What does Porter’s Five Forces framework collectively determine?

• A. Potential profitability and barrier strength in an industry.
• B. Only a firm’s internal resources.
• C. The company's stock price.
• D. The efficiency of the supply chain.

Answer: (C)

Porter’s Five Forces framework assesses how attractive an industry is by looking at the competitive forces that shape profitability. By evaluating the threat of new entrants, the bargaining power of suppliers and buyers, the threat of substitutes, and the rivalry among existing competitors, it estimates how easily firms can earn above-average returns. When these forces are strong, profitability tends to be lower and barriers to entry higher; when they’re weak, profits can be higher. This is not about a firm’s internal resources, stock price, or supply chain efficiency—those are separate considerations outside the industry-structure lens the framework uses.
