Large Caps
Established large companies (US$10–200bn).
Large-caps are the established, widely-followed companies at the core of most portfolios. This collection covers names between $10bn and $200bn, ranked by market capitalisation.
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.

Frequently asked questions
What is the Large Caps collection?
Established large companies (US$10–200bn). It currently holds 1716 stocks, each rated by Openbook's Reward and Risk scores. Large-caps are the established, widely-followed companies at the core of most portfolios.
How are Large Caps stocks selected?
Constituents are chosen by a rules-based screen over the full UK and US common-stock universe, then ranked by market capitalisation.
How often is the Large Caps 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.
Openbook Reward and Risk ratings and factor scores are quantitative signals for research, not investment advice. Data may be delayed. Some US-listed names carry partial factor coverage.
