Quick answer
Blue-chip stocks are shares in large, well-known companies with a solid history of growth, and they generally pay dividends [1]. The label is informal: there is no official list or test.
#What makes a stock blue-chip?
Investor.gov describes blue chips as shares in large, well-known companies with a solid history of growth that generally pay dividends [1]. In practice the term points to a few shared traits rather than a rulebook. "Large" usually means large by market value: FINRA's common size bands call $10 billion to $200 billion large-cap and $200 billion or more mega-cap, while noting that the dividing lines can vary [2].
#How does the Dow Jones Industrial Average use the term?
One well-known blue-chip index is the Dow. S&P Dow Jones Indices describes it as a price-weighted measure of 30 U.S. blue-chip companies, covering all industries except transportation and utilities [4]. Price-weighted means higher-priced shares carry more weight. See the Dow Jones Industrial Average profile.
Worked example
Why price-weighting matters
In a price-weighted index, a $1 move counts the same whichever stock makes it. Compare a $1 rise in a $400 stock and a $1 rise in a $40 stock.
- $1 rise on a $400 share ($1 ÷ $400)
- +0.25% for that stock
- $1 rise on a $40 share ($1 ÷ $40)
- +2.5% for that stock
- Effect on a price-weighted index
- The same for both
A small percentage move in a high-priced blue chip can move the Dow as much as a big percentage move in a low-priced one.
Hypothetical prices for illustration.
#Are blue-chip stocks safe?
No stock is safe from losses. Investor.gov reminds investors that stock prices move down as well as up and that you can lose money [1]. It also notes that large-company stocks as a group have lost money on average about one out of every three years [1]. A $10,000 position in a blue chip that falls 30% is worth $7,000, however famous the name.
| The label suggests | The label does not mean |
|---|---|
| A large, established business | The share price cannot fall sharply |
| A history of growth | Growth will continue |
| Dividends are common | Dividends are fixed or required |
Holding a handful of blue chips is still concentrated. Spreading money across many companies is the idea behind diversification.

Frequently asked questions
Do blue-chip stocks always pay dividends?
No. Investor.gov says they generally do, but FINRA notes that a company may pay dividends without having to, and can cut or eliminate them [3].
Is there an official list of blue-chip stocks?
No. Indexes such as the Dow describe their members as blue chips, but no regulator keeps a blue-chip list.
