At the core of successful stock investing lies the ability to accurately estimate a stock's **intrinsic value**. The gap between market price and intrinsic value is the source of investment opportunities. But how do you calculate a stock's intrinsic value? In this article, we will walk through the most common **stock valuation methods** with practical examples for BIST investors.
Why Perform Stock Valuation?
Stock prices are determined by supply and demand dynamics. In the short term, emotions, news, and speculative activity can push prices away from intrinsic value. **Stock valuation** aims to uncover the true value beneath this noise and thereby set a **target price**.
If a stock's market price is below its calculated intrinsic value, it may represent a buying opportunity; if above, a sell or avoid decision may be warranted. In Warren Buffett's famous words, **price is what you pay, value is what you get**.
Discounted Cash Flow (DCF) Method
The discounted cash flow method is theoretically the most robust valuation approach. Its core logic is: **a company's value equals the sum of all its future cash flows, discounted to their present value.** Future cash flows are discounted to the present using a specific discount rate.
Key Steps in DCF
- Project free cash flow (FCF) for the next 5–10 years.
- Calculate terminal value to capture the period beyond the projection.
- Discount all cash flows to the present using the weighted average cost of capital (WACC).
- Subtract net debt from the total value to arrive at equity value.
- Divide equity value by the number of shares to find the per-share target price.
A key consideration when applying DCF to BIST is that the **discount rate** must reflect Turkey's risk premium and high-inflation environment. While WACC in developed markets is typically 8–10%, it can reach 20–30% in Turkey. This directly impacts target price calculations.
Multiples-Based (Comparable) Valuation
Multiples-based valuation is the most widely used method in practice. A target price is calculated using the multiples of comparable companies or the sector average. The most commonly used multiples are:
P/E (Price/Earnings) Multiple
A target price is calculated using the sector average or comparable companies' P/E ratio as a reference. For example, if the banking sector average P/E is 5 and GARAN's earnings per share is 20 TL, the P/E-based target price is 5 × 20 = 100 TL. This method is simple and fast but assumes earnings are sustainable.
P/B (Price/Book) Multiple
This method, particularly preferred in banking and asset-heavy sectors, multiplies the sector average P/B multiple by the company's book value to arrive at a target market value. For banks, the relationship between ROE and P/B is especially strong.
EV/EBITDA (Enterprise Value/EBITDA) Multiple
This multiple provides a capital-structure-neutral valuation and is ideal for comparing companies with different leverage levels. It is frequently used for industrial companies like EREGL and SISE. Enterprise value (EV) is calculated by adding net debt to market capitalization.
Dividend Discount Model (DDM)
The dividend discount model is used for companies that pay regular dividends. According to this model, **a stock's value equals the present value of all future dividends.** In its simplest form, the Gordon Growth Model is used:
**Stock Value = Expected Dividend / (Discount Rate – Dividend Growth Rate)**
This model can be applied to companies on BIST that pay regular dividends, such as THYAO and EREGL. However, due to Turkey's high inflation and variable dividend policies, growth rate and discount rate estimates must be made carefully. When calculating dividend yield, it is important to examine the company's 5-year dividend history and assess the sustainability of the payout ratio. DDM produces more reliable results for companies with stable dividend policies like BIMAS, while its use in cyclical sectors requires a more cautious approach.
Practical Approach: Use Multiple Methods
In the real world, no single valuation method is perfect. Professional analysts typically use **multiple methods** to determine a value range. This approach is known as **triangulation**.
- Calculate a base value using a DCF model.
- Perform comparable valuation using P/E and EV/EBITDA multiples.
- Support with DDM for dividend-paying companies.
- Compare results from different methods to establish a **target price range**.
- Apply a margin of safety to this range before making your final decision.
Key Considerations for Valuation on BIST
When performing valuations on the Turkish stock market, you need to account for several factors beyond the standard approaches used in developed markets. BIST, as an emerging market, has its own dynamics that can significantly impact valuation outcomes. Be sure to factor in the following:
- **Inflation effect:** Distinguish between nominal and real growth. Revenue growth can be deceptive in a high-inflation environment.
- **Currency risk:** Currency scenarios must be modeled for companies with foreign currency debt or revenue.
- **Holding discount:** The market value of holding companies like KCHOL and SAHOL typically trades below the sum of their subsidiaries' values. This discount can range from 15–40% on BIST.
- **Free float ratio:** Liquidity premium/discount in stocks with a low free float affects valuation.

Summary
Margin of Safety: The Insurance of Valuation
The **margin of safety** concept, introduced by Benjamin Graham, is the most important complement to the valuation process. Buying at a significant discount to your calculated intrinsic value creates a buffer zone to compensate for errors in your assumptions. For example, if you estimate a stock's intrinsic value at 100 TL, a 30% margin of safety means you would only consider buying at 70 TL or below. In volatile markets like BIST, keeping a wider margin of safety is prudent from a risk management perspective. You can use borsafolio.com's stock screener to identify stocks with potentially high margins of safety by examining multiple data.
Stock valuation is a critical skill that puts investment decisions on a rational foundation. DCF is the most comprehensive method but requires many assumptions. Multiples-based valuation is practical and fast but depends on selecting the right peer group. The dividend discount model is ideal for companies with stable dividends. The healthiest approach is to use multiple methods together to determine a value range. When investing on BIST, do not forget to incorporate Turkey-specific macroeconomic risks into your models.
