Frequently asked questions

What is the Water & Utilities Infrastructure collection?

Water, regulated utilities and the grid. It currently holds 339 stocks, each rated by Openbook's Reward and Risk scores. The regulated, income-generating backbone of essential services — water, electricity, gas and waste — now central to electrification and climate resilience.

How are Water & Utilities Infrastructure 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 Water & Utilities Infrastructure 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.
