Why it matters

The 20 largest US-listed companies by market cap. Benchmark collections are a clean way to compare market leaders, index heavyweights and size segments without building a screen from scratch.

What to check next

Compare sector mix, valuation, quality and risk across the group rather than assuming larger companies are automatically safer.

Main risk

Large benchmark names can become crowded, expensive or overly exposed to one macro factor despite appearing diversified at first glance.

How are US Blue Chips stocks selected?

How often is the US Blue Chips list updated?

It is rebuilt from live market data, so the constituents and their rankings update as prices and company fundamentals change — there is no fixed, hand-edited list.

How should I use the Reward and Risk ratings?

Openbook's Reward rating combines a stock's growth, momentum, profitability and valuation into a single 0–100 score, and the Risk rating scores financial strength, volatility and size. Use them to compare names within this theme — broadly, a higher Reward alongside a lower Risk is more attractive. They are quantitative research signals, not investment advice.
