Equipment & Materials stocks are listed in the US?

This comparison covers 29 listed Semiconductor Equipment & Materials companies in the US, each above the size floor the site applies. The full ranked list is on this page, with reported fundamentals through Jun 2026. Membership is the full industry list — nothing is dropped for having thin data.

Why are some values on this page blank?

A blank means that company did not report a comparable figure for that period, so nothing is shown. Missing observations are never interpolated, carried forward, or replaced with a similar-looking accounting line, and a company with missing evidence has its research score pulled toward neutral rather than being scored as bad.

Is this investment advice?

No. Every figure here is a deterministic calculation from reported company filings and market data, published for research. It contains no recommendation to buy or sell any security, does not account for your circumstances, and is not a substitute for advice from a licensed adviser.
