Price-to-earnings ratio (P/E): Calculated by dividing the current price of a stock by its EPS, the P/E ratio is a commonly quoted measure of stock value. In a nutshell, P/E tells you how much investors are paying for a dollar of a company's earnings.
Fraction theory: Just like the pivot point theory, it's also a popular intraday trading formula that relies on inputs collected from the previous trading day. The previous day's high (H), low (L), and closing (C) need to be added up and multiplied by 0.67 as: (H + L + C) x 0.67 = Y.
Determine company's earnings yield = EBIT / enterprise value. Determine company's return on capital = EBIT / (net fixed assets + working capital). Rank all companies above chosen market capitalization by highest earnings yield and highest return on capital (ranked as percentages).

Magic formula investing is a rule-based disciplined investing strategy to help investors understand value investing theory in a simple manner. He simplified the methodology of stock picking by listing stocks based on their price and return on capital.
Stock purchased/sold = Investment × 100/Market Price. Investment/Cash required = Stock × Market Price/100. Income/Dividend = Stock × Rate/100. Stock purchased/sold = Income × 100/Rate% Investment/Cash required = Income ×Market Price/Rate%
The Black-Scholes equation is a partial differential equation (PDE) that describes the price of a European option over time[1]. The equation was formulated by Fischer Black and Myron Scholes in 1973 and has since become known as Trillion Dollar Equation.
The mathematical calculation is a job task of a stockbroker. The mathematical calculation is helpful in predicting the securities movements in the financial market. A stockbroker is required to have the knowledge of statistics, algebra, probability, trigonometry, calculus one, calculus two and geometry.
