The line below covers up to 5.2 years and opens on the 5Y view; the buttons cut it shorter. Over the last two years (104 weeks) this industry is 100% ahead of S&P 500. Earnings across its companies grew 38% on average over the last four reported quarters.

Price and the fundamentals both up. 1 of 30 companies ahead of S&P 500 by 5% or more over three months. 3 are 20% or more behind over a year while earnings grew 20% or more.

Not ahead of S&P 500 on the three-month view this week; 9 of the 30 companies in the industry index above their 200-day average (11 fewer than four weeks earlier); 1 of those 30 ahead of S&P 500 by 5% or more over three months (4 fewer than four weeks earlier); earnings rising at 23 of the 30 that report earnings.

Participation is shrinking, 5 → 1 of 30 over four weeks, after being ahead of S&P 500. Price-only fade, 23 of 30 members have higher trailing twelve-month earnings than a year ago, so the fade is in the price, not in the earnings.

Both lines start at 200 in the same week, so the gap between them tells the story: the industry line is an equal-weighted index of its 30 companies. The bars underneath are trailing 12-month earnings per share, one bar per reported quarter, each member set to 100 at the start and the industry taking the middle value, so a price line pulling away from flat bars means the market is paying more for the same earnings. A bar turns grey when that figure is lower than the quarter before. The rules are fixed and the same 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 or tap any point to read both values and the gap.

Electronic Components has done better than the S&P 500 by 23.9% over the last 52 weeks. Over 13 weeks the gap is a shortfall of 18.8%. Richardson Electronics, Ltd. is the strongest against the sector itself at +32.6%.

Electronic Components has done better than the S&P 500 by 23.9% over 52 weeks, but is 18.8% behind over the last 13 weeks. 8 of 30 companies we track are beating the S&P 500 on relative strength (how a share price has done against the index over recent months), and 10 of 30 are ahead of the industry itself.

A score that ranks each company against the others in its industry. The four parts shown always add up to the total: Growth & earnings (35), Capital efficiency (25), Valuation (20), and Relative strength (20). Missing or old evidence affects only its own part, never as a hidden adjustment.

Amphenol Corporation has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 85.3% evidence confidence.

Syntec Optics Holdings, Inc. has the strongest one-year price move in Electronic Components at +109.2%. Richardson Electronics, Ltd. leads on relative strength against the S&P 500, at +24.5%. 8 of 30 companies we track are ahead of the index on that measure. Every line covers 314 weekly closes through 4 November 2026.

Price and relative strength

Price · same starting point: Every company, the sector's own index and S&P 500 all start level on the left edge of the window, so only the distance between the lines counts: the highest line has risen the most since then, and the chart at the top of this page is drawn the same way. It opens on one year; the buttons beside it stretch that to three or five.

RS vs S&P 500: How far ahead of or behind S&P 500 each company has been running, measured against its own recent average of that comparison, so the flat line at zero IS S&P 500: above it the company is beating the market, below it the market is beating the company. It opens on one year.

RS vs sector: The same measure taken against Electronic Components itself instead of the whole market, so the flat line at zero is the sector: above it the company is beating its own peers, which is the sharper test of the two. It opens on one year.

Jabil Inc. has the highest Revenue among the 30 Electronic Components companies compared here, at $35,954 million. Amphenol Corporation is next at $33,047 million. LightPath Technologies, Inc. has the highest Revenue growth at 97.2%, so level and change sit with different companies. 28 of 30 companies report a comparable reading, the latest through Sep 2026.

What the numbers say: Jabil Inc. is the largest at $35,954 million, 8.8% ahead of Amphenol Corporation. LightPath Technologies, Inc.'s growth is 97.2% from a $71 million base, with 19 reported quarters out of the last 20. Fast growth from a smaller base is not yet the same as proven size.

What this means: Jabil Inc. is the size to compare against; LightPath Technologies, Inc. is the one growing fastest. The faster grower has to keep that growth and turn it into margin and returns before it counts as more than a fast start.

This conclusion weakens if: Jabil Inc.'s growth falls below LightPath Technologies, 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.

All-company data · latest reported quarter

In every all-company table on this page, each figure is the company’s latest single reported quarter. The rankings above them use trailing-twelve-month or current-market values, so a company can legitimately show a different number in each.

Revenue shows both size and speed. A large company can absorb shocks and pay for wide distribution; faster growth can mean market-share gains, new capacity or stronger demand. The best sign is usually growth that lasts without hurting margins and returns.

Vicor Corporation has the highest OPM among the 30 Electronic Components companies compared here, at 36.6%. Universal Display Corporation is next at 35.3%. Ouster, Inc. has the highest Margin change at +45.3 percentage points, so level and change sit with different companies. 30 of 30 companies report a comparable reading, the latest through Sep 2026.

What the numbers say: Vicor Corporation leads opm at 36.6%; Ouster, Inc. leads margin change at +45.3 percentage points.

What this means: Vicor Corporation sets the level to compare against; the company improving fastest needs another report to confirm the change.

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.

Amphenol Corporation has the highest Net profit among the 30 Electronic Components companies compared here, at $5,987 million. TE Connectivity plc is next at $3,016 million. Celestica Inc. has the highest Profit growth at the 100% top of the scoring scale, so level and change sit with different companies.

What the numbers say: Amphenol Corporation earns the most, $5,987 million of profit over the last 12 months, 98.5% above TE Connectivity plc. Celestica Inc. shows at least 100% on the scoring scale (107.2% in full) growth from a profit base of $1,117 million. A fast rate from a small base matters less than a large profit that keeps coming.

What this means: Amphenol Corporation sets the level to compare against; the company improving fastest needs another report to confirm the change.

This conclusion weakens if: The next two comparable reports reverse the current profit growth signal.

Net profit is the residual after operating costs, interest and tax. Growth off a loss or near-zero base is excluded from the fastest-grower rank.

Celestica Inc. has the highest ROCE among the 30 Electronic Components companies compared here, at 38.2%. Jabil Inc. is next at 31.9%. Kopin Corporation has the highest ROCE change at +51.2 percentage points, so level and change sit with different companies. 30 of 30 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Celestica Inc. leads ROCE at 38.2%, 6.3 percentage points above Jabil Inc. A high return reported once may be one good year; a high return reported year after year shows a lasting business.

What this means: Celestica Inc. sets the level to compare against; the company improving fastest needs another report to confirm the change.

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.

Celestica Inc. has the lowest PEG among the 30 Electronic Components companies compared here, at 0.59×. Littelfuse, Inc. has the lowest P/E at −1419.1×, so level and change sit with different companies. 20 of 30 companies report a comparable reading, the latest through Jun 2026. Its PEG series carries 5 reported observations across the 20-quarter window.

What the numbers say: Celestica Inc. has the lowest comparable PEG at 0.59×, 0% below Richardson Electronics, Ltd. That would need today's multiple, the company's own history and steady growth to agree.

What this means: A low valuation is a reason to look closer at the business, not a conclusion on its own.

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 worked out the same way every time, as the P/E on the last 12 months of reported earnings divided by that growth rate, never on expected earnings. 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.
