USE CASE

Which stocks are affected by this event?

Event impact analysis traces how a decision, a release or a shock reaches companies, from the names in the headline to the suppliers, customers, lenders and competitors connected to them. The useful answer is a short list of specific companies, each with the path and the evidence that links it to the event.

Beyond the obvious names

When tariffs change, oil spikes or a central bank surprises, the first list of affected stocks appears within minutes: the importers, the producers, the banks. Everyone has that list. The second-order names, the companies affected through who they buy from, sell to or borrow from, take longer to find and are often missed.

How to analyse the impact of an event

Work outward from the event, one connection at a time.

  • What exactly changed: which product, country, rate or rule?
  • Which companies does it touch first, and how large is their exposure?
  • Who is connected to those companies: suppliers, customers, lenders, competitors?
  • How did similar events play out before, for companies like these?
  • Which of your holdings or theses sit on one of those paths?

Common event types

The same method applies to the events investors ask about most.

  • Tariffs and trade rules: which companies import, export or compete with the affected goods.
  • Oil and commodity prices: who uses the input, who produces it, who passes the cost on.
  • Rate decisions: who borrows at floating rates, who refinances soon, who lends to them.
  • Conflicts and sanctions: which supply routes, customers and assets sit in the affected regions.
  • Regulatory changes: which business lines the rule reaches, directly and through customers.

An example

A new tariff is announced on an imported industrial metal. The first-order list is the domestic producers that may gain and the large importers that pay more. Tracing one step further shows a mid-sized equipment maker that buys most of its metal through a single importer, sells into a market where it cannot easily raise prices, and has no domestic supplier qualified yet.

That equipment maker never appears in tariff headlines, but it carries one of the clearest exposures. The analysis lists it with the supplier link and the customer evidence, so the analyst can check both.

Illustrative example. The companies are not real, and nothing on this page is investment advice.

How Clargus traces event impact

Clargus detects events in filings, news, regulators and macro releases, then traces their effects through suppliers, customers and lenders across its knowledge graph. A discovery run follows the chain the way an analyst would, choosing each next step from what the last one found, and reports the companies the event reaches with the path that led to each one. Theses that rest on an affected company are re-checked.

Clargus insights apply the same method to recurring news themes, one connection at a time.

Used by: Macro analysts, Traders, Hedge funds.

FAQs

Questions about this use case

How do I find which stocks are affected by an event?

Start with the companies the event touches directly, then follow their suppliers, customers, lenders and competitors, keeping the evidence for each link. The companies one or two steps away are where the less obvious effects sit.

What is a second-order effect of an event?

The impact on companies connected to the ones in the headline, rather than on those companies themselves, for example a supplier that loses orders when its customer is hit by a tariff.

Is an event impact analysis a trading recommendation?

No. It shows which companies an event reaches and why. Clargus is a research tool and does not give investment advice.
