What is a blue chip stock?
In one line: A blue chip stock is a share in a large, well-known, long-established company with a long record of running its business through good and bad years.
Where the name comes from
In poker, blue chips have traditionally been the highest-value chips. The name stuck to the stock market's biggest, most established companies about a hundred years ago.
There's no official list. Many people point to the 30 companies in the Dow Jones Industrial Average, or the largest names in the S&P 500 Index, as typical blue chips.
What they usually have in common
- Size. A large Market cap, often hundreds of billions of dollars.
- History. Decades in business and a well-known brand.
- Heavy trading. Millions of shares change hands daily, so the Spread is often a cent or two.
- Often a Dividend. Many pay part of their earnings to shareholders, though not all do.
A simple example with numbers
Two stocks, one news day:
- A blue chip at $200 moves 2% in a day. That's $4 a share, and for that kind of company it's a big day.
- A small, thinly traded stock at $3 moves 25%. That's 75 cents a share.
Big, busy stocks usually move in smaller percentage steps. That makes their charts smoother and fills more predictable. They still move, and an Earnings report can still send one up or down 10% overnight.
Why it matters
For beginners, blue chips are often easier to practice on. Plenty of news, tight costs and clean charts help you see turning points clearly. Our guide on how to read stock charts is a good next step.
A common mistake
Believing a blue chip can't fall far. Big names can drop hard and stay down for years. General Electric was one of the most famous blue chips in America, yet its shares fell sharply in 2017 and 2018, and it was removed from the Dow in 2018. Size from your stop on every stock, famous or not.
Questions
Are blue chip stocks safe?
No stock is safe from losses. Blue chips are usually less jumpy than small companies, but their prices can still fall a long way.
Is a blue chip stock the same as a large-cap stock?
They overlap a lot. "Large cap" is about size only. "Blue chip" also implies a long track record and a strong reputation.
