You can use the 4433 rule to select funds with good performance. Only funds with good short-term and long-term performance are stable, and Morningstar provides us with a query tool.

As shown in the figure, you can choose the first three years, and the performance of five years accounts for the first third of the average of the same kind!

The performance of the first three months and half a year accounts for a quarter of the average level of its kind!
