Most income investors do not start with a blank sheet of paper.

They start with a list.

A model portfolio.
A newsletter recommendation.
A “best income funds” article.
A high-yield screen.
A portfolio from someone who seems to know what they are doing.

And honestly, that is understandable.

Income investing is messy. There are CEFs, ETFs, BDCs, REITs, preferred funds, covered-call funds, floating-rate funds, bond funds and dozens of other income vehicles. If you are trying to build a portfolio that produces cash flow, expert model portfolios can be a useful starting point.

The problem usually comes later.

Getting in is easy. Knowing when to review is harder.

A model portfolio can tell you what looked attractive at the time it was published.

But income assets change.

Distributions change.
NAV trends change.
Coverage changes.
Leverage matters.
Discounts move.
Management decisions matter.
Market regimes change.

And yet many investors keep holding the same names long after the original reason to own them has faded.

That is where income investing becomes dangerous.

Not because the investor made one bad decision.

But because nobody forced a second look.

A former favorite can quietly become a long-term problem

This is the part I care about most.

Many income assets do not collapse overnight. They deteriorate slowly.

The yield still looks attractive.
The monthly income still arrives.
The fund name still feels familiar.
The asset may still appear in old model portfolios or old articles.

But underneath the surface, the quality may have changed.

That is how a former favorite becomes a long-term problem.

And for income investors, that can be more damaging than missing the next hot idea.

I built IQ Score because I needed a better filter

I built IQ Score because I needed a better way to separate durable income assets from yield traps.

Not by guessing which stock will outperform.
Not by chasing the highest yield.
Not by blindly trusting someone else’s model portfolio.

The goal is simpler:

Do the income assets I own still deserve to be there?

IQ Score classifies income assets as:

• Friends — assets that currently pass the framework’s quality checks.
• Question Marks — assets where the picture is mixed and closer review is needed.
• Foes — assets where the income story looks weak, deteriorating or too risky to trust without a specific reason.

The point is not to create a magic buy list.

The point is to create a repeatable portfolio review process.

The real job is portfolio migration

For income investors, the real job is not always finding something new.

Often, the better question is:

What should I stop adding to?
What should I review more carefully?
Which holdings have quietly deteriorated?
Which assets still deserve fresh capital?
Where am I holding a Question Mark or Foe simply because I bought it years ago?

That is why I think about IQ Score as a portfolio migration tool.

Over time, the goal is to move an income portfolio away from Question Marks and Foes and toward Friends.

Slowly.
Deliberately.
With data.
Without pretending that every score is a trading signal.

Yield is not enough

A 12% yield is not a strategy.

Sometimes it is a warning label.

That does not mean high yield is always bad. It means yield needs context. Income investors need to know whether that income looks durable, whether the asset’s quality is improving or deteriorating, and whether the current classification still supports owning it.

That is what IQ Score is built to track.

The monthly discipline

IQ Score is designed around monthly snapshots.

Each snapshot freezes the published universe and shows:

• the current IQ Score;
• the classification;
• the trajectory;
• classification changes;
• reason summaries;
• and the historical IQ Timeline.

A single score tells you where an asset stands today.

The timeline shows how it got there.

That matters because income assets rarely become problems overnight. They often deteriorate quietly while the yield still looks attractive.

The question

So here is the question I want income investors to ask:

Do my income assets still deserve to be there?

Not:

What is the highest yield I can find?

Not:

Which ticker is popular this month?

Not:

What did an expert portfolio recommend two years ago?

But:

Does this asset still qualify?

That is the question IQ Score was built to answer.Expert model portfolios can help income investors get started. But they rarely tell you when a former favorite has quietly turned into a long-term problem.
