CMCSA against the whole market

Where CMCSA ranks among every stock and fund, and what across the market has done better.

How does CMCSA rank among all stocks?

This section ranks CMCSA on return, volatility, risk-adjusted return and worst decline against every stock worth at least $300 million with enough history. Where the comparisons with its popular alternatives show how CMCSA stacks up against its peers, these rankings show where it stands in the market as a whole.

Ranked against U.S.-listed stocks worth at least $300M that have enough history for each measure, so the count changes from row to row; smaller stocks are left out. Lower volatility and smaller declines rank higher.

What has beaten CMCSA 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). CMCSA sits where the dashed lines cross. Anything in the green box above and to the left earned more than CMCSA 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 CMCSA; faint dots are 90 more of the 1,337 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 CMCSA?

Investments that beat CMCSA 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 CMCSA 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 CMCSA'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 CMCSA 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 CMCSA'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× CMCSA's volatility counts as better.

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

What these numbers mean for CMCSA
Annual return
CMCSA lost 13.5% 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 $4,840. 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
CMCSA's volatility over the past 5 years was 27.7%, 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, CMCSA's return lands within 27.7% 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
CMCSA's Sharpe ratio over the past 5 years was -0.39, against 0.79 for the S&P 500, so CMCSA 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
CMCSA's worst fall from a peak to a low over the past 10 years was 60.2%, against 33.7% for the S&P 500. Losses and gains are not symmetric: climbing back from a 60.2% fall takes a 152% gain. Guide: Market crash risk and tail risk →
Correlation
Over the past 5 years, CMCSA's monthly returns had a correlation of 0.41 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 CMCSA instead: the lower it is, the more that option would diversify a CMCSA holding. Guide: Correlation and diversification →

CMCSA against its popular alternatives

The investments people most often weigh against CMCSA, compared period by period and year by year.

How do CMCSA's risk and return compare with its alternatives?

This map plots each investment's annual return over the past 5 years against its volatility, the size of its typical price swings. Investments toward the upper left earned more for a smoother ride, and those toward the lower right earned less for a rougher one. The dashed lines cross at CMCSA, which divides the map into what did better or worse on each measure.

Green points earned more than CMCSA with less volatility; red points earned less with more. Hover over a point for its figures. Total returns with dividends reinvested, annualized.

Has CMCSA consistently beaten its popular alternatives?

This section compares CMCSA 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 CMCSA helps separate lasting outperformance from a single strong stretch.

A green cell means the alternative earned more than CMCSA 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.

Risk and diversification

How CMCSA 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 CMCSA's worst declines?

A drawdown is the decline from a peak to the lowest point before a new high. This section presents CMCSA's five deepest drawdowns since it began trading in 1986, 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.

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

How did CMCSA do in stock market crashes?

This section measures how far CMCSA, 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.

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

How closely does CMCSA 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 CMCSA 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 CMCSA's: more upside, less downside or a higher capture ratio. Sorted by capture ratio.

What diversifies CMCSA?

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 CMCSA's. Because such investments tend not to fall at the same time, pairing CMCSA 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 CMCSA lost money. The last two columns show a portfolio that is 80% CMCSA and 20% the other investment, rebalanced monthly.
