One fund advertises 214 percent.
The other, 19 percent a year.
10
Percent a year. That is 214 percent spread over the first fund's twelve years. The fund quoting 19 a year is earning nearly double.
A friend sent me two fund screenshots on Saturday, asking which one to buy. One was shouting a number in the hundreds. The other looked almost shy next to it, and he had half decided on the loud one. So I did the one bit of arithmetic both screenshots were counting on him to skip.
