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 UK Blue Chips collection?
The 20 largest LSE-listed companies by market cap. It currently holds 20 stocks, each rated by Openbook's Reward and Risk scores. The heavyweights of the London market — the twenty largest LSE main-market companies by market capitalisation, refreshed from live data, spanning energy, pharma, banking, mining and consumer goods..
How are UK Blue Chips stocks selected?
The UK Blue Chips list ranks the largest London-listed companies by market capitalisation, refreshed from live market data. Foreign-domiciled cross-listings are assigned to their home market rather than double-counted.
How often is the UK 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.
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.
