Balance Sheet

Balance sheets provide a snapshot of a company's financial health and its assets (such as cash, inventory, and property) and liabilities (like debts and obligations) at a specific point in time. For stock investors, balance sheets help assess the company's overall worth and evaluate its ability to meet financial obligations and support future growth.

Equity refers to the ownership interest or stake that shareholders have in a company, representing their claim on its assets and earnings after all debts and liabilities are paid.
