Dividend Aristocrats: The 25-Year Rule, and 12 Years of the Index Fund Against the S&P 500
Dividend Aristocrats are S&P 500 companies that have increased their total dividend per share every year for at least 25 consecutive years, the rule behind S&P Dow Jones Indices' S&P 500 Dividend Aristocrats index. On S&P's 31 Aug 2026 factsheet the index held 69 companies, each given the same weight.
A long record of dividend increases is one of the few company facts that anyone can check, and S&P Dow Jones Indices turned it into an index rule. The name suggests safety. The rules are narrower than the name, and a fund that has tracked the index since 2013 shows what the filter has and has not delivered.
How it works
The universe is the S&P 500. A company outside that index cannot be an Aristocrat in this sense, however long its record. S&P runs separate versions for mid caps, small caps and other regions; the MidCap 400 version, for example, asks for 15 years.
The test is the total dividend per share, year on year. The company must have raised it every year for at least 25 consecutive years. Holding the dividend flat for a year breaks the streak just as a cut does.
Size and trading floors apply. As of each rebalancing reference date, a company needs a float-adjusted market value of at least $3 billion and average daily value traded of at least $5 million over the prior three months.
Every member gets the same weight. A company worth $835.9 billion, the largest on the 31 Aug 2026 factsheet, counts the same as one worth $6.6 billion, the smallest. That is the opposite of the S&P 500 itself, where weight follows market value.
The list is rebuilt once a year and reweighted four times. The annual reconstitution takes effect after the close on the last business day of January, using data as of the end of December. Weights reset to equal after the close on the last business day of January, April, July and October.
The rules S&P applies
Beyond the 25-year test, the methodology dated July 2026 adds four conditions:
- A floor of 40 members. If fewer than 40 companies qualify, S&P fills the gap first with companies that have raised dividends for more than 20 years, in order of dividend yield, and then with the highest-yielding remaining S&P 500 members.
- A 30% sector cap. No single sector may exceed 30% of the index at the annual reconstitution. If one would, S&P adds further companies with 20-plus year records, again by yield, until the cap holds.
- Recent cutters are excluded. A company that reduced its dividend in the 12 months before the reference date is not considered.
- A monthly check. Members are reviewed each month for continued eligibility, and a company can be deleted between rebalancings, including through that monthly dividend review.
No additions happen between rebalancings, apart from spin-offs, so a company that reaches its 25th year of increases in March waits for the next January to join.
S&P’s consultation of 28 Aug 2026 does not touch this index. It proposes forecast-based screens for five other Aristocrats indices; the S&P 500 version is not on its list.
A worked example
Counting the years. Take a hypothetical S&P 500 company that raised its total dividend per share in every calendar year from 2001 through 2025. Each year’s total beat the year before, which makes 25 consecutive increases by the end of December 2025. It becomes eligible at the reconstitution that takes effect at the end of January 2026, provided it also clears the $3 billion and $5 million floors.
Equal weight in dollars. Put a hypothetical $10,000 into the 69 members at a quarterly reweight: $10,000 / 69 = $144.93 each, or 1.45% of the total.
Then let one member rise 25% while the others stand still. That holding grows to $144.93 x 1.25 = $181.16, and the portfolio to $10,000 + $36.23 = $10,036.23. Its weight is now $181.16 / $10,036.23 = 1.805%, or about 1.8%. At the next quarterly reweight it is cut back to one sixty-ninth.
That is the size of the drift on the 31 Aug 2026 factsheet. One month after the July reweight, the largest member weighed 1.8% and the ten largest together 16.7%, against 14.5% if all ten had sat exactly at an equal share.
Equal weight, and why it drifts
The reweight sells what rose and buys what fell. Every quarter the index trims members that have outgrown their equal share and tops up those that have shrunk. Over time that tilts the index toward smaller members and away from momentum, which is one reason it behaves differently from the S&P 500.
Membership is set by dividend history, not by what the market expects. A company that raised its payout for 30 years stays in even if its business is shrinking, until the streak breaks or it leaves the S&P 500.
The yield is modest. The factsheet puts the index’s indicated dividend yield at 2.46% on 31 Aug 2026. The rule selects for dividends that grow, not dividends that are large.
The original data
The data: ProShares S&P 500 Dividend Aristocrats (NOBL), one of the index-linked funds listed on S&P’s own page, against SPY, an S&P 500 fund. Both series are Yahoo Finance daily closes adjusted for dividends, which treats every dividend as reinvested. Yahoo’s NOBL history starts on 10 Oct 2013, so the comparison starts from the last close of October 2013 and runs to 25 Sep 2026. Fund returns are after each fund’s own costs, so they sit slightly below the indexes they track.
- $10,000 at the end of October 2013: $33,689 in NOBL and $54,589 in SPY by 25 Sep 2026.
- Per year over those 12.9 years: 9.9% for NOBL against 14.1% for SPY.
- Full calendar years ahead, 2014 to 2025: NOBL in 3 of 12 (2014, 2018 and 2022), SPY in the other nine.
- 2026 to 25 Sep: NOBL 7.3%, SPY 14.0%.
Two of the three years it led were down years for the market. In 2018 NOBL returned -3.3% against -4.6% for SPY, and in 2022 -6.5% against -18.2%; the third was 2014, 15.6% against 13.5%. In rising years it mostly trailed, and by a wide margin from 2023 to 2025: 8.1% against 26.2%, 6.7% against 24.9% and 6.8% against 17.7%. The full run from 2014 to 2025 for NOBL reads 15.6%, 0.4%, 11.6%, 21.0%, -3.3%, 27.4%, 8.4%, 25.5%, -6.5%, 8.1%, 6.7% and 6.8%; for SPY, 13.5%, 1.2%, 12.0%, 21.7%, -4.6%, 31.2%, 18.3%, 28.7%, -18.2%, 26.2%, 24.9% and 17.7%. Every year’s figures are in a CSV of NOBL and SPY calendar years. That record is one fund over one stretch of market history. It is not a forecast of the next stretch.
The falls tell a more mixed story than the name. Measured as each fund’s largest fall within the year, from a high adjusted close to a later low:
- 2020 crash: NOBL fell 35.4% (17 Jan to 23 Mar 2020); SPY fell 33.7% (19 Feb to 23 Mar 2020).
- 2022: NOBL fell 17.9% (4 Jan to 30 Sep 2022); SPY fell 24.5% (3 Jan to 12 Oct 2022).
A long dividend record did not protect the fund in the fastest crash of the period. In 2022 it did, by 6.6 percentage points. The same filter gave opposite results in two falls two years apart, which is why neither one settles the question, and why a single bad year for the market is a poor test of any screen. Both episodes are in a CSV of the 2020 and 2022 falls.
When it fails
When the streak is the whole case. A 25-year record describes the past board’s choices. A company can keep raising a payout it cannot afford for several years before the streak ends, and the index only removes it after the fact.
As downside protection. The 2020 figures above show the fund falling further than the S&P 500 fund in a sudden crash. Dividend history is not a volatility screen.
When back-tested history is read as a track record. The index launched on 2 May 2005. Its figures from 29 Dec 1989 to launch are a back-test, which S&P’s factsheet labels hypothetical and warns may reflect survivor and look-ahead bias.
As a list of the biggest dividend payers. With an indicated yield of 2.46% on 31 Aug 2026, the index is built for growing dividends. A high-yield screen picks a very different set of companies.
As a stand-in for the S&P 500. Equal weighting means the largest members count the same as the smallest, and companies that pay no dividend can never qualify. When a few very large companies lead the market, the index holds little or none of that move.

Dividend growth covers the strategy this index turns into a rule, including when a small growing payout overtakes a large flat one. Dividend yield explains the 2.46% figure and why a falling price inflates it, and survivorship bias explains the warning printed on the back-tested part of the index’s history. The screen for dividend stocks guide shows how to build a similar filter yourself.
I treat a 25-year dividend record as a filter, not a verdict. The streak says the board has chosen to raise the payout every year; it says nothing about whether next year’s raise is paid from earnings or from debt, so I check the payout ratio before I care about the streak.
