  2. Sum of perpetuities method - Wikipedia

    en.wikipedia.org/wiki/Sum_of_Perpetuities_Method

    SPM is derived from the compound interest formula via the present value of a perpetuity equation. The derivation requires the additional variables and , where is a company's retained earnings, and is a company's rate of return on equity. The following relationships are used in the derivation:

  3. Dividend discount model - Wikipedia

    en.wikipedia.org/wiki/Dividend_discount_model

    In financial economics, the dividend discount model (DDM) is a method of valuing the price of a company's capital stock or business value based on the assertion that intrinsic value is determined by the sum of future cash flows from dividend payments to shareholders, discounted back to their present value.

  4. Terminal value (finance) - Wikipedia

    en.wikipedia.org/wiki/Terminal_value_(finance)

    Also, the perpetuity growth rate assumes that free cash flow will continue to grow at a constant rate into perpetuity. Consider that a perpetuity growth rate exceeding the annualized growth of the S&P 500 and/or the U.S. GDP implies that the company's cash flow will outpace and eventually absorb these rather large values. Perhaps the greatest ...

  5. Hooke's law - Wikipedia

    en.wikipedia.org/wiki/Hooke's_law

    In physics, Hooke's law is an empirical law which states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring.

  6. Exponential growth - Wikipedia

    en.wikipedia.org/wiki/Exponential_growth

    Also, the effects of Moore's Law do not help the situation much because doubling processor speed merely increases the feasible problem size by a constant. E.g. if a slow processor can solve problems of size x in time t, then a processor twice as fast could only solve problems of size x + constant in the same time t. So exponentially complex ...

  7. Relative growth rate - Wikipedia

    en.wikipedia.org/wiki/Relative_growth_rate

    If the RGR is constant, i.e., =, a solution to this equation is = ⁡ Where: S(t) is the final size at time (t). S 0 is the initial size. k is the relative growth rate. A closely related concept is doubling time.

  8. What Is a Perpetuity? - AOL

    Perpetuity, in general, means “eternity.” And in finance, that concept of an everlasting state applies. A perpetuity describes a constant stream of cash with no end. But what is a perpetuity ...

  9. List of mathematical constants - Wikipedia

    en.wikipedia.org/wiki/List_of_mathematical_constants

    A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1] For example, the constant π may be defined as the ratio of the length of a circle's circumference to ...
