Earnings multiple per growth point.

What drives the result

Every ratio pairs an obligation with its resource, a profit with its base, or a price with its fundamental. Trends and peers matter more than single readings.

Recommendations

  • •Use forward growth, not trailing, for PEG.
  • •PEG fails for no-growth or loss firms.

Educational Content

Introduction

Ratios turn statements into decisions: liquidity says can we pay, solvency says can we survive, profitability says do we earn, and multiples say what the market charges for it.

Concept Explanation

Every ratio pairs an obligation with its resource, a profit with its base, or a price with its fundamental. Trends and peers matter more than single readings.

Applications

▸Lending and covenant checks
▸Equity screening on returns and multiples
▸Turnaround diagnostics on cash and turnover

Benefits

  • •Comparable across firms and time
  • •Pinpoints the binding constraint
  • •Links operations to valuation

Limitations

  • •Book vs market gaps
  • •Industry definitions differ
  • •One-offs distort trailing figures

Best Practices

  • •Use averages for balance-sheet bases
  • •Strip one-offs before judging
  • •Triangulate 2–3 ratios, never one

Common Misconceptions

Myth: Higher is always better
Truth: Excess cash or leverage-free balance sheets can drag returns.
Myth: One ratio decides
Truth: Liquidity without solvency (or profit without cash) misleads.

Practical Tips
