What is Relative Valuation? How to Compare BIST Stocks

Navigating through hundreds of companies listed on Borsa Istanbul (BIST) to pick the right investment can easily cause you to get lost amidst complex financial reports and instantaneous price fluctuations. One of the most fundamental and effective tools used by professional investors and fund managers to filter out this market noise is Relative Valuation.

While absolute valuation methods (such as Discounted Cash Flow - DCF) rely on countless assumptions and highly complex spreadsheet models, relative valuation takes the rationality of the market as its baseline to provide you with an instantly applicable, clear picture.

What is Relative Valuation? (The Real Estate Analogy)

The logic behind relative valuation is actually a decision-making mechanism we constantly use in our daily lives. Imagine you are going to buy a house. Calculating the construction cost, the amount of cement used, or the probable rental yield 20 years down the line (absolute valuation) is quite tedious.

Instead, you take a much more practical route: "How much are similar houses with the same square footage and number of rooms selling for in the same neighborhood?"

If a comparable house next door is selling for $500,000, while the house you are interested in is priced at $300,000, you immediately understand that the house is "relatively" cheap (trading at a discount). Stock comparison in financial markets is built on this exact same logic.

"Comparing Apples to Apples"

The first rule of conducting relative valuation in Borsa Istanbul is putting the right companies side by side. Different sectors have completely different profit margins, growth rates, and debt structures. Evaluating a software company and a heavy industry company using the same metrics will lead you to incorrect conclusions.

For a healthy comparison:

• Focus on Peers in the Same Sector: Comparing two different aviation companies, two energy giants, or two retail chains among themselves provides the most accurate data.
• Scale and Business Model: When comparing a sector leader (a major player) with a small, newly entered player, it must be remembered that the market will always pay a "trust premium" for the leader.

Core Comparison Metrics and the Power of "Market Cap"

In traditional fundamental analysis, ratios like P/E (Price-to-Earnings) or EV/EBITDA (Enterprise Value to EBITDA) are commonly used for relative valuation. However, these multiples can easily mislead investors as they are heavily affected by periodic (quarterly) profit or loss announcements.

The most transparent metric, free from these short-term fluctuations and reflecting the ultimate weight of the company in the stock market, is Market Capitalization (Market Cap).

Hypothetical Valuation Analysis with HisseCap

The most powerful insight relative valuation offers an investor is the answer to the question: "How big is the potential?" This is exactly where HisseCap provides a specialized algorithm that answers this question in seconds.

For instance, let's assume Company B, a mid-sized player in the aviation sector, will one day reach the current market size (Market Cap) of Company A, the sector leader. The HisseCap calculation engine takes the market cap of Company A, divides it by the outstanding shares of Company B, and gives you a precise Required Growth Multiplier.

Through this method, investors can:

1. See the mathematical boundaries of growth scenarios (understanding what is a dream and what is realistic).
2. Clearly calculate how many times the return a small company can offer if it reaches the volume of larger peers.
3. Build a smooth strategy purely based on "Company Value" without falling into the illusion of nominal stock prices.
