Porter's Five Forces is a framework that helps analyze an industry's competitive landscape. It identifies five key forces: competitive rivalry, threat of new entrants, bargaining power of suppliers, bargaining power of buyers, and threat of substitute products. By understanding these forces, businesses can develop strategies to improve their competitive position and profitability.  

Porter's five forces is an analysis metric developed by Michael E. Porter in 1979. He developed five factors to analyse the competitive forces that shape the industry. Investors use the analysis made through Porter's five forces to understand the level and intensity of competition and the profit potential of a company within the industry.

Here are Porter's five forces in detail:

1. Rivalry in the industry:

This force analyses the level of competition within the industry, which may be positive or negative for a specific company. The following factors affect competitive rivalry:

• The existence of multiple competitors with similar sizes, products, and services.
• Slow industry growth intensifies competition as firms fight for market share.
• Homogenous products with low differentiation increase rivalry between companies as they compete majorly on the price of products and services.
• Companies are tempted to offer lower prices if the fixed prices are high or the products are perishable.

2. The threat of new entrants

This force analyses the possibility of new companies entering the industry. The easier it is for new firms to enter, the more competitive the industry becomes. The following factors prove to be the barriers to entry:

• Large and established firms have a large market share and cost advantage, making it harder for new businesses to enter.
• Existing companies have a large and loyal customer base, making it difficult for new businesses to find customers.
• In industries requiring high capital and investments, businesses may need help to enter.
• Extensive government policies, patents, and licensing requirements creating barriers for new entrants.

3. Bargaining power of suppliers

The next in Porter's five forces is the bargaining power of suppliers. This force examines how suppliers with bargaining power either reduce the quality of materials they provide or increase the prices of materials. Here are the factors that affect the bargaining power of suppliers:

• The existence of fewer suppliers in an industry increases their bargaining power.
• The service of providing an essential and unique product, increasing leverage and ultimate bargaining power.
• The related high cost of changing existing suppliers gives suppliers more bargaining power.
• The concentration of suppliers in a specific industry gives them more power over businesses and buyers.

4. Bargaining power of buyers

 The force analyses the power buyers have over businesses regarding the quality and pricing of their products or services. Here are the factors affecting the bargaining power of buyers:

• The existence of fewer buyers gives them more power over the quality and pricing of businesses' products and services.
• Low switching costs increase buyers’ power as they can easily change suppliers.
• The availability of homogeneous and low differentiative products and services makes it easier for buyers to switch and increases their bargaining power.
• The higher the knowledge of products and services with the buyers, the higher their bargaining power.

5. Threat of substitutes

The last of Porter's five forces is the threat of substitutes. This force examines the availability of alternative products or services that can fulfil the same needs as the products or services offered by the industry. Here are the factors that affect the threat of substitutes:

• The existence of a high number of substitutes or alternatives increases the threat of substitutes as switching is easy.
• If substitutes offer better or the same quality at a lower or same price, they pose a higher threat.
• Low switching costs to substitutes can increase the possibility of customers switching to alternative products or services.

If buyers think that the substitutes are equally valuable, the threat of substitutes increases.

Example of Porter's Five Forces

Let's apply Porter's Five Forces to the retail industry:

• Competitive rivalry: The retail sector is highly competitive, with numerous players vying for market share. This intense rivalry often leads to price wars, promotional offers, and fierce competition for customer loyalty.
• Supplier power: Large retailers have significant bargaining power over suppliers. They can negotiate favorable terms, such as lower prices and exclusive deals. Smaller retailers, however, may have less bargaining power and may be more susceptible to supplier price increases.
• Buyer power: Consumers in the retail industry have considerable power. They can easily switch between brands and retailers, especially with the rise of online shopping. Retailers must offer competitive prices, high-quality products, and exceptional customer service to retain customers.
• Threat of substitution: The increasing popularity of online shopping and e-commerce platforms poses a significant threat to traditional brick-and-mortar retailers. Consumers can now purchase a wide range of products online, often at lower prices and with greater convenience.
• Threat of new entrants: The relatively low barriers to entry in the retail industry, particularly in online retail, make it easier for new competitors to emerge. However, established retailers with strong brand recognition and economies of scale can deter potential entrants.

Here is the process of analysing stocks with Porter's five forces:

• Identify the industry: First, identify the industry in which the company operates. Porter's five forces are industry-specific.
• Evaluate company rivalry: Assess the number and strength of competitors to determine the level of competition within the industry.
• Analyse the threat of new entrants: Examine how easily new competitors can enter the industry. Look at barriers to entry, such as capital requirements, economies of scale, and regulatory obstacles.
• Assess the bargaining power of suppliers: Determine the level of influence suppliers have over the business. You can do this by determining the number of suppliers, cost of switching and uniqueness of their product.
• Evaluate the bargaining power of buyers: Analyse how much power buyers have in the industry. You can consider factors such as the number of buyers and the ease of switching to alternative products.
• Analyse the threat of substitutes: Analyse the availability of substitute products and services that buyers can replace with the existing products and services they use.

Advantages of Porter's Five Forces

Porter's Five Forces is a valuable tool for businesses seeking sustainable growth and competitive advantage. Here are some of its key benefits:

• Comprehensive analysis: Provides a holistic view of the competitive landscape, helping businesses identify key factors influencing their industry.
• Strategic insights: Enables businesses to assess their competitive position and make informed decisions about resource allocation and strategy development.
• Risk mitigation: Helps identify potential threats and challenges, allowing businesses to develop strategies to mitigate risks and protect their market position.
• Opportunity identification: Highlights potential opportunities for growth and innovation, such as untapped market segments or emerging trends.
• Long-term sustainability: Contributes to the development of sustainable business strategies by considering the dynamic nature of the competitive environment.

Disadvantages of Porter's Five Forces

While Porter's Five Forces is a powerful tool, it has some limitations:

• Oversimplification: The model can oversimplify complex market dynamics, potentially leading to a superficial analysis.
• Static nature: The framework may not adequately capture the dynamic nature of industries, which can change rapidly due to technological advancements or shifts in consumer preferences.
• Industry-level analysis: It primarily focuses on industry-level factors and may not fully account for company-specific strengths, weaknesses, and competitive advantages.
• Limited consideration of collaboration: The model may not fully capture the impact of collaborative relationships and partnerships between firms.

It's important to use Porter's Five Forces as a starting point for analysis and to complement it with other frameworks and tools to gain a more comprehensive understanding of the competitive landscape.

Porter's five forces examine various aspects of an industry and what makes a competitive environment for a specific business operating within it. You can use Porter's five forces to analyse companies and their stocks within an industry and combine the analysis with other technical and fundamental factors to make informed investment decisions.
