Answer

The income statement, the cash flow statement and the balance sheet are three of the financial statements that are frequently used by stock investors. A balance sheet is a financial statement that summarizes a company's assets, liabilities and shareholders' equity at a specific point in time.  An income statement is a financial statement that reports a company's financial performance over a specific accounting period.  A cash flow statement is a financial statement that shows how changes in balance sheet accounts and income affect cash and cash equivalents and breaks the analysis down to operating, investing and financing activities.
