This factor belongs to the growth factor, which measures the growth of the company's profitability. Generally speaking, the growth factor calculates the growth amount or growth rate based on historical financial data. This factor uses a single quarter year-on-year calculation method, which can more timely reflect the changes in the company's profitability in the short term. Among them, TTM (Trailing Twelve Months) data can smooth the impact of fluctuations in single-quarter financial data, making the analysis results more robust. Year-on-year changes are less affected by seasonal factors than month-on-month changes, so they are more conducive to horizontal comparison. Compared with the growth rate, the growth amount (that is, the absolute value difference) can better reflect the absolute scale of the company's profitability changes and is less sensitive to the basic value. This factor is particularly suitable for analyzing changes in a company's single-quarter performance, especially when there are significant fluctuations in performance, it can better reveal the company's development trends and potential risks.
