A Fund Rating That Will Not Tell You Why Is Just Someone Else’s Opinion

You look up a fund. You get a number, or four stars out of five, or a color. And then you sit there, because there is nothing to do with it.

Four stars does not tell you whether to buy. It does not tell you what is wrong with the one that got three. It is a conclusion handed to you with the reasoning removed, and the only thing you can do with a conclusion is take it or leave it.

A Number You Cannot Argue With Is Not Research

Compressing a fund into one figure is fine. Useful, even. Nobody wants to read a prospectus to decide between two S&P 500 trackers, and a rating that saves you that is doing real work.
But a fund’s outcome is driven by a handful of separate things that have almost nothing to do with each other. What it returned. What it returned relative to the risk it took. What it charges. Whether the person running it has been there eleven years or eleven months. How it sits against other funds doing the same job.

Any one of those can be the entire story, and they point in different directions. A fund can be perfectly competent at picking and still bleed out through its expense ratio. Another can post good headline returns by taking risk the investor never knowingly signed up for. Both can land on three stars. The three stars are identical. The situations are not remotely the same, and what you should do about them is not the same either.

Collapse all of it into one figure with no breakdown and you have not been given research. You have been given somebody’s verdict, with the argument stripped out.

What Five Parts Look Like in Practice

The fix is not a longer report. Nobody is going back to the prospectus. It is the same single number, with the components left visible underneath it.

hat is the approach IQ Dragon takes. It rates a fund from 1 to 100 on five weighted dimensions: historical performance and risk-adjusted returns at 25 percent each, expense efficiency at 20, manager tenure stability and peer-group ranking at 15 each. You still get one score, and you can still use it the lazy way. But each dimension shows what it contributed, so the weakest one is sitting right there in the open.

The difference that makes is practical. Say a fund comes in at 71, and the breakdown shows expense efficiency giving up more than half of its available points while everything else holds up fine. That is not a bad fund. That is a sound fund wearing a fee it does not need to be wearing, and the next move is obvious: go see what else tracks the same index for less.
Now take the same 71 where the shortfall sits in manager tenure instead. Completely different situation. Nothing is wrong with the fund today. You just have less history on the person steering it, and that is a thing to keep an eye on rather than a thing to fix this afternoon.
Same score. Two different problems, two opposite responses. You cannot get there from four stars, and you cannot get there from a number that will not break itself down.

Use the Score as a Starting Point

None of this means a composite rating is useless. It means it is the first step rather than the last one. The number tells you which funds are worth twenty more minutes. The components tell you what those twenty minutes should be spent on.

If a rating will not tell you which part is dragging, it has made itself impossible to check. And a figure you cannot check is not analysis. It is just an opinion wearing a number’s clothes.
