Pareto's Principle, also known as the 80/20 rule, was discovered by Italian economist Vilfredo Pareto. It is a power law distribution that states that approximately 80% of the effects come from 20% of the causes. Pareto analyzed income statistics and concluded that income distribution is stable and does not change over time. However, he acknowledged that Pareto's Principle does not apply to the low-income group. Today, Pareto's Principle is considered valid only locally for income distribution. Pareto's Principle was supported by the Italian Fascist Party as a theory justifying the rule of the majority by an elite minority. Pareto's Principle suggests that about 20% of the key people in an organization bring most of the benefits, and when that 20% of key people are culled, 20% of the remaining 80% will again bring most of the benefits. This principle is often applied to various examples beyond economics, such as natural phenomena and social phenomena.

WACC (Weighted Average Cost of Capital) is an indicator that represents the average cost that a company needs to pay to raise capital. Specifically, it has the following characteristics: Cost of Capital:WACC represents the cost for a company to raise capital (equity and debt). Each type of capital (equity and debt) is proportionally weighted based on its market value. Benchmark for Investment Decisions:WACC represents the average cost that a company expects to pay to finance its business. Therefore, WACC is a common way to express the return that investors or companies demand to provide capital in one number. Discount Rate for Financial Modeling:WACC is used as a discount rate for future cash flows in financial modeling. Specifically, when evaluating the value of a business or company, WACC is used as a discount rate to discount free cash flow. The formula for calculating WACC is as follows: WACC = \left(\frac{E}{V} \times Re\right) + \left(\frac{D}{V} \times Rd \times (1 - T)\right) w

ROE (Return on Equity) is an important indicator for evaluating a company's profitability, and it is often referred to by investors when making stock investments. Specifically, ROE can be utilized in the following ways: Evaluating a company's profitability：ROE is an indicator that shows how efficiently a company is turning its equity into profit. Companies with high ROE are effectively using their equity to generate profits. Therefore, companies with high ROE may be attractive as investment targets.

Prospect theory is a decision-making model under uncertainty that describes how people make choices when the benefits or losses they will receive as a result of their choices and the probability of those benefits or losses are known. ¹ This theory is well known as a representative work in behavioral economics. Prospect theory is based on three main principles: 1. Loss aversion: People weigh losses more heavily than the same amount of gain. That is, losing $10,000 has a greater impact than gaining $10,000. 2. Diminishing sensitivity: As the absolute value of a gain or loss increases, the feeling of it becomes less noticeable. For example, if someone who already has $10,000 receives another $10,000, the pleasure they feel is less than the pleasure they felt when they first received $10,000. 3. Reference-point dependence: People evaluate gains and losses not in absolute terms, but as changes from a certain reference point (e.g., their current wealth). These principles help us understand h
