Liquidity Ratios: The Safety Net

Imagine a person who owns a mansion worth $10 million but doesn't have $10 in their pocket to buy a loaf of bread. On paper, they are a multi-millionaire. In reality, they are starving. This is exactly what happens to companies that have great assets but poor Liquidity.

Liquidity refers to a company’s ability to pay its short-term debts (bills due within one year) using its short-term assets. While Profitability (Module 08) is the engine of the car, Liquidity is the fuel. Without fuel, even the best engine won't move.

1. The Big Three Liquidity Ratios

To measure the safety of a company, we use three primary ratios. They move from "Inclusive" to "Strict."

Ratio	The Formula	What it tells you
Current Ratio	Current Assets / Current Liabilities	The broadest measure. Can the company pay its 1-year bills by selling all short-term assets (including inventory)?
Quick Ratio (Acid Test)	(Current Assets - Inventory) / Current Liabilities	Strict measure. Inventory takes time to sell. This asks: "If sales stopped tomorrow, can we still pay our bills?"
Cash Ratio	Cash & Equivalents / Current Liabilities	The ultimate safety test. Measures only the actual cash and bank balance available right now.

The "Goldilocks" Principle

In liquidity, more is not always better.

• Too Low (< 1.0): The company is in a danger zone. It might have to sell its machinery or take emergency loans just to pay its electricity bill.
• Too High (> 3.0): The company is being "lazy." It has too much cash sitting in bank accounts earning low interest instead of reinvesting it in the business.

2. Solvency: The Long-Term Safety

While Liquidity is about the next 12 months, Solvency is about the next 10 years. A solvent company is one whose total assets exceed its total liabilities. The most important ratio here is the **Debt-to-Equity (D/E) Ratio**.

3. Interest Coverage Ratio: The Stress Test

A company might have a lot of debt, but can it afford the interest payments? This is where the Interest Coverage Ratio comes in. It is calculated as:

EBIT / Interest Expense

If the ratio is 5, it means the company makes $5 for every $1 it owes in interest. If the ratio is 1.1, the company is living on the edge. As a rule of thumb, always look for companies with an Interest Coverage > 3.0.

4. The Cash Conversion Cycle (CCC)

The CCC is a technical but powerful tool that measures the "Speed of Money." It tells you how many days it takes for a company to convert its investment in inventory back into cash.

5. Qualitative Liquidity: The "Smell Test"

Ratios can be manipulated (Window Dressing). To be a pro investor, ask these 1,000-word deep-dive questions:

• Unutilized Credit Lines: Does the company have a "standby" loan approved by a bank that they haven't used yet? This is a hidden safety net.
• Pledged Shares: Have the promoters put up their own shares as collateral for loans? If the stock price falls, the bank might sell those shares, causing a crash.
• Dividend Consistency: Is the company paying dividends while taking new loans? This is often a sign of poor capital management.

Summary of Module 9

• Liquidity is short-term survival; Solvency is long-term stability.
• A Current Ratio of 1.5 to 2.0 is the "Sweet Spot" for most industries.
• Always check Interest Coverage to see if the company can handle its debt burden.
• Watch out for high Debt-to-Equity ratios in cyclical industries (like Steel or Real Estate).

We have now assessed the quality of the business, its profitability, and its safety. The final question remains: Is the stock price fair? Even a great, safe, profitable company is a bad investment if you pay too much for it. In the final module, we master Valuation Ratios.
