Key findings

How much would $10,000 in TDG have grown?

This chart tracks a hypothetical $10,000 investment in TDG over the past 20 years, with dividends reinvested, alongside the same amount in the S&P 500, investments that ended ahead of TDG over the same span and TDG's popular alternatives, among those that traded for the entire period. A second view covers the past 5 years, the period the better options further down the page are judged on. It shows not only where each investment ended up but also how smooth or uneven the path was.

Note: TDG began trading on March 15, 2006, so the chart cannot reach back to the dot-com bust. It covers the most recent 20 years of TDG's record, starting at the end of September 2006.

What has beaten TDG on both return and risk?

Each dot is an investment, placed by how much it earned a year over the past 5 years (higher is better) and how much its price swung, its volatility (further left is calmer). TDG sits where the dashed lines cross. Anything in the green box above and to the left earned more than TDG with smaller swings, a better trade-off over this period on both counts. Past results are no promise, but a name in the box is worth a closer look.

Annual return is the annualized total return with dividends reinvested, and volatility the annualized swing in daily prices, both over 5 years. Labeled dots are the strongest picks from the table below and the names called out above, colored by how close they sit to TDG; faint dots are 56 more of the 83 in the green region (the strongest, one per fund family). 3,633 stocks and funds worth at least $500 million were screened.

Is there a better investment than TDG?

Investments that beat TDG over the past 5 years on return, volatility, drawdowns, consistency, crash losses or fees, from its popular alternatives out to the whole market.

How this works

The table below lists investments that beat TDG 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. It checks TDG's popular alternatives first, then the rest of its own and neighboring categories, then every stock and fund worth at least $500 million, and shows the strongest few in each group. The full list of those with a higher return and lower volatility than TDG follows the table.

Annual return is the annualized total return with dividends reinvested. Annual return, volatility and the Sharpe ratio cover 5 years; the worst decline covers the past 10 years. Green marks a better figure than TDG's. "On the frontier" means no other option shown or tested earned more with less volatility. Funds that hold the same thing are shown once. Beyond the popular alternatives, nothing with more than 1.5× TDG's volatility counts as better.

These figures cover the past 5 years. Green marks a better figure than TDG's.

What these numbers mean for TDG
Annual return
TDG returned 16.4% a year over the past 5 years with dividends reinvested, against 12.7% a year for the S&P 500. At that pace, $10,000 became about $21,400. Annual return is the steady yearly rate that would produce the same total result, so investments held over the same span compare fairly. Guide: What is performance and return? →
Volatility
TDG's volatility over the past 5 years was 28.0%, 1.6 times the S&P 500's 17.1%. Volatility measures how widely returns swing around their average: in roughly two years out of three, TDG's return lands within 28.0% of its average, either way. The higher it is, the rougher the ride and the harder it is to hold through a slump. Guide: Understanding and measuring risk (volatility) →
Sharpe ratio
TDG's Sharpe ratio over the past 5 years was 0.69, against 0.79 for the S&P 500, so TDG 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. Guide: Balancing reward with risk (Sharpe ratio) →
Worst decline
TDG's worst fall from a peak to a low over the past 10 years was 62.6%, against 33.7% for the S&P 500. Losses and gains are not symmetric: climbing back from a 62.6% fall takes a 168% gain. Guide: Market crash risk and tail risk →
Correlation
Over the past 5 years, TDG's monthly returns had a correlation of 0.61 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 TDG instead: the lower it is, the more that option would diversify a TDG holding. Guide: Correlation and diversification →

Has TDG consistently beaten its popular alternatives?

This section compares TDG with the investments people most often weigh against it, checking each one over eight periods from one month to ten years. Counting how often an alternative earned more than TDG helps separate lasting outperformance from a single strong stretch.

A green cell means the alternative earned more than TDG over that period. "Qualified" marks those that did so in at least 3 of 5 short-term periods and 2 of 3 long-term periods.

How did TDG do year by year?

This table shows each investment's total return in every full calendar year since 2007, along with where TDG ranked among its popular alternatives each year. Annual results reveal how consistently each one kept pace with TDG and how far its good and bad years diverged, detail that multiyear averages tend to smooth over.

Note: TDG began trading on March 15, 2006, so the table starts with 2007, its first full calendar year, and cannot show how it fared during the dot-com bust.

Newest year first. Green marks a year in which the fund came out ahead of TDG; gray means the two finished within a fraction of a point. The rank row places TDG among the alternatives that traded the full year; dark green is the top quarter and red the bottom quarter.

Risk and diversification

How TDG 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 TDG's worst declines?

A drawdown is the decline from a peak to the lowest point before a new high. This section presents TDG's five deepest drawdowns since it began trading in 2006, alongside the S&P 500's return over the same dates, and how long each took to recover. Together, these figures show how much an investor could have lost and how long it took to get back to even.

Note: TDG began trading on March 15, 2006, so this list cannot include the dot-com bust. The crash tests on this page show how older funds and the S&P 500 fared through those years.

Green means TDG fell less than the S&P 500 over the same dates. Based on daily closing prices with dividends reinvested.

How did TDG do in stock market crashes?

This section measures how far TDG, the S&P 500 and each alternative fell from peak to trough during every major market crash since 2000. A smaller decline means an investment held up better, and comparing results across crashes shows whether that resilience was consistent or a one-off.

Note: TDG began trading on March 15, 2006, so its row reads "Not yet trading" for the dot-com bust. The older alternatives and the S&P 500 show how those crashes played out.

Newest crash first. Each figure is the fund's deepest fall within the crash window; green means a smaller fall than TDG.

How closely does TDG move with the S&P 500?

Upside capture measures how much of the S&P 500's gains an investment kept in the months the market rose, and downside capture how much of its losses it took in the months the market fell. An investment that captures more of the gains than the losses has compounded ahead of the market over time. This section compares TDG with its popular alternatives on both measures, and on beta (how strongly each has moved with the market), over the past 10 years.

Monthly total returns over the past 10 years, measured against SPY. 100% capture or a beta of 1.00 means moving in line with the S&P 500. Green marks a better figure than TDG's: more upside, less downside or a higher capture ratio. Sorted by capture ratio.

What diversifies TDG?

Correlation measures how closely two investments move together, on a scale from 1 (in lockstep) through 0 (unrelated) to -1 (in opposite directions). This section lists large ETFs and stocks whose returns have had a low correlation with TDG's. Because such investments tend not to fall at the same time, pairing TDG with them can reduce a portfolio's overall swings.

Only ETFs with at least $1.0B in assets and stocks worth at least $10B, with a correlation below 0.5 over the past 5 years and a positive return, are included, ranked by Sharpe ratio; funds that hold the same thing are shown once. The year columns are the years in which TDG lost money. The last two columns show a portfolio that is 80% TDG and 20% the other investment, rebalanced monthly.

Common questions

What was TDG's worst drawdown?

TDG's deepest decline since it began trading in 2006 was 62.6%, from January to March 2020. It took 15 months from the low to climb back to its old high. Because TDG launched in March 2006, that record does not include the dot-com bust.

What were TDG's best and worst years?

Over 19 full calendar years, TDG's best year was 2019, when it returned 84.4%. Its worst was 2008, with a return of -25.7%.

Is there a better investment than TDG?

Among TDG's popular alternatives, RTX earned more than TDG with less volatility over the past 5 years: 18.6% a year at 24.3% volatility, against 16.4% a year at 28.0%. Looking beyond its popular alternatives, WAB (industrial machinery) earned more than TDG with less volatility over the past 5 years: 25.6% a year at 26.2% volatility, against 16.4% a year at 28.0%.

Is TDG more volatile than the S&P 500?

Yes. TDG's volatility over the past 5 years was 28.0%, 1.6 times the S&P 500's 17.1%. Volatility measures how widely returns swing around their average: in roughly two years out of three, TDG's return lands within 28.0% 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 TDG's Sharpe ratio?

TDG's Sharpe ratio over the past 5 years was 0.69, against 0.79 for the S&P 500, so TDG 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 TDG with the S&P 500?

Over the past 5 years, TDG's monthly returns had a correlation of 0.61 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 TDG instead: the lower it is, the more that option would diversify a TDG holding.

What are the best alternatives to TDG?

Of the 19 popular alternatives we compared, seven outperformed TDG in at least 3 of 5 short-term and 2 of 3 long-term timeframes, with dividends reinvested: DCO, HEI and MOG-A.

Did TDG outperform the S&P 500?

TDG finished ahead of the S&P 500 (SPY) in 15 of 19 full calendar years. In 2025, it returned +12.2%, against +17.7% for the index.

How did TDG do in stock market crashes?

TDG fell less than the S&P 500 (SPY) in two of the nine major crashes it has traded through, and further in six. The clearest case was the Covid crash, when TDG fell 61.7% and the S&P 500 fell 33.7%.

What diversifies TDG?

These had a low correlation with TDG over the past 5 years and still earned a positive 5-year return: among large ETFs, LVHI (correlation 0.43), DXJ (correlation 0.46) and EMLP (correlation 0.45); among large stocks, CAH (correlation 0.47), CLS (correlation 0.25) and FIX (correlation 0.33). A correlation near zero means the two have moved largely independently.
