Learn stock analysis, from basics to advanced

ScripLens shows what has already happened: end-of-day prices and the figures companies have filed. This section explains what each number and chart means, how ScripLens calculates it, and what it cannot tell you. It is education, not investment advice.

  • Descriptive. Every figure is calculated from past data.
  • Neutral. Nothing here says what to buy, sell or hold.
  • Illustrative. Worked examples use made-up round numbers.

Levels

Level 1 · Basics
Shares, exchanges and indices

Level 2 · Reading the numbers
Company ratios and ownership

P/E, P/B, EPS, ROE, ROCE, debt-to-equity, margins, growth, dividend yield, promoter and institutional holding, and what each ratio leaves out.

Level 3 · Charts and returns

Medians and percentiles, volatility, beta, correlation, survivorship and look-ahead bias, sample size, and the Piotroski F-score and Altman Z'' models.

  • It does not forecast prices, returns or company results. Past performance does not indicate future results.
  • It does not rank companies or say that any figure is good or bad. A high or low value only describes where a number sits.
  • It does not consider your goals, time horizon, tax position or risk tolerance. For that, consult a SEBI-registered investment adviser.
