Testing Valuation: The valuation of trading securities requires comparing their carrying value with current market prices to ensure accuracy.

Market Quotations: Current market quotations provide the most reliable and up-to-date information on the fair value of securities.

Accounting Standards: This approach is consistent with accounting standards that require securities to be reported at fair value, reflecting any unrealized gains or losses.

Verification Process: Comparing the carrying value with market quotations helps verify that the securities are appropriately valued on the financial statements.
