How this list is ranked
- Universe. The 100 largest S&P 500 companies by market value (price times diluted shares), limited to those with confidence High and financial health of at least 60.
- Score. The X-Ray score (0 to 100) blends valuation, growth, profitability, financial health and dividends, with each lens ranked within the sector.
- Order. Sorted by X-Ray score; ties go to the higher financial-health score.
- Data. Scores come from company filings with the SEC and our own fair-value models. Every figure is our own calculation, dated 22 Oct 2026.
- Limits. Scores describe the past and the present, not the future. A company with less history gets a lower confidence label. Different rules give a different order, which is why the rules are printed here.
Why a ranking by stated rules and not a "best" label: the order changes with the rules, so the rules are published next to the list. See also how the X-Ray Score works.
What "blue chip" means here
There is no official blue-chip category, so this page defines it. We take the 100 largest S&P 500 companies by market value (share price times diluted shares) among those we score, then keep only the ones with High confidence and a financial-health score of at least 60. 26 of the 100 pass. The survivors are ranked on the X-Ray score. Market value is used only to choose the 100; it is not shown, because the point of the page is quality within the largest companies, not size.
Size is not safety
The largest companies are not immune from large falls, and some of the biggest names on the S&P 500 do not make this list because their balance sheets or filing history do not meet the filter. The health score looks at accounting strength (the Piotroski F-score, the Altman Z-score, interest cover and liquidity, ranked within sector); it says nothing about how far the share price could fall in a market sell-off.
What the current top ten shows
The leader is Nvidia Corp, followed by Intuitive Surgical Inc, Microsoft Corp. The ten come from these sectors: 5 in Information Technology, 2 in Communication Services, 1 in Health Care, 1 in Consumer Staples, 1 in Financials. Our fair-value models label 0 undervalued, 10 fair and 0 overvalued, so a place on a blue-chip list says nothing about whether the price is attractive.
Questions about these US blue-chip stocks
Is blue chip an official category?
No. It is an informal label for large, established companies. This page uses a stated rule, the 100 largest S&P 500 companies by market value that also pass a health and confidence filter, so you can see exactly what is and is not included.
Why are some very large companies missing?
Either they are not in the 100 largest among the companies we score, or they fail the filter: confidence must be High and financial health at least 60.
Does the list include companies outside the S&P 500?
No. We score S&P 500 companies from SEC filings; other companies have no X-Ray score yet.
Why is there no dividend requirement?
Many large, healthy companies pay little or nothing. Income is covered by the dividend list, which applies a yield band and a payout test.
