A common rolling return period is trailing 12 months (TTM). Trailing 12 months is the term for the data from the past 12 consecutive months used for reporting financial figures. A company's trailing 12 months represents its financial performance for a 12-month period; it does not typically represent a fiscal-year ending period.
Using trailing 12-month (TTM) returns is an effective way to analyze the most recent financial data in an annualized format. Annualized data is important because it helps neutralize the effects of seasonality and dilutes the impact of non-recurring abnormalities in financial results, such as temporary changes in demand, expenses, or cash flow.
By using TTM, analysts can evaluate the most recent monthly or quarterly data rather than looking at older information that contains full fiscal or calendar year information. TTM charts are less useful for identifying short-term changes and more useful for forecasting.
