Assume that you work for a mutual fund and have the responsibility of selecting stocks to include in the fund's investment portfolio. You have been analyzing the financial statements of a chain of retail clothing stores and noticed that the company's cash flow from operations for the quarter ending on December 31 was negative even though the company had a small positive net operating income for the quarter. Further analysis indicated that most of the negative cash flow was due to a large increase in inventories. Should you be concerned?
