This situation is best classified as political risk, specifically regulatory risk, because the stock’s decline is driven by the anticipated impact of government action—pending regulations—on the company’s future profitability. Political risk includes changes in laws, rules, regulatory enforcement, tax policy, or other governmental decisions that can alter an issuer’s operating environment. When a company expects higher compliance costs, investors may reduce expected earnings or cash flow projections, which commonly leads to a lower valuation and therefore a lower stock price. That cause-and-effect relationship—government-driven change leading to a market value adjustment—is the core idea of political risk.

It is not credit risk, which focuses on whether a debt issuer can meet interest and principal payments. Stockholders are affected by equity value changes, and the prompt does not indicate an increased likelihood of default or missed payments on debt. It is not liquidity risk, which concerns the ability to sell the stock quickly at a fair price without significantly moving the market; the question does not mention thin trading, wide bid-ask spreads, or difficulty finding buyers. While capital (principal) risk broadly applies to most equity investments because market prices can decline, the question is asking for the specific type of risk causing the decline. Here, the driver is regulatory costs from pending government rules, which points directly to political risk.

This aligns with the SIE focus on identifying risk types and recognizing how external forces—especially governmental or regulatory developments—can affect securities markets and issuer valuations.
