CORE DEFINITION

Under the perfect market assumptions (no taxes, no bankruptcy costs, etc.), the value of a company is independent of its capital structure (the proportion of debt to equity). The company's value depends only on its assets' ability to generate cash flow.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Thinking about the source of value. Although the real market is imperfect, it provides a benchmark: financial engineering (such as buybacks, issuing debt) can only change the distribution in the short term, not create value. True value growth can only come from improvement in the core business.

Anchor fast decisions

Under the perfect market assumptions (no taxes, no transaction costs, no bankruptcy costs, symmetric information), capital structure does not affect the total value of the firm: replacing equity with debt merely changes the distribution of residual claims, not the cash flow generation ability of the assets themselves. It provides a 'frictionless benchmark' to measure deviations caused by real-world frictions (tax shields, bankruptcy costs, agency costs).

Dollar Cost Averaging - DCA

Dollar Cost Averaging (DCA), also known as the "lazy man's investment method" or "periodic fixed-amount investment method," is an investment term that refers to a strategy of buying a fixed amount of a certain asset at specific intervals (e.g., once a month). The purpose of DCA is to mitigate the negative impact of asset volatility on the investor's final returns. DCA involves investing a fixed amount of money at regular, mechanical intervals into a specific asset (such as stocks, funds, foreign exchange, commodities, etc.) rather than investing all funds at once.
