Market risk

As explained in Investing for Programmers

The risk that broad market movements cause an investment's value to decline, even when the individual investment performs well.

Market risk is the possibility that broad market trends reduce an investment’s value, even when its individual company performs well. Economic downturns, geopolitical events, and changing sentiment can produce widespread declines. section 7.1.2

Separate market-wide exposure from risks concentrated in particular investments:

  • Sector risk affects companies exposed to the same industry forces, such as regulation, demand shifts, or technological disruption. section 7.1.2
  • Asset-specific risk arises from company problems such as mismanagement, declining sales, product failures, or scandals. section 7.1.2
  • Risk matrices organize potential threats by likelihood and severity, helping prioritize mitigation for consequences that could be especially harmful. section 7.1.3

Stress-test a portfolio

For holdings such as Coca-Cola, Apple, and Pfizer, ask what another pandemic, a trade war, rising energy prices, or an anti-AI movement could do to prices and business prospects. Investigate unfamiliar catalysts before deciding whether the exposure is acceptable. section 7.1.3
