📌 Chapter 8.11 — Commonly used ratios

Imagine you are reviewing the annual reports of two competing consumer electronics retailers listed on the NSE. Both companies show similar revenue growth, yet one is constantly plagued by liquidity crunches while the other maintains a robust cash position. When you calculate the Inventory Turnover Ratio—Cost of Goods Sold divided by Average Inventory—you realize the first company has a ratio of 4x, while the second enjoys a 10x turnover.

This metric immediately clarifies that the first company is struggling with product obsolescence or inefficient supply chain management, tying up precious working capital in unsold stock.

In practical terms, Inventory Turnover measures the number of times a company has sold and replaced its inventory during a given period. For an analyst, this is a proxy for operational efficiency and demand forecasting accuracy. A low turnover ratio often serves as a red flag, signaling that the company is overproducing or failing to move goods in a competitive market. In the Indian retail sector, where shelf space and seasonal trends dictate success, a declining turnover trend is frequently the precursor to margin-eroding discount sales and inventory write-offs.

When building your DCF models or valuation forecasts, this ratio directly influences your working capital assumptions. A company with high turnover requires less incremental working capital as it grows, which boosts Free Cash Flow to the Firm (FCFF). Conversely, a firm with poor inventory management will consistently consume cash to fund its bloated balance sheet, leading to a downward revision in your fair value estimate.

Analyzing this ratio alongside the Days Sales of Inventory (DSI) allows you to quantify exactly how many days of cash are trapped in the warehouse, providing a granular view of the company’s internal efficiency.

Ultimately, a high-quality research report goes beyond the headline revenue figures to explain the ‘velocity’ of the business. By monitoring changes in inventory turnover across quarters, you can identify early warning signs of a business model losing its competitive edge. Whether the inventory is building up due to a supply chain bottleneck or a genuine lack of consumer demand, the turnover ratio gives you the empirical evidence needed to challenge management’s commentary and refine your investment recommendation.1

Nuance

⚠️ Nuance
A common pitfall for candidates is the assumption that a ‘higher’ ratio is universally better. In reality, an extremely high inventory turnover ratio might indicate that a firm is operating with ‘just-in-time’ levels so lean that it risks stock-outs, potentially losing sales to competitors during demand spikes. An analyst must balance the goal of capital efficiency against the operational risk of failing to meet customer availability requirements.
