Microsoft stock returned less than the S&P 500 over the five years ending June 30, 2026, in Microsoft’s latest company-reported comparison. With dividends reinvested and both investments starting at 100 on June 30, 2021, Microsoft ended at 143.49 and the S&P 500 at 187.57. That is a historical comparison for those dates—not a forecast—and the ending values alone cannot show which had greater volatility or the larger peak-to-trough loss.

Both figures use the same June 30, 2021–June 30, 2026 dates and include reinvested dividends, according to Microsoft’s FY2026 annual report. The percentage returns are calculated from the report’s starting value of 100 and ending values; they are not separate percentages quoted by Microsoft. They are before taxes, fees, and investor-specific effects.

The 44.08-point difference between the endpoints is meaningful on the normalized scale, but it is not a risk score. It says how far apart the two ending values were after five years. It does not say whether Microsoft lagged throughout the period, whether the index led only near the end, or how much either investment fell before recovering.
Did Microsoft beat the S&P 500 over five years?
No. In Microsoft’s reported five-year comparison, the S&P 500 had the higher cumulative total return: 87.57%, versus 43.49% for Microsoft stock.

The comparison begins at 100 for each investment on June 30, 2021. By June 30, 2026, the Microsoft value was 143.49 and the S&P 500 value was 187.57. In dollar terms, a hypothetical $100 investment would therefore have gained $43.49 in Microsoft and $87.57 in the index over that specific period, assuming the report’s dividend-reinvestment treatment. The gap between the reported ending values is 44.08 points, or $44.08 on that hypothetical $100 starting basis.
These are cumulative returns across the full five-year window, not annual returns. They do not mean that either investment rose by the same amount each year, nor do they describe the path between the start and end dates. A larger cumulative result for one historical period says nothing certain about which investment will perform better in another period.
For a reader asking “Microsoft stock vs. S&P 500 long-term returns,” the precise answer is therefore date-specific: the index won in this five-year total-return comparison, but that result should not be generalized to every five-year period or to the future.
What exactly does this five-year return comparison measure?
It compares the change in value of two investments over identical dates, with dividends reinvested. Matching dates and return definitions matters: a total-return figure should be compared with another total-return figure, not with a price-only index series.
Microsoft’s annual-report chart sets both series to 100 on June 30, 2021 and reports their cumulative values at June 30, 2026. The chart includes reinvested dividends. Converting an ending value into a cumulative return is straightforward:
Cumulative return = (ending value ÷ starting value − 1) × 100

- S&P 500: (187.57 ÷ 100 − 1) × 100 = 87.57%.
The 100-point starting value is a normalized comparison, not a claim that an actual share or index unit cost $100. It puts both performance series on the same scale so their changes can be compared directly.
Dividend treatment is important because a price-return series reflects price changes, while a total-return series also accounts for dividends or other cash distributions. S&P Dow Jones Indices explains the distinction and notes that index dividend treatment is not identical to how an index-linked product reinvests dividends to buy shares. Comparing Microsoft’s dividend-reinvested total return with an S&P 500 price-only return would mix unlike measures and could mislead.

If you want an annualized equivalent for these endpoints, the compound annual growth rate can be calculated as (ending value ÷ starting value)1/5 − 1. Using the reported values gives approximately 7.5% a year for Microsoft and 13.4% a year for the S&P 500. These are mathematical annualized equivalents of the five-year endpoints, not annual observations reported by Microsoft. They do not reveal how returns varied from year to year and should not be confused with annualized volatility.
What is different about Microsoft stock and the S&P 500?
Microsoft stock represents exposure to one company. The S&P 500 is an index of 500 leading companies and covers approximately 80% of available U.S. market capitalization, according to S&P Dow Jones Indices’ index overview.

The index is float-adjusted market-cap weighted, meaning companies with larger eligible market values have greater influence on its movements. It is broad, but it is not an equal-weight basket in which every company contributes the same amount. Its roster can also change as companies are added or removed under the index’s rules; the S&P 500 and the Dow overview provides context on the index.
That structure changes the type of exposure, not the certainty of the outcome. A single-company position is more directly tied to that issuer’s results and prospects as well as broad market movements. An index spreads exposure across many companies, but its constituents can fall together, and its largest constituents can have an outsized effect because of its weighting method.
Microsoft’s Savings Plus 401(k) Plan Summary Plan Description, dated January 1, 2025, states: “The absence of diversification in Microsoft Stock creates an additional element of risk for that investment.” This is a statement in a plan document, not a current forecast or a quantified measurement of Microsoft’s share-price risk. The same document cautions that “historical performance is no guarantee of future performance.”
There is also a scope difference. Microsoft is a publicly traded issuer whose operating, financial, regulatory, currency and competitive developments can affect one share price. The S&P 500 is a benchmark portfolio representing many issuers, with exposure that changes as index membership and float-adjusted weights change. The index can therefore be diversified without being static.
Is Microsoft stock riskier than the S&P 500?
The available evidence supports a structural distinction: Microsoft is one issuer, while the S&P 500 holds many companies. It does not support a numerical comparison of their volatility or maximum drawdown for the five-year period.
Microsoft’s annual-report endpoints show where each series began and ended, but not the daily or monthly observations between those dates. Two investments can finish at the same value after very different paths—one could have moved relatively steadily while another suffered larger interim losses. The endpoint table therefore cannot establish which had the rougher ride or the more severe temporary decline.

To quantify risk fairly, an analyst would need aligned periodic total-return data for both investments over the same period, and would need to state the calculation method and dates. Two useful measures are:
- Annualized volatility: a statistical summary of how much periodic returns varied, scaled to a yearly basis. It describes variability, not whether returns were positive or negative overall.
- Maximum drawdown: the largest percentage decline from a prior peak to a subsequent trough during the selected period. It depends on the observed path and the chosen start and end dates.
A comparison should report those measures only when they have been calculated from matching periodic total-return series. No such aligned daily or monthly series is provided in the reported annual-return endpoints, so assigning volatility or drawdown figures here would imply precision the data do not support.

Diversification should not be confused with protection from loss. The S&P 500’s broad company coverage changes the concentration of exposure; it does not prevent market-wide declines or guarantee a smaller loss in every interval. Conversely, the one-company structure identifies a concentration risk, but by itself does not tell a reader how large Microsoft’s realized volatility or drawdown was in a particular window.
Microsoft’s FY2026 annual report separately identifies foreign-exchange, interest-rate, credit and equity-price risks for the company. Those disclosures describe business and financial-statement exposures. They are not a substitute for a time series of MSFT share returns, and they should not be presented as evidence that the stock had a specific volatility or drawdown.
How can you compare long-term returns fairly?
Use a like-for-like comparison: same dates, same return type, explicit dividend assumptions, and a clear distinction between an index and an investable product that tracks it.
- Choose and state the period. The company-reported comparison here runs from June 30, 2021 through June 30, 2026. A result for another start or end date may differ materially. Even moving the start by a few trading days can change the outcome because prices and distributions are different on different dates.
- Match the return definition. Compare total return with total return if dividends are included. Do not pair Microsoft’s dividend-reinvested result with a price-only S&P 500 figure.
- Show both the starting and ending values. Giving the common baseline of 100 and the respective endpoints makes the cumulative-return calculation transparent.
- Name the benchmark series. Specify whether an S&P 500 result is price return or total return and how dividends are treated. “The S&P 500” alone may not identify the particular return series used.
- Separate index performance from investor results. An index level is not the net return an investor receives through a fund. Product expenses, taxes, and tracking differences are not represented by the index level; the index’s dividend calculation also does not necessarily match the way a product handles cash distributions.
- Keep historical performance separate from expectations. Past results are a record for a stated period, not a prediction. Microsoft’s plan document explicitly warns that historical performance does not guarantee future performance.
For a risk comparison, add matched periodic observations and explain the dates and calculation method for each measure. A chart should plot actual observed periodic total-return values; connecting a few annual endpoints with a smooth line would create an unobserved path and could disguise interim losses.

A separate risk table can list annualized volatility and maximum drawdown only when the underlying periodic data are available. Adding a concentration row—one issuer versus 500 companies—helps readers understand why return and risk are different questions.
What costs and investor effects are missing?
The reported figures are not a statement of what every investor earned. They are benchmark-style historical values before taxes, fees and individual account effects. A fund or exchange-traded product seeking S&P 500 exposure generally has an expense ratio and may not replicate the index exactly. Trading costs, cash timing, withholding, tax treatment and tracking differences can affect an investor’s result. A person who owned Microsoft shares would likewise face commissions or spreads where applicable, taxes on sales or distributions, and a purchase date that might not match June 30, 2021.

Dividend reinvestment is an assumption, not a guarantee that a particular account reinvested on the same terms. S&P Dow Jones Indices notes that index dividend calculations and the mechanics used by an index-linked product are not identical concepts. Therefore, a published total-return index and a fund’s net asset value can diverge even when the fund is designed to track the same benchmark.
These details matter most when comparing a real portfolio with a normalized chart. Use the chart to answer the historical benchmark question, then review the specific product’s fees, tax treatment and tracking record for an investor-level decision.
What the annual report does—and does not—tell you
The report is useful for answering a bounded question: how did Microsoft and the S&P 500 compare in cumulative total return over the five years ending June 30, 2026, on a common starting-value basis? On that basis, the index outperformed Microsoft.
It does not show the exact sequence of gains and losses within those five years, explain what caused the return gap, or establish which investment is appropriate for a particular person. It also does not provide after-tax or after-fee investor returns. Those require different information and, for investor outcomes, depend on the specific account, product, and circumstances.
Microsoft’s annual report separately discusses company exposures to foreign-exchange, interest-rate, credit, and equity-price risks. Those disclosures concern the company’s business and financial statements; they are not a measurement of MSFT share-price volatility and should not be substituted for a stock-return risk series.
Nor does the report’s table prove that the S&P 500 is always safer. A diversified index can experience a broad market decline, and its market-cap weighting means its largest constituents influence results more than smaller constituents. The table establishes one historical outcome, not a universal ranking of return, safety or suitability.
How should you interpret the result?
Read the answer narrowly: for the June 30, 2021–June 30, 2026 period in Microsoft’s FY2026 report, the S&P 500 produced the higher cumulative total return. The comparison is most useful when its dates, dividend reinvestment, starting value, and benchmark definition remain visible.
Do not infer a future winner, a risk ranking based on volatility, or a fund investor’s realized return from the two ending values. The meaningful structural contrast is concentration: one company versus a broad, market-cap-weighted index. That distinction can inform a comparison, but the evidence here does not quantify the two investments’ full risk paths.

If you update the comparison later, preserve the methodology: use a new common end date, identify the applicable Microsoft report, match total-return definitions, and do not splice annual endpoints into a fabricated daily path. A changed window may produce a changed winner without contradicting the FY2026 result.
Bottom line
Microsoft did not beat the S&P 500 in the five-year total-return comparison ending June 30, 2026. A normalized $100 grew to $143.49 in Microsoft and $187.57 in the index, with dividends reinvested. The result is historical and date-specific. Microsoft represents concentrated single-company exposure; the S&P 500 represents a diversified, float-adjusted market-cap-weighted basket. To compare risk numerically, obtain aligned periodic total-return data rather than relying on the two endpoints.

Can I expect Microsoft to keep trailing the S&P 500?
No conclusion about future relative performance follows from this five-year record. Microsoft’s plan document says historical performance is no guarantee of future performance, and the reported endpoints are not a forecast.
Why might my S&P 500 fund return differ from the index figure?
An index level does not include the expenses, taxes, or tracking differences of a specific fund. Dividend handling can differ as well, so an investor’s product return may not match an index’s published total-return series.
Does this comparison show which investment had the bigger losses along the way?
No. The start and end values do not reveal the interim path. Establishing the largest peak-to-trough decline requires periodic return or value observations across the same dates.
Is the S&P 500 an equal-weight index?
No. S&P Dow Jones Indices describes it as float-adjusted market-cap weighted, so larger eligible companies have greater influence on its movements.

It is the June 30, 2026 ending value of a series that started at 100 on June 30, 2021, with dividends reinvested. It represents a 43.49% cumulative gain on that normalized basis, not a quoted share price.
The Bottom Line
Bottom line: From June 30, 2021 to June 30, 2026, $100 with dividends reinvested became $143.49 in Microsoft and $187.57 in the S&P 500. The index won that historical window, while the available endpoints do not establish which investment had greater volatility or drawdown.
