Fundamental (펀더멘털)

A term denoting the underlying strength and intrinsic value of an economy or company, and the core concept of fundamental analysis.

Fundamental (펀더멘털)

Overview

Fundamental (펀더멘털) is a term denoting the underlying strength or intrinsic value of an economy or a company. In macroeconomics it refers to the fundamental conditions of an economy such as growth rate, prices, employment, and the balance of payments; in microeconomics it refers to the factors that determine a company's intrinsic value, such as sales, profits, assets, and cash flow. The belief that even if asset prices move on short-term sentiment or supply and demand, they ultimately revert to fundamentals, has established itself as a core premise of traditional financial theory.

Etymology and Definition

'Fundamental' derives from the Latin fundamentum (foundation, basis), and in the English-speaking world it has been used since the 19th century to mean "that which serves as a basis." In the field of investing, it spread in earnest along with the value investing theory established by Benjamin Graham and David Dodd in the 1920s–30s. Graham's books Security Analysis and The Intelligent Investor set forth the principle that one should pay attention to a company's performance and asset value rather than its share price.

Macroeconomic Fundamentals

The fundamentals of a national economy are measured by indicators such as the following.

Growth: real GDP growth rate, potential growth rate, productivity growth rate
Prices: consumer price index (CPI), core inflation, expected inflation
Employment: unemployment rate, employment rate, hourly wage growth rate
External soundness: current account balance, foreign exchange reserves, external debt ratio
Fiscal: national debt ratio, fiscal balance, credit rating
Monetary and financial: policy interest rate, money supply, household debt ratio

In exchange rate theory, the expression "an exchange rate consistent with fundamentals" means the long-run equilibrium exchange rate such as purchasing power parity (PPP) or interest rate parity (IRP). The real effective exchange rate (REER) is a representative indicator that aggregates such macro fundamentals to assess the appropriateness of a currency's value.

Corporate Fundamentals and Fundamental Analysis

An individual company's fundamentals start from its financial statements. The three main pillars are sales and operating profit on the income statement, assets, liabilities, and equity on the balance sheet, and operating cash flow on the cash flow statement. To these are added qualitative elements such as industry structure, market share, competitive advantage (moat), management's capital allocation capability, and the regulatory environment.

The work of analyzing these to estimate intrinsic value and compare it with the market price is called fundamental analysis. Representative methodologies are as follows.

1. Top-down: analysis in the order of macroeconomy → industry → individual company

2. Bottom-up: constructing a portfolio starting from individual company analysis

3. Relative valuation: comparing multiples such as PER, PBR, EV/EBITDA, and PSR

4. Absolute valuation: DCF (discounted cash flow), DDM (dividend discount model), RIM (residual income model)

Fundamentals versus Technical Analysis

Whereas technical analysis is an approach that attempts to predict the future from patterns in past prices and trading volume, fundamental analysis focuses on the 'substance' of a company's performance and assets. The efficient market hypothesis (EMH) distinguishes the degree to which fundamental information is reflected in prices according to weak-form, semi-strong-form, and strong-form efficiency. If semi-strong-form efficiency holds, it leads to the conclusion that excess returns cannot be earned from publicly available financial information.

Limitations of Fundamentals

Even if fundamentals are good, prices may not respond immediately, and accounting fraud, information asymmetry, liquidity crises, and geopolitical shocks greatly widen the gap between fundamentals and prices. The 2008 global financial crisis and the 2020 COVID-19 shock showed that it is difficult to predict crises with fundamentals alone.

Latest Trends

In financial markets in 2024–2025, the discussion of fundamentals is evolving in three directions.

First, the spread of AI-based analysis. 'Quantamental' strategies, which extract fundamental signals by analyzing disclosures, earnings calls, and news in real time using natural language processing (NLP), have become close to standard among institutional investors. Attempts to estimate performance faster than traditional financial statements by combining alternative data (satellite imagery, card sales, app usage logs) have also increased.

Second, the reevaluation of macro fundamentals. As inflation and high interest rates have persisted since the pandemic, 'interest rate fundamentals' and 'fiscal soundness' have reemerged as key variables. Quantitative tightening (QT) by central banks around the world and geopolitical fragmentation are making it difficult even to estimate potential growth rates.

Third, the growing weight of ESG and intangible assets. As factors not captured in traditional financial statements—such as climate risk, human capital, and data assets—account for a substantial portion of corporate value, the very definition of fundamentals is broadening. The IASB and FASB are discussing expanded disclosure of intangible assets, and the EU has mandated disclosure of non-financial information through the CSRD.
