A list of ADX companies is not a ready-made portfolio. It is a research universe containing businesses with different economics, accounting, ownership structures, capital needs, and trading liquidity. A useful sector framework helps investors ask the right questions without forcing every issuer into the same valuation template. The purpose is to create comparable evidence, not to rank companies from a single ratio.
Begin with the official issuer directory and disclosures, then build a one-page profile for each company. Record the ticker, legal name, sector, business segments, geographic exposure, reporting currency, fiscal year, major shareholders, free-float considerations, dividend policy, and recent corporate actions. This basic identity work prevents errors caused by similar names, reorganizations, subsidiaries, or stale third-party descriptions.
A common framework for every issuer
Before applying sector-specific measures, answer six universal questions. What problem does the company solve? How does it earn revenue and cash? What assets, licenses, contracts, brands, networks, or relationships protect its position? How much capital must be reinvested? Who controls the company and how are minority shareholders treated? What price already reflects the expected growth? These questions keep the analysis centered on value creation.
| Area | Evidence to collect | Warning signs |
|---|---|---|
| Business model | Revenue streams, customers, contracts, pricing, competitive advantages | Unclear segments, dependence on one customer, growth without economics |
| Profitability | Margins, returns on equity or capital, recurring versus one-off items | Adjusted metrics that never reconcile to cash |
| Cash flow | Operating cash flow, working capital, capital expenditure, free cash flow | Profit rises while cash conversion deteriorates |
| Balance sheet | Debt, maturities, interest rates, liquidity, guarantees, contingencies | Short-term funding for long-lived assets or weak coverage |
| Governance | Board structure, related parties, remuneration, audits, disclosures | Opaque transactions, repeated restatements, late filings |
| Valuation | Peer multiples, asset value, cash-flow scenarios, dividend capacity | A single optimistic target presented as certainty |
Banks and financial institutions
Banks require a balance-sheet-centered approach. Study loan growth, deposit mix, net interest margin, fee income, cost efficiency, asset quality, provisioning, capital adequacy, and liquidity. Rapid loan growth can support earnings but may increase future credit risk if underwriting weakens. A high return on equity can result from a strong franchise or from greater leverage, so decompose the source.
Examine concentration by sector, geography, large borrower, and related party where disclosed. Compare non-performing exposures and coverage over time, but check definitions and write-off practices. Funding stability matters: a bank reliant on concentrated or rate-sensitive deposits may face margin pressure. For Islamic banks, understand the structure and classification of financing and investment assets rather than simply mapping conventional-bank labels.
Energy, petrochemicals, and resource-linked businesses
Separate commodity exposure from contractual exposure. Some companies are directly sensitive to oil, gas, or product prices; others earn regulated, tariffed, fee-based, or long-term contracted revenue. Review production volumes, realized prices, operating costs, reserve or resource life where relevant, capital expenditure, maintenance needs, and contract counterparties. A high margin in a favorable commodity period may not be sustainable.
Model downside cases with lower prices, weaker volumes, project delays, or higher capital spending. Understand government concessions, offtake arrangements, joint ventures, and decommissioning obligations. For petrochemicals or processing businesses, feedstock terms and product spreads can matter more than the headline oil price. Currency and shipping exposure may also influence cash flow.
Utilities and infrastructure
Utilities can appear defensive because demand is essential, but the investment case depends on the regulatory and contract framework. Identify whether revenue is regulated, capacity-based, usage-based, inflation-linked, or merchant. Examine concession length, tariff reset mechanisms, counterparty credit, availability targets, fuel pass-through, and required capital expenditure. Long-lived assets can support predictable cash flows while also creating refinancing and maintenance risk.
Use debt-service coverage, interest coverage, maturity schedules, and project-level restrictions where available. A utility may distribute substantial cash while carrying high leverage because contracts support it, but the margin of safety depends on contract enforceability and asset performance. Growth projects should be evaluated separately from the operating portfolio.
Real estate and property developers
Property analysis must distinguish recurring income from development profit. Recurring rental, hospitality, or asset-management income can be valued differently from profits recognized when units are delivered. Track sales backlog, cash collection, construction progress, land bank, occupancy, rental rates, pipeline, and project-level financing. Revenue recognition can make results lumpy, so cash flow and customer advances deserve close attention.
Net asset value can be useful, but it depends on appraisal assumptions, capitalization rates, development costs, and the ability to monetize assets. Review the notes for valuation methods, related-party transactions, joint ventures, and guarantees. Interest rates affect both financing costs and buyer affordability. A low price-to-book ratio is not automatically cheap if assets are overvalued or cash generation is weak.
Telecommunications and digital infrastructure
For telecom operators, analyze subscriber trends, average revenue per user, churn, data usage, network investment, spectrum, enterprise services, and international operations. Mature connectivity businesses may produce substantial cash but require ongoing capital expenditure. New digital services can offer growth while carrying different margins and competitive risks. Separate reported revenue growth from acquisitions and currency effects.
Network quality, regulation, pricing discipline, and scale can support durable returns. However, high dividends should be tested against free cash flow after spectrum payments and investment. Where a company owns towers, data centers, or fintech assets, consider whether these businesses have different capital structures and valuation drivers from the core operator.
Industrials, logistics, and transport
Industrial businesses vary widely, so focus on capacity utilization, order backlog, customer concentration, input costs, energy costs, working capital, and maintenance capital expenditure. For logistics and transport, examine asset utilization, contract duration, fleet age, route economics, fuel exposure, and cyclicality. A growing backlog is useful only when margins, cancellation rights, and conversion timing are understood.
Pay attention to inventories, receivables, and contract assets. Fast reported growth can absorb cash if customers pay slowly or production must be funded in advance. Compare capital expenditure with depreciation and capacity plans. Acquisitions should be assessed for purchase price, integration, goodwill, and the financing burden rather than accepted as growth by default.
Consumer, retail, healthcare, and services
Consumer-facing businesses depend on brand, location, pricing, customer retention, and unit economics. Track like-for-like growth, gross margin, store or branch productivity, inventory turnover, digital sales, and expansion costs. For healthcare, consider payer mix, occupancy, clinician capacity, regulation, receivables, and the economics of new facilities. Revenue growth from opening sites is less valuable when mature-site returns are weak.
Services companies can be asset-light, but customer concentration and employee retention may create hidden risk. Examine contract renewals, recurring revenue, backlog, billing terms, and dependence on key personnel. Working-capital behavior often reveals whether growth is being financed by the company instead of by customers.
Technology and data-driven businesses
Technology labels can obscure very different models: software subscriptions, systems integration, artificial intelligence services, cybersecurity, digital platforms, hardware, or project work. Identify recurring versus project revenue, gross margin, research and development, customer acquisition cost, retention, backlog, and the level of capitalized development spending. Growth should be judged alongside cash burn and dilution.
Intangible assets, acquisitions, and related-party ecosystems can complicate valuation. Ask whether the company owns defensible intellectual property, has repeatable delivery, and can scale without matching growth in headcount or capital. Avoid valuing every technology company on revenue alone; unit economics and governance still matter.
Ownership, governance, and related parties
Strategic and government-linked shareholders can provide stability, access, and long-term capital, but investors should still review free float, board independence, related-party transactions, and capital-allocation decisions. Concentrated ownership may reduce trading liquidity and influence corporate actions. Read shareholder-meeting materials and governance reports rather than assuming alignment from reputation.
Look for consistent disclosure, transparent segment reporting, clear dividend decisions, and fair treatment in mergers, rights issues, or asset transfers. Related-party transactions are not automatically harmful, but terms, approvals, valuation, and economic rationale should be understandable. Governance analysis is about incentives and process, not labels.
Compare peers without forcing false precision
Choose peers with similar business models, geography, regulation, and capital intensity. A broad regional comparison can be useful, but accounting standards, ownership, currency, and market liquidity may differ. Use several lenses: profitability, growth, balance-sheet risk, cash conversion, dividend capacity, and valuation. Normalize one-off gains, acquisitions, and capital changes when possible.
Write a valuation range under base, downside, and upside assumptions. For banks, price-to-book and return on equity may be relevant; for mature cash generators, free cash flow and dividend capacity may matter; for property companies, asset values and recurring income can be central. The method should follow the economics. The listed-companies hub provides a compact issuer checklist, and the FTSE ADX indices guide explains how index membership differs from company quality.
Frequently asked questions
What is the best ratio for comparing ADX companies?
There is no universal best ratio. The appropriate measures depend on the sector, accounting, growth, leverage, and cash-flow pattern.
Is a government-linked company automatically safer?
No. Strategic ownership can be important, but investors still face business, valuation, liquidity, governance, and policy risks.
Should I avoid companies with low free float?
Low free float is not automatically negative, but it can affect liquidity, volatility, index weight, and the practicality of entering or exiting a position.
How many years of results should I review?
Use enough history to include different operating conditions. Several years plus the latest interim period is a reasonable starting point, with longer history for cyclical businesses.
