Built by QuantCommons' quantitative engine, this page is about relative opportunity, not data on T alone. It places T (AT&T Inc.) against 18 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 T stands in the market, and of the alternatives worth a closer look.

Period covered: T's full trading record, from October 1986 through September 2026. All returns include reinvested dividends. Data as of October 20, 2026.

## Key findings

- **Right now:** T has gone against the market, falling 8.2% over the past 6 months while the S&P 500 rose 9.1%. Its integrated telecommunication peers split over the past 6 months: VOD (Vodafone Group Public) rose 3.4%, while CMCSA (Comcast) fell 22.6%.
- **Stock or market?:** T held up far better than its industry: it rose 8.0% over the past 3 months while the integrated telecommunications ETF IYZ (iShares U.S. Telecommunications ETF) fell 1.4%. The S&P 500 rose 3.9%.
- **Past 1 to 3 years:** Over the past year, T fell 5.9% while the S&P 500 rose 15.8%. The same gap shows up over 3 years (77.2% against 89.3%).
- **Long term:** T turned $10,000 into $16,100 over the past decade, against $42,100 in the S&P 500.
- **In a crash:** In the 2022 bear market, T fell 29.2%, against 24.5% for the S&P 500. That was more than TMUS (T-Mobile US, 12.1%) but less than VZ (Verizon Communications, 33.2%).
- **Diversification:** Against the S&P 500, T has a correlation of 0.14 over 5 years, less closely than 92% of stocks worth at least $300 million. Next to an index fund it is a real diversifier. T's link to the S&P 500 has loosened: a correlation of 0.14 over the past 5 years, down from 0.63 in the 5 years before.
- **Better options**
  - **Popular alternatives:** KT earned more than T with less volatility over the past 5 years: 13.1% a year at 22.6% volatility, against 9.8% a year at 25.2%.
  - **Nearby categories and themes:** MSI (Motorola Solutions, communications equipment) earned more than T with less volatility over the past 5 years: 14.8% a year at 23.6% volatility, against 9.8% a year at 25.2%.
  - **Whole market:** 328 of the 3,633 stocks and funds worth at least $500 million earned more than T with less volatility over the past 5 years, among them VTI (Vanguard Morningstar Total Stock Market ETF), VOO (Vanguard S&P 500 ETF) and BRK-B (Berkshire Hathaway).

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

This chart tracks a hypothetical $10,000 investment in T over the past 29 years, with dividends reinvested, alongside the same amount in the S&P 500, investments that ended ahead of T over the same span and T's popular alternatives, among those that traded for the entire period.

- $10,000 invested in T at the end of September 1997 would have grown to $65,217 by September 2026, less 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 T, and RCI finished highest, at $210,974.

## Risk and diversification

How T has fallen, how it held up in crashes beside the S&P 500 and its popular alternatives, and what moves independently of it.

### What were T's worst declines?

A drawdown is the decline from a peak to the lowest point before a new high.

### How closely does T move with the S&P 500?

- TMUS took just 37% of the S&P 500's losses, against 62% for T, while still keeping 63% of its gains.
- Seven of the 18 popular alternatives had a higher capture ratio (upside capture divided by downside capture) than T's 0.76, led by TMUS, CSCO and TDS.

### What diversifies T?

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 T into SMH would have cut the portfolio's volatility by 20% over the past 5 years and raised its annual return (+10.1% for T alone, +17.1% for the mix).
- Among large ETFs, LVHI, DXJ and EMLP have moved largely independently of T over the past 5 years, with correlations of 0.49 or lower, and each still earned a positive 5-year return.
- FIX made money in six of the nine calendar years in which T lost money.

## Common questions

### What was T's worst drawdown?

T's deepest decline since it began trading in 1986 was 63.9%, from November 2000 to March 2003. It took about four years from the low to climb back to its old high.

### What were T's best and worst years?

Over 29 full calendar years, T's best year was 2006, when it returned 55.6%. Its worst was 2002, with a return of -27.6%.

### Is there a better investment than T?

Among T's popular alternatives, KT earned more than T with less volatility over the past 5 years: 13.1% a year at 22.6% volatility, against 9.8% a year at 25.2%. Looking beyond its popular alternatives, MSI (communications equipment) earned more than T with less volatility over the past 5 years: 14.8% a year at 23.6% volatility, against 9.8% a year at 25.2%.

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

Yes. T's volatility over the past 5 years was 25.2%, 1.5 times the S&P 500's 17.1%. Volatility measures how widely returns swing around their average: in roughly two years out of three, T's return lands within 25.2% 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 T's Sharpe ratio?

T's Sharpe ratio over the past 5 years was 0.50, against 0.79 for the S&P 500, so T earned less 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 T with the S&P 500?

Over the past 5 years, T's monthly returns had a correlation of 0.14 with the S&P 500. Correlation runs from 1 (moving in lockstep) through 0 (unrelated) to −1 (moving in opposite directions). They are only loosely linked, which makes it a real diversifier next to an index fund. In the table, the correlation column measures each option against T instead: the lower it is, the more that option would diversify a T holding.

### What are the best alternatives to T?

Of the 18 popular alternatives we compared, two outperformed T in at least 3 of 5 short-term and 2 of 3 long-term timeframes, with dividends reinvested: CSCO and KT.

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

T finished ahead of the S&P 500 (SPY) in 13 of 29 full calendar years. In 2025, it returned +14.0%, against +17.7% for the index.

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

T fell less than the S&P 500 (SPY) in seven of the ten major crashes it has traded through, and further in two. The clearest case was the 2008 financial crisis, when T fell 44.4% and the S&P 500 fell 55.2%.

### What diversifies T?

These had a low correlation with T over the past 5 years and still earned a positive 5-year return: among large ETFs, LVHI (correlation 0.49), DXJ (correlation 0.15) and EMLP (correlation 0.38); among large stocks, CAH (correlation 0.01), CLS (correlation -0.07) and FIX (correlation -0.17). A correlation near zero means the two have moved largely independently.
