How does Porter’s Five Forces influence profitability?

• A. The intensity of each force shapes industry profitability; higher threat or power lowers potential profits.
• B. Rivalry has no effect on profitability.
• C. Only supplier power affects profits.
• D. Entry barriers always increase profits.

Answer: (A)

Porter’s Five Forces shows that profitability is set by competitive pressure from five sources: threat of new entrants, threat of substitutes, bargaining power of buyers, bargaining power of suppliers, and rivalry among existing firms. The overall profit potential of an industry depends on how intense these forces are. When the forces are strong, margins shrink and potential profits fall; when they’re weak, firms can earn higher profits. That’s why the best answer is that the intensity of each force shapes industry profitability, and higher threat or higher power lowers potential profits. Rivalry on its own matters a lot, but it’s not the only force influencing profits. Saying only supplier power affects profits ignores the other pressures. Entry barriers can influence profitability, but they don’t guarantee higher profits in all cases—other forces can still erode margins. Substitutes, buyer power, and new entrants all play a role in shaping profit potential.
