Understanding changes in working capital is crucial for analyzing a company's liquidity and operational efficiency. Many investors overlook how shifts in receivables, inventory, and payables can impact cash flow. For example, an increase in accounts receivable might look like growth, but it actually ties up cash. I found a really clear breakdown of this concept that helped me a lot to learm more about change in working capital. It explains the differences between positive and negative changes and how they reflect on the financial health of a business. Definitely worth a read if you're diving into cash flow analysis or preparing for an investment decision.
