Marketable Securities: Trading


The term marketable securities, trading is used to describe investments in debt and equity securities that a company intends to buy and sell for profit. Marketable securities, including common stocks and bonds purchased for the purpose of trading, are typically held for a period of less than three months.

Marketable securities are a subset of short-term investments; as such, they appear on the company’s balance sheet as a current asset.


Marketable securities are temporary investments one company makes in another, with the hope of providing higher returns to its shareholders. There are two basic types of these securities:

  • Marketable Equity Securities: common or preferred stock investments held by a company in another large corporation.
  • Marketable Debt Securities: short term bonds held by one company in another large corporation.

The accounting treatment of marketable securities depends on whether or not the company acquiring these investments intends to hold them until they mature, trade them, or make them available for sale.

Marketable securities that are categorized as “trading” are those the company explicitly buys and sells for the purposes of generating short term profits. Generally, companies hold these securities for less than three months.

GAAP requires adjustments to the income statement as the fair market value of securities categorized as “trading” change over time. It’s important to note this change in value does not require a balance sheet adjustment. If the market price of a marketable security increases, the change in value is recorded as an unrealized holding gain on the income statement, while a decrease in the fair market price is classified as an unrealized holding loss.
