Trailing Twelve Months (TTM)

What is TTM?

Trailing twelve months (TTM), sometimes referred to as last twelve months (LTM), is the 12-month interval of a company's financial performance that occurs before a designated point in time. 

How Does TTM Work?

TTM is a helpful statistic for reporting, comparing, and contrasting financial figures.

For example, an analyst issuing a report on October 15, 2019 will report trailing twelve months (TTM) earnings as those from October 1, 2018 to September 30, 2019. The analysts can, in turn, compare those earnings with other companies' TTM figures within a particular industry.

Why TTM Matters

Analysts and policymakers frequently use the trailing twelve months to gauge economic performance and to analyze data from the past year. It is important not to confuse trailing twelve months with the last fiscal year (LFY), which covers the organization's most recently-completed fiscal year.

TTM Yield

TTM yield is used to measure the performance of mutual fund or exchange-traded funds (ETF). It refers to the percentage of income a portfolio has generated for investors over the last 12 months. TTM yield is calculated by taking the weighted average of the yields inside a fund portfolio.
