When analyzing IPO marketing presentations, you will frequently see claims like: "The issue is attractively priced at a Forward P/E of just 18x!" But what does this mean, and how does it compare to actual historical Trailing P/E?

1. Trailing P/E vs. Forward P/E Explained

  • Trailing P/E (Historical): Uses actual, audited earnings reported by the company over the preceding 12 months (Trailing Twelve Months or TTM). It is based on cold, verified accounting facts.
  • Forward P/E (Projected): Uses estimated future earnings for the upcoming financial year. It is based on forecasts and assumptions about continued growth.

2. How Bankers Annualize Recent Quarters

If an unlisted company has an exceptional single quarter (e.g., Q1 profit of ₹50 Crore due to seasonal Diwali sales), merchant bankers may multiply that single quarter by 4 to project an annualized profit of ₹200 Crore. This artificially depresses the Forward P/E, making an expensive IPO appear misleadingly cheap.

Assessing Investor Interest

Assess how institutional buyers weigh forward earnings projections by tracking category subscription on real-time IPO subscription data.

3. How to Spot Unrealistic Growth Projections

Compare the projected growth rate in the DRHP with the company's historical 3-year CAGR. If a company grew at 12% annually for three years, projecting an immediate 45% post-IPO jump requires rigorous justification.
