What drives the result

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.
