Motley Fool Hidden Gems Investing · Are Index Funds Making the Market “Irrational”? · 6 Jul 2026 podcast

Okay, so our second question from the mailbag today goes like this.

I'm a data analytics professional working in the co-op energy field.

I enjoy trying to apply analytical thinking to the market, but it's not my expertise.

I listen to the Fool podcast daily as I commute in my EV.

There is persistent talk US equities, specifically S&P 500 being overvalued.

I would really like to hear experts talk about expected retirement liquidations versus actual retirement liquidations by generation.

Thanks.

Here's what I like about this question, guys.

This person is admitting that they are not an expert, but that is okay.

You do not have to be an expert to be an investor.

And really, he's dialing into this analytical instinct here that he has as an individual investor, and he's saying, look, I feel like maybe there's a structural shift happening in the market, but some people are talking about it like it's an emotional shift,

So trying to understand the difference between structure and emotion, I really like the instincts here.

Rachel, what do you think?

So what I hear you saying here is that, yes, maybe perhaps ETFs and index funds have changed some structural market behavior compared to 30 years ago or 50 years ago.

Things are quantifiably different now.

My big question here is, if that's true, what do I have to do as a DIY investor?

Do I need to change things?

Do I need to be a rational investor?

as opposed to what I'm seeing is irrationality, or maybe we even need to define what does irrational even mean.

Rachel, I'm going to let you go first here with this big question.
