The maturity of each bond is different, but the average maturity of all bonds can be calculated. The technical name of this time is duration. The algorithm of duration is very professional, and it is not developed much.

Generally speaking, the duration of short-term debt funds is within 1 year; Medium-and long-term debt funds, the duration is generally more than 1 year.

The most accurate way to distinguish between long and short debt funds is to check their duration in the product manual. For example, a short-term debt fund clearly indicates that "the fund strives to keep the principal safe by controlling the duration of the investment portfolio for no more than one year".

However, many bond foundations directly mark "short debt" and "ultra-short debt" in their names; There are also some fund sales platforms that distinguish short-term debt funds in the classification, which is convenient for you to screen.
