Built by QuantCommons' quantitative engine, this page is about relative opportunity, not data on APH alone. It places APH (Amphenol Corporation) against 19 popular alternatives, its neighboring categories and the entire market of over 10,000 U.S.-listed stocks and ETFs, and surfaces what has done better on consistent outperformance, return for the risk taken, behavior in real market crashes and diversification. The result is a clearer view of where APH stands in the market, and of the alternatives worth a closer look.

Period covered: APH's full trading record, from November 1991 through September 2026. All returns include reinvested dividends. Data as of October 20, 2026.

## Key findings

- **Right now:** Not every peer went the same way. Over the past 6 months, MTRN (Materion) rose 32.6% and GLW (Corning) fell 19.7%. Over the past 6 months, APH rose 4.1% against 9.1% for the S&P 500 and 11.2% for the Nasdaq 100.
- **Stock or market?:** APH rose 5.5% over the past 3 months, in line with the electronic components ETF XLK (State Street Technology Select Sector SPDR ETF), which rose 5.7%. The S&P 500 rose 3.9%.
- **Past 1 to 3 years:** APH has outpaced the market, rising 25.6% over the past year against 15.8% for the S&P 500 and 17.9% for the Nasdaq 100. The same gap shows up over 3 years (311% against 89.3%). APH finished ahead of the S&P 500 in both 2024 and 2025.
- **Long term:** APH turned $10,000 into $106,000 over the past decade, against $42,100 in the S&P 500. APH's 10-year return of 965% puts it ahead of 95% of the stocks worth at least $300 million with that much history. The S&P 500 returned 321%.
- **In a crash:** Across seven sell-offs, APH has typically fallen 1.2 times as far as the S&P 500.
- **Diversification:** APH is more of the same, not a cushion: a correlation of 0.70 with the S&P 500 over 5 years and 0.71 with the total US market, more closely than 99% of stocks worth at least $300 million.
- **Better options**
  - **Popular alternatives:** NVDA (NVIDIA) and ANET (Arista Networks) were ahead of APH in most short and long periods, though with much bigger swings (51.9% and 49.0% volatility against 32.2%).
  - **Nearby categories and themes:** TSM (Taiwan Semiconductor Manufacturing, semiconductors) and ASX (ASE Technology Holding, semiconductors) were ahead of APH in most short and long periods.
  - **Whole market:** Few investments have done better on both counts: only two of the 3,633 stocks and funds worth at least $500 million earned more than APH with less volatility over the past 5 years, among them MCK (McKesson) and CAH (Cardinal Health).

## How much would $10,000 in APH have grown?

This chart tracks a hypothetical $10,000 investment in APH over the past 29 years, with dividends reinvested, alongside the same amount in the S&P 500, investments that ended ahead of APH over the same span and APH's popular alternatives, among those that traded for the entire period.

- $10,000 invested in APH at the end of September 1997 would have grown to $3,002,572 by September 2026, more than the $132,907 it would have become in SPY, an S&P 500 fund.
- Five of the eight other investments on the chart ended ahead of APH, and MNST finished highest, at $45,663,831.

### Is there a better investment than APH?

The table below lists investments that beat APH over the past 5 years on at least one of these measures: a higher annual return with lower volatility, a higher annual return at similar volatility, a similar return with lower volatility, a higher Sharpe ratio with a smaller worst decline, a higher total return in most periods from 3 months to 10 years, or smaller losses in recent market crashes.

- Among APH's popular alternatives, NVDA and ANET were ahead of APH in most short and long periods, though with much bigger swings (51.9% and 49.0% volatility against 32.2%).

### What diversifies APH?

Correlation measures how closely two investments move together, on a scale from 1 (in lockstep) through 0 (unrelated) to -1 (in opposite directions).

- Moving a fifth of the money in APH into MPC would have cut the portfolio's volatility by 14% over the past 5 years and raised its annual return (+37.3% for APH alone, +41.1% for the mix).
- Among large ETFs, LVHI, DXJ and EMLP have moved largely independently of APH over the past 5 years, with correlations of 0.42 or lower, and each still earned a positive 5-year return.
- CAH made money in four of the seven calendar years in which APH lost money.

## Common questions

### What was APH's worst drawdown?

APH's deepest decline since it began trading in 1991 was 63.6%, from August to November 2008. It took 24 months from the low to climb back to its old high.

### What were APH's best and worst years?

Over 29 full calendar years, APH's best year was 1997, when it returned 150%. Its worst was 2008, with a return of -48.2%.

### Is there a better investment than APH?

Among APH's popular alternatives, NVDA and ANET were ahead of APH in most short and long periods, though with much bigger swings (51.9% and 49.0% volatility against 32.2%). Looking beyond its popular alternatives, TSM (semiconductors) and ASX (semiconductors) were ahead of APH in most short and long periods.

### Is APH more volatile than the S&P 500?

Yes. APH's volatility over the past 5 years was 32.2%, 1.9 times the S&P 500's 17.1%. Volatility measures how widely returns swing around their average: in roughly two years out of three, APH's return lands within 32.2% of its average, either way. The higher it is, the rougher the ride and the harder it is to hold through a slump.

### What is APH's Sharpe ratio?

APH's Sharpe ratio over the past 5 years was 1.07, against 0.79 for the S&P 500, so APH earned more for each unit of risk than an index fund did. The Sharpe ratio is the return earned above cash for each unit of volatility: two investments with the same return are not equal if one got there with far bigger swings.

### How correlated is APH with the S&P 500?

Over the past 5 years, APH's monthly returns had a correlation of 0.70 with the S&P 500. Correlation runs from 1 (moving in lockstep) through 0 (unrelated) to −1 (moving in opposite directions). They often move together: some diversification next to an index fund, but not a cushion. In the table, the correlation column measures each option against APH instead: the lower it is, the more that option would diversify a APH holding.

### What are the best alternatives to APH?

Of the 19 popular alternatives we compared, two outperformed APH in at least 3 of 5 short-term and 2 of 3 long-term timeframes, with dividends reinvested: NVDA and ANET.

### Did APH outperform the S&P 500?

APH finished ahead of the S&P 500 (SPY) in 23 of 29 full calendar years. In 2025, it returned +97.6%, against +17.7% for the index.

### How did APH do in stock market crashes?

APH fell less than the S&P 500 (SPY) in none of the ten major crashes it has traded through, and further in seven. The clearest case was the dot-com bust, when APH fell 60.7% and the S&P 500 fell 47.5%.

### What diversifies APH?

These had a low correlation with APH over the past 5 years and still earned a positive 5-year return: among large ETFs, LVHI (correlation 0.32), DXJ (correlation 0.42) and EMLP (correlation 0.38); among large stocks, CAH (correlation 0.40), MCK (correlation 0.20) and MPC (correlation 0.10). A correlation near zero means the two have moved largely independently.
